stomp test procedure - blink code pedal faults

[shogun]

All 1989–94 BMW vehicles equipped with a self diagnostic system have the ability to retrieve engine fault codes by counting MIL flashes. These are four-digit fault codes (pedal faults) and have different code numbers than those retrieved by the scan tool. Pedal fault codes can be retrieved with the ignition on, engine off, and with the gas pedal rapidly depressed to the floor five times without interruption.
See Table 4-6 for pedal code descriptions for 1989–94 models.

Important Tips for Reading Pedal Fault Codes
• Blink codes cannot be retrieved if the scan tool is communicating with the vehicle.
• Blink code retrieval can be used for comparison and backup to the scan tool.
• V12 engines have two ECMs, one for each engine bank. Codes need to be retrieved from each bank separately. The left engine bank is on the driver's side of the vehicle, which is
Bank 2. The right passenger side is Bank 1. Be aware that each bank's induction system (MAF sensor and intake runners) are physically located on the opposite bank. To access
the second ECM, depress the gas pedal to the floor six times. All cylinder 7–12 codes begin with a two.

Stomp test will NOT work either

[shogun]

Stomp test works only on U.S. specification cars, not on EURO, AU or Japan spec cars.
For USA that was mandatory.

BMW MOTRONIC 'PEDAL' FAULT CODES (Models 1989-94)
All 1989-94 BMW vehicles are equipped with a self diagnostic system for the detection of injection faults. When a fault is detected by the system the Electronic Control Unit (ECU) records the code corresponding to the defect in the ECU's memory until either:
1) The vehicle battery or the ECU is disconnected.
2) The engine is started 60 times with no recurrence of the fault.
3) The ECU memory is cleared using the Bosch KTS300, CARSOFT BMW software or the CS1000 BMW hand scanner.

look at the ETM, there are no limits for region, where car was made.
Fo example e36: If you have not the check engine lamp in your dashboard, just connect 1,2w lamp to 8pin of dme connector and "+". Enjoy.

[pol34]

In ETM there are no limits of region, where car was made. You have not a check engine lamp in dash board? Connect the 1.2w lamp to pin of DME and "+". Turn on engine, dont start, and make a test.
For 3er e36 8pin and "+".
My car -DME3.1 m50, e36 for Germany, works good. Infact, you just have not wire from DME to instrument cluster.

For 5er 34 and 7er e32- 15pin of DME and "+".

[hh3uunp]

Update this please. Messing around with my brothers 530i
Code 1000= massive vacuum leak

[johnqh]

I think code 1000 is "end of the codes". It simply didn't detect your leak.

[shogun]

we have tried it with wiring, on the EURO version of the E32 750 with the old 1.2 Motronic it does not work, with 1.7 it is possible to modify it I heard.
But as I have a Peake code reader and a GT1 scanner, I actually do not need the stomp test on my car.

Error Code List - Stomp Test OBD1


To read codes for an OBD I car, you start by turning the ignition key on (do not start the engine) and pressing the gas pedal to the floor five times within a period of five seconds. If you proceeded correctly, then the check engine lamp will light on for five seconds, then blink off, then blink on for 2.5 seconds, and then go off for another 2.5 seconds. After this, the computer will start to show you the trouble fault codes that are stored.

The codes are given by short flashes of the check engine light, followed by short pauses. The codes are all four digit numbers. For example, the trouble fault code for monitoring the battery voltage level is 1231. This would show up flashing as "flash - pause - flash - flash - pause - flash - flash - flash - pause - flash." I suggest having a pen and paper handy when you do this, as the codes have a tendency to flash faster than you would think.

If there is more than one fault code stored, then each code will be separated by a 2.5 second pause. When there are no more codes to be read, the computer will give the code 1000, which is one short flash, and then the light will remain off. Then the check engine light will flash a half-second and then turn off. To read the codes again, simply turn the ignition key off and on again and repeat the procedure with the gas pedal (five times within five seconds).

Here is a table that represents all of the possibly fault codes that can be read using this method:

Code Error Notes / Corrective Action
1000 End of output - no more fault codes This code shows the end of the stream of error codes, and tell you that the computer is finished showing them to you.
1444 No more faults This code shows that all faults have been fixed. Required to erase the computer's memory.
1211 DME Motronic Computer Fault This may indicate a problem with the DME computer. Most problems result in a dead computer that cannot give out codes, so this particular code is not seen too commonly. If the code does appear, start and rerun the test for about one minute. If the code reappears, then chances are that you need to replace your DME computer.
1215 Mass Air Flow Sensor Fault The mass air flow sensor measures the amount of air that is currently being drawn into the engine. A big hole in one of your fuel injection intake boots may cause the car to stall and generate this code.
1216 Throttle Position Switch Fault The later model Motronic systems used a potentiometer to measure throttle position and adjust fuel levels appropriately. If the 'pot' is not giving off the proper values, it will produce this code.
1218 DME Computer Output, Group #1 These two codes can be generated when there is a ground fault short circuit from B+ at one of the two DME Output Amplifier Stages. This code is not typically seen by itself, and is usually generated with a host of other codes. Possible problems may be O2 sensor heater relay, fuel evap system problem, EKP relay, ignition coil problem, a faulty idle speed actuator, etc. If you get this code, disconnect the DME and let it sit for 15 minutes, then recheck the codes. If it persists, and no other problems are found, then it is probably an internal DME problem. If the code goes away, then ignore it and call it an intermittent error.
1219 DME Computer Output, Group #2
1221 Oxygen Sensor (primary) The O2 sensor measures the mixture of the car. This code is generated if the sensor is unplugged or broken. Sensor values are read when the engine warmer than 70°C, and should be within 0.02 and 0.85 volts. Negative values indicate that the sensor needs to be replaced, and slow fluctuation indicate that the sensor is clogged with soot. Cars with catalytic converters that have been removed may push this code.
1212 Oxygen Sensor (secondary)
1222 Oxygen Sensor Lean/Rich Detect (primary) If the signal from the O2 sensor indicates a very lean or very rich mixture for more than 10 seconds, then the computer generates this code. It could mean a faulty O2 sensor, or a problem with another component.
1213 Oxygen Sensor Lean/Rich Detect (secondary)
1223 Coolant Temperature Sensor Measures the temperature of the coolant inside the engine block. Used to determine if the engine is warm or cold. Check the wiring and the expected resistance value of the sensor.
1224 Intake Air Temperature Sensor Measures the temperature of air entering into the engine's fuel injection system, and adjusts the mixture accordingly. Colder air is more dense than warmer air and needs to be compensated for.
1225 Knock Sensor #1 The knock sensor is used to detect pre-ignition that can damage the engine. If the knock sensor is triggered, it will back off the timing of the car, reducing the 'pinging.' A fault is generated if there is an open circuit, a ground fault, or if the sensor sends multiple signals that don't correspond to proper engine operation.
1226 Knock Sensor #2
1227 Knock Sensor #3
1228 Knock Sensor #4
1231 Battery Voltage / DME Relay Monitor Monitors the condition of the battery and charging system, and produces a fault if a component goes out of specification or fail.
1232 Throttle Idle Position Switch On older Motronic systems, this switch was used along with the wide open position switch as a primitive throttle position switch.
1233 Throttle Wide Open Switch See above.
1234 Speedometer "A" Signal This code is generated when the engine is under load, over 2500 RPM and no discernable speedometer signal can be detected for more than 10 seconds. Check the wiring harness, and also the instrument console.
1237 A/C Compressor cutoff The compressor is automatically turned off when accelerating from low speed under full throttle. This code indicates a fault in the cut-out circuit or its wiring.
1241 Mass Airflow Sensor Codes 1241 and 2241 can be incorrectly generated on 1992 and later models. The actual fault is a improperly operating idle air valve, and the need for an updated EPROM. See BMW bulletins for more details.
1242 A/C Compressor Signal This code is generated if there is a ground fault (short circuit) or if the system detects that the compressor unit is disconnected.
1243 Crankshaft Position Sensor This code is triggered when the crank angle sensor is disconnected, or generates a signal that is not accurate when compared to the other engine sensors.
1244 Camshaft Position Sensor Displayed when the signal from the camshaft pulse generator is out of spec or absent. May indicate a problem with the injector side of the DME output stage.
1245 AEGS Intervention - Electronic Transmission Many BMWs are equipped with electronic transmissions. If the transmission encounters a major problem, it will generate an emergency message, and your on-board computer should show "TRANSMISSION EMERGENCY PROGRAM." Ignition timing will retard when this program is run.
1247 Ignition Secondary Monitor
1251 Fuel Injector #1 (single or group) Check the injector or injector group for proper wire harness connectivity. Also check the injectors for a clear, wide stream pattern. Code 1283 (Fuel Injector Output Stage) may also be triggered in conjunction with this code.
1252 Fuel Injector #2 (single or group)
1253 Fuel Injector #3
1254 Fuel Injector #4
1255 Fuel Injector #5
1256 Fuel Injector #6
1257 Fuel Injector #7
1258 Fuel Injector #8
1261 Fuel Pump Relay Control This code is generated when there is a break or ground fault in the circuitry associated with the DME fuel pump relay. Check pin #3 of the DME or the output stage in the DME (DME version M1.3 only).
1262 Idle Speed Control This shows up if the idle speed actuator shows a ground fault, or if the car stalls from an idle above 600 RPM.
1263 Fuel Tank Evaporative System (EVAP) The fuel tank evaporative system has a purge control valve that generates this code if there is a short circuit or open connection (DME version M1.3 only).
1264 Oxygen Sensor Heating Element This code is triggered if there is an open circuit or a short within the oxygen heating element circuit. Check the O2 heating element relay and also the air pump relay.
1265 Check Engine Lamp If the lamp in the dashboard burns out or shorts to ground, then this code is generated.
1266 VANOS System Check the wiring or the relay associated with the VANOS system (variable camshaft adjustment).
1267 Air Pump Relay Control Check the air pump relay and wiring (were applicable).
1271 Ignition Coil #1 An open-circuit or ground fault in the ignition wiring has occurred with an ignition coil. Place a timing light on the ignition wires and check for a signal. Also check the wires for faults, and check the spark plugs too.
1271 Ignition Coil #2
1271 Ignition Coil #3
1271 Ignition Coil #4
1271 Ignition Coil #5
1271 Ignition Coil #6
1271 Ignition Coil #7
1271 Ignition Coil #8
1281 DME Memory Unit Supply This indicates a fault with the internal memory of the DME computer. This is sometimes caused by low battery voltage. Delete the codes, and disconnect the DME for 15 minutes. Then reconnect, let the car idle for five minutes, and then drive over 30 mph for more than five minutes. Recheck the codes - if it occurs again, the DME is faulty and should be replaced.
1282 Fault Code Memory This code occurs when the DME generates a set of conflicting codes. Disconnect the DME for 15 minutes, reconnect, and then simulate a fault code, like unplugging the air flow sensor or idle actuator. If the code reoccurs, then you will need to replace the DME.
1283 Fuel Injector Output Stage This code is generated when there is a short circuit or open connection between the wiring from the DME to an injector or injector stage.
1284 Knock Control Test Pulse The ECU periodically checks the knock sensor circuitry by sending a test pulse through the system. This code indicates that a test was performed, but no pulse was registered. Check the wiring and knock sensors.

Stomp test works only on U.S. specification cars, not on EURO, AU or Japan spec cars.
For USA that was mandatory.

Not quite correct.
At least EC cars just don't have the bulb in the cluster. Fitting a bulb enables the CEL and stomp test works just fine.

[shogun]

Not quite correct, Wolf, we are talking here about E34 and E32 models. Since more than 10 !! years we are discussing that on German forums. Some do NOT work at all, no matter if you install a bulb or not, some modern ones work with a bulb and wire modifications and a switch.

Read this from 2009, we discussed that many times on the 7-forum and Stiefelknecht tells you here that the wires are not connected on the EURO model even on his E32 740i 12/92, not only the bulb, and you need a switch because the bulb does not go off. And that has a modern M60 Motronic already.
http://www.7-forum.com/forum/5/frage-stomp-test-118240.html


nein die graue Leitung von der DME zu X16:23 war nicht verlegt, sie geht zwar von der DME weg, muss aber irgendwo im Kabelbaum zurückgebunden sein.Ich hab sie dann kurzerhand nach X16 verlegt, von X16 zu X502:3 war es bei mir verlegt.
Das Birnchen erklärt sich von selbst wenn du das Cockpit mit der Rückseite vor dir liegen hast, glaube das 2te rechts unten, steht aber in den Kunststoff eingepresst.Wichtig ist eben dass du einen erreichbaren Schalter dazwischen baust, da die Lampe bei DE-Ausführung nicht erlischt

2005: http://www.7-forum.com/forum/5/check-engine-lampe-37023.html

There is more on the 7-forum on this, we are talking here about E32/E34 clusters and there were 3 different versions for the EURO already. Grey, white, blue backplate. And also the Motronics on EURO E32, even the old M1.1 was used in the oldest E32 1986/7.
Fugo in 2006:
OBD diagnose fur 750 ab 5/91 mit DME 1.7, fur europe die lampe CHECK ENGINE funktionieret nicht, do must verwenden neue kabel ECU I pin8 + ECU II pin 8 (motronic I und II identisch pin) und neue kabel Instrumental panel konektor X502 pin3 (und gutt birne CHECK ENGINE), ich habe in meine 750, fur zweite banke fehler code must depress gas pedal 6x mal. To Erich: Ja verstehen gut. Funktioniert nicht mit DME 1.2 (bis 05/91)!!!

So Fugo has tested it and confirms it does not work on a 750 EURO with DME 1.2 up to built year 05/1991. And I can confirm this, as I have also tested it on my 11/1988 E32 750 with M1.2 Japan/EURO spec, it does NOT work.

Another one in 2009 on a BMW E32 750i EZ 3/91:
Habe mal das Kabel mit Ohmmeter kontrolliert und eine Verbindung mit der Motronic gesucht, aber nichts gefunden. Habe aber schon mal ein Lämpchen in die Kombi eingesteckt. ich wollte mir das Kabel sparen, um es durch das Armaturenbrett zu ziehen.Mario

And the M30 M1.1 is stone age in electronics, that can store a max. of 5 faults! Then M1.3, M1.2, M1.7 and the M60 Motronic for E32. And the other E34 Motronics.
http://www.7-forum.com/forum/5/nochmals-unrunder-motorlauf-m70-50661.html


Self Diagnostic function
The Motronic 1.3 system has a self-test capability that regularly examines the signals from engine sensors and internally logs a code in the event of a fault being present. This code can be extracted from the Motronic Serial Port by a suitable Fault Code Reader. If the fault clears, the code will remain logged until wiped clean with a suitable FCR, or until the engine has been started for more than 5 times - when the fault code is self initialising. An ECU that retains codes for faults of an intermittent nature is a valuable aid to fault diagnosis. Motronic 1.1 1987 to 1988: The ECU will store a maximum of 5 fault codes.

[wokke]

Uups, I meant to be in the E31 forum. Sorry about that.
On those ECE cars it is indeed just the bulb, nothing else.

[cirrusblau]

shogun, my car is japanese-spec 10/88 production. the stomp test works on mine.

[shogun]

That sounds strange, we did not have the regulations here that the cars had to be equipped for that. Can you post your VIN? Did you modify something?
Never heard here in Japan from someone with an E34, and especially that old built year, that the stomp test works. Your model year 1988 would be from 08/09 1987! with Motronic HARDWARE 1.3 12141738168.
And because it also does not work on my 11/88 E32, I have a Peake tester for the simple things, but for these old built years also the Peake is not able to show many faults, in the Peake manual a 1988 E34 535 is even not listed. But they show it for 1989, E34 535, list K1, and all codes which could be found are:
1 DME unit selftest
3 electrical fuel pump relay
4 idle speed actuator open
5 evaporative purge control valve
7 airflow meter
0A emission lambda control
0F check engine lamp
10 fuel injectors 1,3,5
11 fuel injectors 2,4,6
16 idle speed actuator closed
17 oxy sensor heating relay
1C oxy sensor
1d vehicle speed signal not present
21 AT-kick-down prebent solenoid valve
25 control unit supply
26 ASC//DWA
28 A/C compressor
2b idle CO poti
2c intake ait temp sensor
2d coolant temp sensor
32 engine drag torque control /MSR
33 ignition timing intervention
34 idle switch
35 full load switch
36 torque converter clutch
64 unspecified DME output stage

*code definitions in that manual refers to US specifications only, and does NOT include any non-US variant, stated by Peake.

[cirrusblau]

here's my vin: 2895739

i know it works because i had a CEL before and tried the test. threw me a 1221. turns out i didn't re-attach the oxygen sensor properly. i didn't do any modification.

If you proceeded correctly, then the check engine lamp will light on for five seconds, then blink off, then blink on for 2.5 seconds, and then go off for another 2.5 seconds. After this, the computer will start to show you the trouble fault codes that are stored.


Turning the ignition key on : the check engine lamp is on and stays on!

If I put the key on the first position then the only display is the odometer, is this the one I use "first click" but no check engine light on after 3 or 4 secs, this is a model 1994 E32, I ran the vin decode, it was built on Nov 1993,

Trying to find out about an high idle issue - but it might be as simple as a stuck mat.

[shogun]

Turn the ignition switch to the 'engine run' position.
Depress the gas pedal to the floor 5 times.

[Ricky318i]

Hi, is there a list of the diagnostic codes that can be read from the OBC on my E34 1991 535i?

The codes are:

C1
52
C3
04
C5
C6
E7
70
07

[shogun]

Do you mean unlocking the OBC? http://bmwe32.masscom.net/johan/obc_secrets/obc_secrets.html

[Ricky318i]

Yes, I followed that procedure to unlock that tests in the OBC. I then did test 19 and came up with those error codes. Any idea where i can find a list of explanations?

[shogun]

That are for sure no error codes. Test # 19 is: Lock/Unlock OBC test functions (Sum of month and date to unlock or lock) http://www.unofficialbmw.com/all/electrical/all_obc_secret_codes.html

This most probably also is possible with older E32: Older E34 bulb wiring
In '88 and '89 E34 (maybe early '90) the PROM in the Motronic computer was not ready to accept the check engine light for the instrument cluster and when a bulb was installed in the socket in the cluster it would flash all the time when driving along even though no fault codes are registered. But if the 5 stomp test on the pedal was done it did activate the code retrieval system and the light would flash in correct sequence. Now there are 2 ways of getting around this constant flashing of the light when driving: putting a newer eprom or following the procedure.

1. Remove instrument cluster from dash board and locate the socket where the check engine light is meant to be installed.
2. Now get the instrument cluster bulb holder (without a bulb in it) and the 3 feet of wire and cut 2 feet off it. Dont throw the left over foot of wire away we need that later on.
3. Bare the ends of the wire and feed them through the small spaces in the end of the holder that produdes from the cluster when the holder is installed. Now solder the ends of the wire onto the contacts in the holder that the bulb usually seats onto. I have found that removing the contacts from the holder is best as the heat from the iron would probably melt the holder.When soldered, insert the contacts again into position in the bulb holder. Now bare the opposite ends of the wire and crimp 2 connectors. Now you should have something that looks like that.
4. Now install the bulb holder in the socket in the instrument panel where the check engine light is meant to be and feed the remaining wire through the dash. Make it so the crimped connector ends exit the lower dash somewhere out of a gap under the dash in the foot well where the steering column slides when adjusted for reach. Install the instrument panel back into dash.
5. With the remaining wire crimp the remaining connectors to one end and on the opposite end solder the light bulb contacts to the wire then wrap in duct tape to insulate from shorting out this should looks something like that.
6. Now to check to see if it works push the crimped connectors together from the dash wires to the bulb wires and do the 5 pedal stomp as descibed above and the bulb should light with the appropriate flash sequence.
7. If everything checks out ok then remove the bulb wire and store away in the tool box in the boot lid and the wire in the dash, just push up into the trim panel somewhere to hide when not in use.

I JUST used this old post to get all of the codes today when testing my e32. Very helpful.

I recorded this DIY to demonstrate the stomp test, which I totally forgot existed until I bought this e32:

look at the ETM, there are no limits for region, where car was made.
Fo example e36: If you have not the check engine lamp in your dashboard, just connect 1,2w lamp to 8pin of dme connector and "+". Enjoy.

Just so I get this right.. you connect a 1.2w bulb between the 15th pin and the + and the you go to the drivers seat and do the stomp test, then your bulb will flash like the CEL would?

I know this is an old post, but I hope someone sees this.

[shogun]

I would be very, very careful with such wire bridges, in worst case you can destroy your expensive DME with such bridging of pins when you by mistake touch the wrong one.
Safest and easiest is you get a used Peake fault code reader, that is very handy, you stick it into the 20-pin diagnostic port, select the code reading function, then it checks and you get codes which you then find explained in the Peake user manual.

Shogun.. I don't know what this forum would be without you. I have taken your advice, and booked a time at a shop that have the required diagnostics tools.

By the way, I still haven't recieved the sun blind handles I ordered from you. Will let you know when they come in!

Thanks again.

good idea to visit a shop, the stomp test is anyway very limited, the pro tools of the shops can go much deeper into the systems and can get more detailed info. Sun blind handles were shipped from Japan to Denmark 26.10., nowadays it takes a very long time with shipping and to many countries the post office even does not accept any mail. Much less flights, just be patient.

how to check for code 1234 Vehicle Speed Sensor (Speedometer A Signal) ?

[shogun]

1234 Vehicle Speed Sensor (Speedometer A Signal): This code is stored when no plausible speed signal is detected while driving. The requirements are an engine speed >2500 rpm and under load for more than 10 seconds. Check the speedometer function and the wire to the DME. Is the speedometer working normal? If not, the sensor on the diff http://www.bmwe34.net/E34main/Maintenance/Electrical/speed_sensor.htm clean it, check for oxidation, check the wires on the rear of the diff.
If your speedometer still operates normally, nothing is wrong with it.

Just adding to the stomp test topic on the previous page. ECE 11/88 730i with the original Motronic 1.3 (matching vin) works perfectly fine with the original grey and blue gen 3 cluster.

there a list of the diagnostic codes that can be read from the OBC test number 15 or 16 I don’t remember what test number on my E32 1990 has more deep diagnostic information about EEPROM

The codes are:

C1
52
C3
04
C5
C6
E7
70
and one of the functions written EEPROM
07
719320

What does 16 PORT values inputs & output mean ? And test 17 on display what does 00.64PROM mean ?

[Annddrriy]

Functions 15 16 and 17
Especially the functions 15 16 and 17 are a bit cloudy at the moment. If enough people are interested. He can try to setup a small database with values related to things like: production date OBC type E32 Engine type transmission type Left/Right hand drive Stretched version seat heaters front/back available alarm Compartment heaters time switched by the OBC luxury package BMW software upgrade ?

[Annddrriy]

That cloudy feature it’s interesting not only for me here on this forum thousands of fans would like to know what it is ? Give us a gift and thousands will be grateful to you !

The test 20 is important to dial correct numbers for fuel efficiency. One time I did dial by mistake 0001 and the engine was stop running and transmission failed. On dashboard was transmission program. Then I reset the battery and all returned to function normally.

no, test 20 will not stop the engine or adjust the fuel consumption, it is only for: Fuel consumption correction = that means the info on the OBC about fuel consumption can be corrected but not the real engine fuel consumption.
also in the document from Timm is mentioned: 0 1000 CORR Setting Correction Factor for OBC Fuel Consumption *2 1000/100/10/1 to change, S/R to save. NOTE: On my 730i V8 this is set to 1000 which is the default setting
15, 16 and 17 are also explained here https://www.meeknet.co.uk/E32/E32_OBC_Unlock.htm

The vehicles not safe to drive if computer is unlocked ? When testing sequence is completed the computer has to be relocked then you good to go.

[Annddrriy]

What does test 15 fault memory for M.F.G purposes mean ?

[shogun]

that is for Manufacturing = M.F.G Purposes of the OBC, see for example page 11, 14 http://www.e38.org/e32/BMW_pdfs/OBC_info.pdf
That are internal BMW/Manufacturer Info, but no effect for you as driver.
14 Software date
15 DIAG values (Fault memory)
16 PORT values (inputs & outputs)
17 PROM values (all data for OBC)
18 "Code" alarm horn beeping or continuous tone

"The vehicles not safe to drive if computer is unlocked ? ">>>> safe, my one is always unlocked

Ok thanks !
