When the ignition is in the ON position and the system has power, the control module runs on-board diagnostics for 3.5 seconds. As a safety precaution,
the airbags cannot be triggered during this time.
The following are checked during the self-test: electric detonators with wiring harness, power supply, airbag warning lamp, microprocessor, side impact
sensors and front impact sensors.
Upon supply of power, the airbag warning lamp lights during the first test for 3-4 seconds to check the lamp. On-board diagnostics then continue as long
as power is supplied. The airbag warning lamp has no diagnostics.
There are DTCs in the system to cover all sensors, wiring harnesses, airbags, seatbelt tensioners and internal control module faults.
The control module can measure shorting to ground and B+ as well as resistance too low and too high in all ignition circuits. In case of a system
malfunction, the Airbag warning lamp is illuminated.
The control module monitors the diagnostic trouble code conditions at different intervals, depending on the diagnostic trouble code concerned.
