When the ignition switch is in the ON position and the system supplied with current, the control module carries out initial self-diagnosis for a maximum
of 10 seconds. As a safety measure, the airbags cannot be activated during this period.
The electric detonators and the wiring, power supply, airbag warning lamp, microprocessor and side impact sensors are all checked during this
self-diagnosis.
The airbag warning lamp lights up during the first test when the current is turned on for 3-4 seconds to check the lamp. Self-diagnosis then continues for
as long as the ignition switch remains in the ON position.
There are 41 diagnostic trouble codes covering all sensors, wiring harnesses, airbags, seat-belt tensioners and internal control module faults.
The control module can measure shorting to ground and B+ as well as resistance for low and 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.
