Instructions to Reset Airbag Warning Light

Model: Mercedes Classe M W163 - Years 1997-2005
Part: Warning light – error code

If the airbag system warning light (SRS) remains illuminated on the instrument cluster display after the self-check, you need to use a diagnostic tool to verify the nature of the fault and simultaneously check the type of fault stored in the control unit located at the front of the centre tunnel, just in front of the gear lever. Connect the tool to the OBD port, select the make and model of the vehicle, and enter the diagnostic section, particularly the body computer, and read the error codes: the system detects an anomaly in the resistance value of the left side airbag deployment device, that is, the one in the door (it could be a loose connector). Then proceed to clear the fault memory.
