Diagnostic Routine A


13. CHECK THE DRIVER FRONTAL STAGE 1 DEPLOYMENT CONTROL DTC (Diagnostic Trouble Code) FOR A FAULT STATUS CHANGE (SHORT TO GROUND INDICATED) (CLOCKSPRING DISCONNECTED)

NOTE: This pinpoint test step attempts to change the fault reported by the RCM (Restraints Control Module) by inducing a different fault condition. If the reported fault changes, this indicates the RCM (Restraints Control Module) is functioning correctly and is not the source of the fault.
