Normal Operation
CAUTION: The passenger air bag deactivation (PAD) indicator is part of integrated control panel (ICP) assembly and cannot be separately serviced. Installation of an incorrect ICP may cause a fault in the supplemental restraint system and illuminate the air bag warning indicator in the instrument cluster.
When the ignition is in the on position, the PAD indicator prove-out period is initiated by the RCM. The RCM briefly activates the PAD indicator to verify to the occupants correct functional operation of the PAD indicator.
If the restraints control module detects an open or short to ground on the PAD indicator circuit, it will store diagnostic trouble code (DTC) B1884 in memory and flash lamp fault code (LFC) 18 (or higher priority code if one exists) on the air bag indicator.
Possible Causes
A PAD indicator circuit open can be caused by:
- wiring, terminals, or connectors.
- incorrect integrated control panel (ICP) (not equipped with PAD indicator).
- a faulted PAD indicator.
- a faulted RCM.
