Airbag ECU ‘missing’ in UCH config - light still on

[HSH]

This has left me scratching my head.
With the ecu ‘present’ I reset everything to ‘without’ whilst all sensors/airbags were disconnected.

Then disconnected the ecu, set it to ‘missing’ on the UCH install list. Ran a multiplex test and no faults found; ie no ‘airbag ecu not found’ fault. Winner..

However the airbag light is still illuminated.

My last thought is maybe my UCH cannot accept such configs? Or am I being thick and missed something obvious?

Leave airbag ecu fitted or tape the light.

This is a work around I am aware of although with Clip at my disposal I’d rather a proper fix. I am contemplating leaving the ecu in, as it weighs nada

I believe pulling the ecu will always throw the light on even when turned off in the multiplex. I just left the airbag ecu in with the airbags disabled and no warning lights.

Yeah, I also believe the airbag ECU has to remain plugged in.

Deffo AB ecu has to remain in the car

This isn't how you turn it off you have to go into it and turn the stuff off in it, not just the module.

Hi mate

Did you ever get to the bottom of this? I'm trying to code everything out on my 182 and have got everything set to "without" and managed to erase all Fault Codes, but still have the warning light coming on.

Cheers.
