Did you remove an airbag and are trying to code it out? or did you replace it and just need to shut the light off?

What are the faults code?

 

I had to replace both the steering wheel airbag + the indash passenger airbag, plus i was advised the module is kaput after an airbag deployment, so i got a used one from clemster, but never got around to coding it. Now that im trying, I’m not understanding the process of how to code with ncs expert. I cant get inpa to connect to the airbag system either to retrive codes

 

Inpa not connecting is suspect, if it can't connect then I'm pretty sure you won't be able to code it. if the module isn't responding it indicates a power, can problem or module issue not a coding issue. You'll need to be able to connect before you can push the coding.

 

I used INPA to reset my airbag light, not sure you can do it with NCS Epert

Yeah me just clarify if you're resetting the light inpa/ista is the way to go. If you're looking to change it ie you removed an airbag, want to enable the rears removed the seat pretensioners ect then you code it.

 

So here is a quick coding write up, I was doing something up and figured I'd grab some data

1)NCSExpert Loading coding profile
2)Vin->ZCS/FA -> I choose EWS but IKE works too
3)Back to main
4)Process ECU Choose ABG
5)Change Job
6) Cideuerdaten_lesen
7)Execute Job

Modify the file

8)Change the SG_CODIEREN
9)Execute

Clear fault codes if needed.

 

Isn't it different if it's a used module or definitely one that's been involved in a crash incident? The old VIN has to be overwritten first and if in an accident, hard coded event data erased.

 

Shouldn't matter once he gets it communicating you can use tool32 to sync vin and clear out the history, assuming it cares. I'd have to look to be honest but it's all moot until it's talking.

 

Ok, so From what I've gathered through this thread, I may not have to code the module, but first I need to get it talking. Im going to start my troubleshooting tomorrow to figure out where my INPA issue is first, then Update.

 

Ok, I have quite a few codes, but I also have an issue. When I tried to clear to codes to have a fresh slate, I received a Job Status error[ERROR_ECU_REJECTED] instead of [OKAY]. I also see that I have the internal ecu error #240? Maybe I got a lemon replacement ecu?

 

I assume this is your old module? Also can you run ident so we know which one you're dealing with.

 

I’ll run ident as soon as I get home today. I know i was reading the module information, and the date of manufacture was 14/99. My car is a 02/00. Maybe the software is different?

 

Sorry I missed it early is the scanned module the original or the one you bought second hand?

 

Thats the second hand one. Original I already threw out several months ago cause I thought it was ruined
