Diagnostic Fault Information
Circuit/System Description
During a frontal crash of sufficient force the inflatable restraint sensing and diagnostic module (SDM) will allow current to flow through the
deployment loop in order to deploy the driver steering wheel air bag. The SDM performs continuous diagnostic tests on the deployment loops to
check for proper circuit continuity and for shorts to ground or voltage. There are 2 shorting bars used within the driver steering wheel air bag coil
connector which will short together both driver steering wheel air bag stage 1 control circuit and driver steering wheel air bag stage 1 control circuit
and both driver steering wheel air bag stage 2 control circuit and driver steering wheel air bag stage 2 control circuit when the connector is
disconnected. This will help to prevent unwanted deployment of the air bag during servicing.
Conditions for Running the DTC
Ignition voltage is between 9-16 V.
Conditions for Setting the DTC
B0012 01 stage 1 or B0013 01 stage 2
The driver steering wheel air bag control circuit is shorted to voltage for 2 seconds.
B0012 02 stage 1 or B0013 02 stage 2
The driver steering wheel air bag control circuit is shorted to ground for 2 seconds.
