Normal Operation

When the ignition is in the ON position, the passenger air bag deactivation (PAD) indicator prove-out period is initiated by the restraints control module (RCM). The RCM briefly activates the PAD indicator to verify to the occupants correct functional operation of the PAD indicator. See AIR BAG AND SAFETY BELT PRE-TENSIONER SUPPLEMENTAL RESTRAINT SYSTEM (SRS) , .

If the RCM detects a short to battery on the PAD indicator circuit, it will store diagnostic trouble code (DTC) B1890 in memory and illuminate the air bag indicator.
