[328 Power 04]

I have a buddy with an 05' e53 and he's having some electrical issues. It's the battery or the alternator. Were putting in a new battery tonight. I was wondering if I can test the alternator with my software? Besides reading the output voltage is there anyway to moniter output amps or anything that would help me determine if it's bad or not?

E53s are quite simple, so I don't think there is a module reporting on the charging system.. But I would certainly look through all the "service functions" in ISTA before giving up. Newer BMWs have a test plan that automatically check for battery drain across the system. But these are the really new ones.

A simple voltage test with engine running, and compared to engine off should be enough.

Ya we've been watching the voltage over the past few days, but it's acting a lil wierd. He drained the battery, then slow charged it. All was well yesterday, but today the battery light came on.....

thanks!

OK this is probably the stupidest question in this thread.

How do I reset Maintenance and Inspection lights with this? I have been digging for 15 minutes and can't find it.
(For the record, looking to do this on my m44 318ti, not the M Roadster. Someone has borrowed my PEAKE tool)

key in ignition on run, engine off,

pin 7 to ground (pin 19, or just body of car) for 4 seconds for oil interval, 9-10 seconds for Inspection reset.

Does anyone have any info of other usable cables? This one maybe $18.50, but it's an extra $30+ for shipping to me..... There are others which seem to be the same, but I'm not sure

Ignore this post

I was able to code window operation at anytime which is was helpfull yesterday, as I was working on the sliders. Windows roll up and down now with or with out the key, doors opened or closed.

[Paul1940]

WOW what a find!!!! I have been scratching around all of the Bimmer forums for about 6 months and this is the first thread I have found dedicated to the use of INPA with the Z3. The Bimmerfest thread for the older Z3's is a good one too (I haven't read it all yet) but this one is a godsend.

Help is needed. Florida will not allow me to title the car until all the cluster alerts are cleared.

This Z3 I bought is a crashed vehicle. It had an airbag light, a DSC light and a 'yellow' BRAKE alert. I read the codes with my C110 code reader producing 10 codes under the airbag SRS module:
02 (002) SEATBELT TENSIONER DRIVER
03 (003) Seatbelt tensioner, front passenger
11 (017) Power supply
15 (021) Seat belt buckle, front passenger
16 (022) Sensor for side airbag, left
16 (022) Sensor for side airbag, left
1A (026) Seat occupancy recognition 1
1A (026) Seat occupancy recognition 1
1B (027) Crash telegram memory
F0 (240) Control unit fault, internal
I replaced a pair of blown belt tensioners (listed in the fault codes), cleared the codes and re-read the codes. They all came back! No matter what I did, all the codes came back every time. Saw ad for MyAirBags.com, called, found out that some codes cannot be cleared but module can be "reset". So sent SRS module off to GA with $40 for module "resetting". When I got it back, installed it and re-read codes again. EUREKA only two codes came back!
16 (022) Sensor for side airbag, left
1A (026) Seat occupancy recognition 1
I replaced the left side airbag crash module and put in a passenger seat sensor simulator AND HURRAH the airbag light is OUT!! Half done!!

Here is my question #1. What did MyAirBags do that I could not do with my C110 BMW code reader? Question #2. Would I have been able to accomplish what they did if I had had INPA up and running?

Under ABS DSC module:
5DF4 System voltage < 9 volts
5DF5 Internal fault control unit
5E1A CAN data error from DME/DDE (DSC lamp on until ignition reset)
5E26 Control unit, voltage supply, sensors
5E5D Level sensor, brake fluid
I cleared the codes multiple times but they all always came back. I suspect the battery may have dropped in voltage at some point when vehicle was stored. Question #3. Would that cause these faults? I read somewhere that the DSC momentary switch would light up the DSC and yellow BRAKE alerts when DSC is disabled. But they won't go out with another push of the switch. Question #4. What does the note about ignition reset mean? Question #5. Will INPA provide any way to clear these codes to see if they really will come back, indicating a real fault? Solving this issue will allow titling of the vehicle.

My last set of questions revolves around my stupidity. I purchased AK90+ to make additional keys for my two Z3's. As a person involved with electronic maintenance for decades, I should know better than to introduce new variables to an already puzzling situation. But thinking I knew what I was doing, I went ahead and tried making another key. Well, I did something WRONG?? and now no starter (no voltage out of EWS to starter). My original key causes door open chime and will turn the ignition switch lighting up cluster but no starter. Read codes:
Under DME: DTC
80 EWS transmission/parity
Under EWS:
42 Key #5, incorrect random code (Key #5 is in ignition switch)
81 Key #9, incorrect password (No key #9 assigned)
All codes come back after cycling ignition switch.
Can't use 'new' key as it is as yet uncut.
I am suspecting that EWS/DME needs to be re-sync'ed.

My apologies for the length of this post. My cables should arrive this week and I will be attempting to set up INPA. I appreciated the post in this thread re-assuring me that I can do no damage just looking around.

Side note unrelated Odometer reads 136,000 miles while EWS mileage reads 2,377,740 kilometers on AK90+ display. What's up with that?

Nice! On saturday I converted an e46 M3 from SMG to 6 speed manual, to where the whole car believes it is a manual (from its heart). Also coded out airbag errors for the installed Recaro seats and quick release steering wheel.


It is lights free and fully functional now

I thought I posted to this thread with a rather long winded rant describing my troubles with my 2001 Z3 3.0i. It has not appeared. Was it not acceptable?

That's way cool!

The only thing I don't like about coding is the sitting situation. I've thought about getting a USB extension cord so I could sit at my desk with the car out side wireless USB anyone?.....

Not sure what happened...
You can try again, and we can help!

That would sound cool, but extending a USB can cause problems with data stream, as well as bluetooth or wireless transmission; especially for jobs like the M3 SMG one where I used WinKFP to flash the ecu to the latest (March 2009) manual transmission software. Any break in communication and I risk bricking the ECU.



If it happens to be MSS54HP, then even used they can be over $300.



I AM super excited about a VW/Audi/Bentley/Lambo diagnosis and flashing cable that I have coming in, it has bluetooth, as well as USB connection, so at least I would trust wireless for diagnosis, maybe coding. Flashing? No way.

Any details of which specific file in the self extracting archive may be triggering it? This is a modified pack (added 32-bit NCSExpert, etc) of a pack that has been around for years... and I scanned the contents and the archives multiple times before uploading. No triggers from Housecall, Ad-aware, and malwarebytes, so for me that was good enough.

Scanned them all again and still nothing with mine.

Ran Malwarebytes on unzipped and compressed archives just now and still nothing. I would declare that a false alarm, as no issues have been reported... but it's up to you all, not me.

[MisterM52]

I wanted to Thank You for the guide but more so uploading the INPA files, in particular the INPA_502_Updated (INPA_502_Updated.rar) that I have been looking for all over the internet... hopefully your linkof INPA_502_Enabled_ReUpdated.zip does it for me, I am trying to install it on Win 7 Ultimate 64 bit.



- - - Updated - - -

Update, so I got the INPA software running, but it wont detect the car ignition on and the 2 dots keeps going up and down and it also wont communicate with the ECU. gives me these errors on both E36 and E34

[328 Power 04]

Check that the com port of the cable and the com port in the Ediabas obd.ini file match.

See the connection troubleshooting pdf I put up. It is in section E, number 3.

- - - Updated - - -

And, yes, this pack is a further modified version of the old 'INPA_502_Updated' that makes all the programs work on 64 bit, and in English for the most part. I updated old settings files as well.

I also went through the instructions and clarified things that caused issues.

F0 (240) Control unit fault, internal

Here is my question #1. What did MyAirBags do that I could not do with my C110 BMW code reader? Question #2. Would I have been able to accomplish what they did if I had had INPA up and running?

That error, error 240 is an actual hardware error with a resistor or chip on the airbag modules of that era. It was common on those, and BMW fixed the problem by releasing a new version of the module, with a completely new part number. My roadster developed that kiss-of-death fault when I replaced the seat belt tensioner with a used one from a newer Z3... I replaced the module with a used one from a forum member, and now it works fine. You cannot clear it with any diagnostics tools or software.

Under ABS DSC module:
5DF4 System voltage < 9 volts
5DF5 Internal fault control unit
5E1A CAN data error from DME/DDE (DSC lamp on until ignition reset)
5E26 Control unit, voltage supply, sensors

Solving this issue will allow titling of the vehicle.

Your DSC module probably needs to be rebuilt by modulemasters.com. It can happen on these, not unheard of. You can attempt to repair it yourself by opening the electronics side of the pump, inspecting all soldered connections for cracks and resoldering them. That is the main fix.

My last set of questions revolves around my stupidity. I purchased AK90+ to make additional keys for my two Z3's. As a person involved with electronic maintenance for decades, I should know better than to introduce new variables to an already puzzling situation.

Yes, first step is to try to resync ews to the dme with INPA. The AK90+ (chinese device?) may have either bricked the EWS3 module or at least reset it. It reading very different km may be proof that it is reading something wrong.



You understand how to use software and hardware, so you will enjoy using INPA much more than the C110 tool. It is much more powerful.

Luckily, it did not return, so far, after the module was RESET.

DUDMD got me past the 'no starter' condition by deleting the key #5 from the key list using the AK90+ ( yes a Chinese device). He also seems to believe that a re-sync of the EWS-DME will resolve the matter. I have my pc/INPA setup about 90% complete with cables for the USB port and FTDI chips with EDIABAS 5.7 and EDIABAS 4.4, NCS, SSS, WinFKP, etc. I am at the base of a very steep learning curve. I have looked at the opening pages of EDIABAS 4.4 and I hope you are right that is will be an enjoyable experience. I will let you know in the coming days. First task to perform, EWS-DME re-sync.

[328 Power 04]

They probably reflashed the module with chip programming tools or a bench flash. The module also locks itself with that error after a few airbag deployments. I have heard it was 3 deployments, bad enough to cause the module to record the data. It really only has space in the hexdump for maybe 3 crash data recordings. I will have to show you a screenshot of a clear one and an example I found with a few crash recordings.

I had spent some time and money when my airbag module went, with a CarProg 7.28 clone tool. It read my other cars' airbag modules, and I could reflash them, but not this one. It would not read or respond at all.
