Race Seat Coding

Has anyone figured out how to get rid of the errors and not plug in the factory seat buckles. I've coded out the airbags, etc... but I can't get the restraint malfunction to go away unless I plug in the seat belt buckle connector.

These are all coded and seem to work.

Occupancy sensor:
CIS_Beifaher: aktiv -> nicht_aktiv

Driver seat airbag:
Sitzairbag_Thorax_Fahrer: aktiv -> nicht_aktiv

Passenger seat airbag:
Sitzairbag_Thorax_Beifahrer: aktiv -> nicht_aktiv

Passenger seat position sensor:
Sitzpositionsensor_Beifahrer: aktiv -> nicht_aktiv

Driver seat position sensor memory:
Sitzpositionsensorserkennung_Sitzmemory_Fahrer: aktiv -> nicht_aktiv

Got it.

Code the following

Gurtstrammer_Fahrer ->nicht_aktiv (belt tensioner driver driver)
Gurtstrammer_Beifahrer ->nicht_aktiv (belt tensioner driver passenger)
Gurtkontakt_Fahrer ->nicht_aktiv (belt contact driver driver)
Gurtkontakt_Beifahrer ->nicht_aktiv (belt contact driver passenger)
Gurtzustandsanzeige_Fahrer_GWF_GZA_FA ->nicht_aktiv (Belt condition indicator driver driver)
Gurtzustandsanzeige_Beifahrer_GWF_GZA_BF ->nicht_aktiv (Belt condition indicator driver - passenger)
Abschalten_Fehlerqualifikation_Plausipruefung_dyn_ Daten_FGS->nicht_aktiv
(Shutdown Error qualification Plausibility error)

No, I don't believe BimmerCode supports 'Expert Coding' on ACSM Module.

This would be done on E-SYS.

My friend used a 3,6 ohm resistor and deleted the fault codes on his M2. Done. I will try on my M4 on Friday.

So other than coding the FDLs and writing them to the ACSM module did you have to code any other modules? The reason I ask is that I have done as you suggested but I'm still get restraint malfunction errors.

If anyone needs assistance with coding this out, I'd be happy to help via TeamViewer.

I tried to install the seats in an 2020 F87 M2 Comp today, and seems like no matter what I do, I can't code out one restraint system error.

I only have the driver seat changed right now, was making sure I can code everything before changing the passenger seat.

I have the factory belt buckle on, the connector is connected correctly, because if I remove the connector I get a secondary code.

I tried to clear all the codes with tool32 but one won't clear.

So far I coded all the following:

Occupancy sensor:
CIS_Beifaher: aktiv -> nicht_aktiv

Driver seat airbag:
Sitzairbag_Thorax_Fahrer: aktiv -> nicht_aktiv

Driver seat position sensor memory:
Sitzpositionsensorserkennung_Sitzmemory_Fahrer: aktiv -> nicht_aktiv

Coded all the memory settings to nicht_aktiv as well.


I even tried what bracer posted, but never was able to get rid of this last restraint error.

Any help would be appreciated.

Yeah I did.

So I hope this post helps someone in the same situation in the future. I have seen a few people with similar problems to what I was having trying to find a solution.

No matter what was coded as "Nicht Aktiv" there would still be one error for a restraint system, even with the seat belt buckle connector plugged in correctly. Also Tool32 would not be able to erase it.

I coded the car back to factory coding then coded out the same things that was discussed in this thread, cleared the existing codes that popped up with tool32, voila, magically no more errors.

Ah yes, you had a latched fault that needed to be cleared. You could have used ISTA to clear it I bet.

I guess I need to learn to use ISTA

Is ISTA a free to use program?

Sorry if this is a dumb question. Does the steering wheel and front pass airbags still go off in a collision if the codes above are executed? Thanks all!

Hey Guys, i have a 2016 M3, if i buy these seats, will i be able to code out all the dash lights but still keep my air bags functioning?

I'm looking at doing driver and passenger so i can run harnesses for the track.

I've tried this and having the exact same problem, funny thing is if I swap over the connectors or rotate them I go from having the generic restraint error to driver/passenger restraint erorr.

Anyone else shine any light on this I tried all the above parameters plus more but having this issue - F87 M2 Competition

Assuming all of the coding from above is correct, did you try using ISTA to clear any air bag/restraint faults? Tool32 was mentioned above for fault clearing purposes. I am not an expert on Tool32, but I do know it is an older BMW diagnostic tool as ISTA is the current BMW dealer diagnostic tool of record. Since the F87 is a very new'ish BMW, Tool32 may not be working properly for the F87 due to the age of the tool.

If that is not the case (i.e. ISTA could not clear the fault), then there could be some software/coding differences between the F87 and the F80/82. Despite the obvious similarities between the M2 and the M3/M4, this would not be the first time there is a software/coding difference that causes issues like this. If all else fails, you may need to hit up a paid coder as there are still some coding "trade secrets" they keep to themselves.
