So you're only talking to the engine ECU, nothing else.Īnnoyingly, the airbag ECU isn't on pin 7, it's on pin 3. Most people use these OBD key / KKL (vag-com style audi) cables for diagnostics but they only talk to the engine which is on the K-line pin 7 of the connector. You'll need some software that can connect to the ECU and you'll need either a modified diagnostic cable or an adapter cable. ![]() Sadly, resetting these systems isn't straight forward either. I'm not sure if it even shuts down the airbag system when it picks a fault so in even of an accident you'll get nothing - hazards of working with explosives I guess. The airbag ECU doesn't do this - fault detected, even if just for a brief moment, will pop the light on and remain on. The engine ECU if it throws a fault light will put the engine light on, but if after around seven engine starts the fault has not been present it'll remove the warning light but keep the code stored. ![]() You'll find with these ECUs that they don't clear the fault light if the fault disappears like the engine ECU might. ![]() I'm pretty sure that the Stilos use the same airbag systems as the Alfa's I've experienced previously - the allied MY99 (maybe MY97 in earlier cars).
