PINPOINT TEST 3: DTCS B1884 - PAD WARNING LAMP CIRCUIT FAILURE

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 PRETENSION ER SUPPLEMENTAL RESTRAINT SYSTEM (SRS).

If the RCM detects an open or short to ground on the PAD indicator circuit, it will store diagnostic trouble code (DTC) B1884 in memory and illuminate the air bag indicator.

Possible Causes
A PAD indicator circuit open or circuit short to ground can be caused by:
- damaged wiring, terminals or connectors.
- a faulted PAD indicator.
- a faulted RCM.

NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough Inspection and Verification before proceeding with the pinpoint test.
