Supplemental Restraint Systems

Faults

If you have the fault code for a defective ACM and this is amongst other fault codes, then it could be a spurious code. Some modules do display this code until the other active faults have been rectified. This is particularly common with Hondas, Renault, Vauxhall, Peugeot and Citroen. You should work through the other fault to see if you can eliminate them. If you'd like to test the airbag module you could disconnect a known working component like a seatbelt pre-tensioner/crash sensor or airbag and it should introduce a new fault code to the modules memory, if it doesn’t and the other fault codes don’t seem to correspond to the damage or repairs then you may suspect the airbag module at fault.
