Title: Airbag ECU swap
Post by: omegod on 06 August 2020, 21:50:54
Helping a local chap out who has airbag light lit, scanned it and code showing as " Replace airbag ECU" which won't clear so it's fubarred.  I've done  a swap before but can't remember if it needs to be identical model like the ABS ecu, donor ecu is from a 2.5 facelift estate going in into 2.2 saloon. There's a fair of trim removal involved to get to the bugger so I don't want a headache if it's avoidable  ;)

I swapped one last year because the passenger child seat sensor was faulty so changed the ECU for an older model pre this functionality with no issues. Not sure of the situation between the two models you mention.

As long as both cars have side airbags and seat belt pretensioners, it should be fine. Ideally part number and code should match, but post '98 should be sufficient.

Stripping the centre console is barely a ten minute job...

It is indeed when stripping an ecu out of scrapper but getting it back together and looking presentable without breaking aged plastics on someone's car is a longer process, part of you response is very much appreciated but as I didn't ask for a critical analysis of a process please feel free not to provide one in future

It needs to be an *IDENTICAL* spec car, with regard to SRS.  So airbag config and sensor config (including occupancy sensors) need to be the same.

Usual reason for a Replace ECU with SRS is that the SRS has deployed.  This means checking if other components need replacing before putting in a new ECU.

You use the scrapper to figure out how to disassemble the console.
