    HOW TO: Reset Early Airbag/SRS light. No Special Tools!!!

    This only works on Early E31, start of production to 09/93 With SIEMENS 5WK4 027 (65771382905) modules. This module is also found in some E23,e24,e30,e32,e34, and e36, procedure should work for those as well. This worked for mine even when DIS/INPA/Autologic, and all those others failed to communicate.


    1. Turn the ignition switch to the off position.
    2. Install a jumper from in pin #15 of the engine diagnostic connector to
    ground.(Since this is awkward to do in the timing given in this procedure, i used a small screwdriver and tapped into pin 6 at the orange x74 connector behind the glovebox, either will work)
    3. Turn the ignition switch to the on (run) position but, do not start the car.
    4. wait five seconds
    5. disconnect the jumper.
    6. Wait another five seconds.
    7. Reconnect the jumper
    8. After five seconds
    9. disconnect the jumpers.
    10. Wait five seconds
    11. Turn the ignition switch off.
    12. Start the car. The air bag warning light should clear after approximately 10
    seconds. If the light does not clear repeat the procedure. If, after three attempts,
    the light does not clear, there is most likely a problem with the air bag system
    which needs to be repaired.

    6. Reconnect the jumper to ground pin #6 (or from pin #15 in the round OBD port under the hood???).
    7. After five seconds, disconnect the jumpers (I'm assuming you mean only one jumper either Pin #15 of the round OBD port under the hood, OR the alternative Pin #6 of the orange x74 connector behind glove box, and not 2 jumpers?.
    Legoman, can you see what I wrote in color and clarify for me please. Just wanna make sure there is only one jumper wire needed.
    either the #15 pin in the round OBD port under the hood, OR the alternative pin #6 of the x74 orange connector under glovebox.
    Cheers

    I remember doing something with a wire and the OBD port to reset the oil/service interval light too.

    i found it in an old PDF file that was for another car, i just modified it slightly to correct the pin numbers and plugs.

    Send me the instructions you have, maybe I can translate (electrially).
    It would be great to do this kind of thing with a $1.49 16-pin PIC microcontroller, a $0.49 7-segment display, and a $0.75 1"x1" piece of proto board.

    After start up the SRS light on my car (CB42262 Prod 02/91) blinks for about two-3 minutes and then stays on permanently while the car is running...is it supposed to? If not should I give this a try? I presume the light should be off.

    Off -topic- sort of? I got a nice tutorial from Iceman (Brian) and he demonstrated his diagnostic tools on friday in Wichita. He used his tools to help me diagnose a potential cause of my rich running passenger bank. Great guy! I have a better idea of how DIS/INPA work...and am curious about crankshaft rotational information. How can we M70 owners get more diagnostic info about (cylinder specific) the crankshaft dynamics. The "rough" crankshaft information. Just curious!

    The light should not stay on. It should go off within 10 seconds of the car starting.

    Remaining on means there is a fault code stored in the module. Most likely from removing the steering wheel without taking proper steps to avoid triggering it. This procedure should work for you.

    Thanks ...its on my list. I have larger "cats to skin" at the moment(e.g. finish putting in air collectors, front UCA's rear ball joints...etc). I am on my way home to CLT. Glad I took the car...for Wuffer's sake it is gonna be my daily driver!

    Aside: After Iceman(Brian cleared codes with his DIS/INPA) and we drove the car for awhile I had 1444(ok) and 2247. Today I have 1247 and 2247. Car is running on all 12 ...new sparkplug set new d side MAF and water temp sensor. Need to swap O2 sensor leads. Lots of smoke on startup out right side exhaust and definitely running rich on that side...conclusion was that O2 sensors may have been swapped and the EML (?) is trying to compensate and is adjusting fuel/air mixture of the throttle bodies...throttle bodies were refurbished by Tom Carter. Brian introduced me to Gerry Veer who was looking for the BMW procedure to adjust the wipers in the DK rotors before reinstalling them. Seems like I saw a thread here related to that....Ilike your wheels on your car. I bought some 17 inch used TSW Hockenheim's and new tires and will be installing those when I get back to CLT. Thanks for the procedure. I want to make a trip out west in my 8...so it would be great to meet up sometime!

    This is very timely as my SR light just started blinking. Can one of you post a diagram of engine diagnostic connector or the one behind the glove box or some pictures showing the jumpers please? My production date s 05/93 so this should work. We have had our old girl or over 20 years, drive it daily. I appreciate your help very much. PAH850Ci in Dallas.

    the X74 plug is an 8 pin orange plug that plugs into the SRS module(1 of 2 that plug into the module, the other is a 6 pin). the module is located behind the glove box. You have to remove the kick panel, under tray, and upper and lower glove boxes to get to it. Unless your dash is already a part, or you are familiar with removing the glove box, i would just get a buddy to work the ignition for you while you do the jumper from the diagnostic plug pictured above.

    - - - Updated - - -

    Also in response to earlier posts about reading the codes. It doesnt actually state how to trigger the blinking, it just says it can be done:

    You can retrieve the fault codes from a Siemens controller if you wish. The controllerwill blink out a series of codes through the SRS light in the Active Check Control panel.
    The first number that it blinks is the number of stored codes. Next, will come a long
    blink. Then the fault codes will be blinked. The fault codes are separated by a long
    blink. Each fault code is blinked as four digits as follows:
    1. Light flashes 1 to 4 times for the first digit.
    2. 3 second pause.
    3. Light flashes 1 to 4 times to indicate the second digit.
    4. 3 second pause.
    5. Light flashes 1 to 4 times to indicate the third digit.
    6. 3 second pause.
    7. Light flashes 1 or 2 times. (once = Short-time fault; twice = Long-time fault)
    The table below provides the fault descriptions for early Siemens controllers
    Here is the table:

    Blink Code-Fault-Fault Description
    111 1 Front Sensor Left Closed 1 time
    211 2 Front Sensor Left Closed several times

    I am still working on reading codes, the instructions i found for that are not clear. I will update with that later.
    Here is what I know:
    My 1990, E34 M5 has the same SRS control unit. My 1988, E24, M6 had an earlier model Siemens SRS controller that uses the same code reader/reset tool.
    I purchased the BMW SRS code reader/reset tool (88 88 6 621 290) that works on the Siemens SRS controller a long time ago because it was the only way to reset the Siemens SRS control in the early days (1990's).
    The Siemens SRS control causes a lot of consternation when it was first introduced because it was the first SRS control that required special tools to reset.
    Yours is the first post since I have been involved with BMWs since 1990 that indicates the Siemens SRS controller can be reset without special tools.

    As for reading the SRS flash codes; there are only 2 document that I am aware of, produced by BMW, that explain how to read the flash codes and only one document that defines the flash codes.
    The manual for the 62 1 290 SRS reader/reset tool only has the explanation of how to read the SRS flash code.
    The E30 Repair Manual (01 51 9 770 561) includes the SRS Troubleshooting in the Group 32 Steering and Wheel Alignment section.
    https://www.bmwtechinfo.com/repair/main/Index_cd3.htm
    This manual on page 32-55.1 includes the Siemens SRS Control - HOW TO Read the SRS light flash codes and a section on flash code conversion into fault codes and fault code definitions.

    The SRS flash/fault code list posted here is a more comprehensive list that what is in the E30 Manual and includes SRS codes I have yet to find in any other official BMW document and believe me I have just about every official document produced by BMW.

    The BMW OE reset tool 62 1 290, for the SIEMENS 5WK4 027 (65771382905) controller also works with the Siemens controller in the E23, E24, E28, E30, E31, E32, E34 & E36 vehicles up to 9/1991. Some of these cars also used a Cipro airbag controller but I believe the E31 only used the Siemens SRS controller.

    On the E31 this model Siemens controller was also only used up to 9/1991. Unsure what controller is used after 9/1991 , however the Peak R5/SRS scan/reset tool works on my 97, 850
    It is also my experience that the Peak R5/SRS scan/reset tool is unfortunately not compatible with the Siemens 5WK4-025,027 or 035 controller.

    Question on this? I've read that pin 19 is ground so it stands to reason that you could use the jumper to connect pin 15 and pin 19 and that would work?

    the later airbag modules (09/93 and up from what ive read) have no issues communicating with all the usual diagnostic tools(DIS, INPA, Autologic, PEAK, ETC).

    The only 2 units i have heard of that will reset the early 5WK4 airbags are the factory tool you mentioned, and shogun's specially developed tool.

    didn't work on my 04/1991 850i
    And the system should be ok because there was no issue before I swapped the wheel.

    The timing is very specific. I actually used the stopwatch on my phone to do it.

    Wolf, in case you need, I have some BOA on stock, that definitely works on your E31.all BMW from 1987-2006, plus Mini and Rover from 2001 for airbag/srs/oil/inspection/annunal inspection (clock), has connector for 20-pin round diagnosis port plus OBD

    I ordered the tool from shogun and succeeded on two 850s. My own one plus a customer car having had the same issue like me.
    Also the SI rest works flawlessly. Thanks for pointing me to that product Erich.

    Hey guys.
    I was wondering about one thing.
    I changed the steering wheel to a non airbag one and have the airbag light on.
    Got the reset tool from Shogun. Has anyone been in this situation? Will it take the light out?

    The reset tool will be shipped to you this week, but in my opinion you will not be able to permanently reset the airbag light, as the airbag module has the fault that the steering wheel airbag is missing, not working ot whatsoever. I either will go out when resetting, but will go on again when you start the car or it will not go out at all. My tool is not to trick the airbag system, it is just to reset the airbag light after a fault has been repaired.
    The owners manual for the reset tool clearly mentions:
    Note: the SRS system on your BMW needs to be functioning properly in order to reset the airbag/SRS light. If the system detects a fault on any of the systems sensors a reset without replacement/repair of those failed components is not possible.

    I assume the only possibility might be to simulate that the steering wheel airbag is still there, at your own risk of course. Maybe similar to the seat mat occupancy sensor simulator for the passenger seat. Often the sensor mat is defective and the light comes on and people install this simulator under the seat.
    But I have no idea how such a simlator for the steering wheel airbag should be.

    Update:

    I figured I'd try one last thing.
    So I made this little jumper with a switch and connected it to pin 15 (RXD) and pin 19 (ground).



    Then I followed this procedure using my stopwatch app on my phone.

    HOW TO: Reset Early Airbag/SRS light. No Special Tools!!!

    This only works on Early E31, start of production to 09/93 With SIEMENS 5WK4 027 (65771382905) modules.
    This module is also found in some E23,e24,e30,e32,e34, and e36, procedure should work for those as well.
    This worked for mine even when DIS/INPA/Autologic, and all those others failed to communicate.


    1. Turn the ignition switch to the off position.
    2. Install a jumper from in pin #15 of the engine diagnostic connector to ground.
    3. Turn the ignition switch to the on (run) position but, do not start the car.
    4. After five seconds, disconnect the jumper.
    5. Wait another five seconds.
    6. Reconnect the jumper
    7. After five seconds, disconnect the jumpers.
    8. Wait five seconds after disconnecting the jumpers.
    9. Turn the ignition switch off.
    10. Start the car.
    The air bag warning light should clear after approximately 10 seconds.
    If the light does not clear repeat the procedure.
    If, after three attempts, the light does not clear, there is most likely a problem with the air bag system which needs to be repaired.
    IT WORKED!

    The SRS light solidly came on with the ignition and then went out. Silly me, I saw this process a while ago and dismissed it since I read everywhere that you needed special tools and software to talk to the SRS module.

    I'm still in WOW, I can't believe it mode.

    cheers
