B1884

DTC B1884 / LFC 27 - PASSENGER AIR BAG DEACTIVATION (PAD) SWITCH WARNING LAMP INOPERATIVE

Normal Operation
The restraints control module (RCM) has the ability to deactivate the passenger side air bag under certain conditions. When the passenger air bag is deactivated, the passenger air bag deactivation (PAD) switch warning lamp will be illuminated.

The RCM monitors the PAD switch warning lamp for open or short to ground conditions. If the RCM detects an open or short to ground condition on the PAD switch warning lamp circuit, it will store a diagnostic trouble code (DTC) B1884 in memory and flash a lamp fault code (LFC) 27 (or higher priority code if one exists) on the air bag indicator.

Possible Causes
- an open or short to ground on (Y/LG) wire.
- a damaged or burned out PAD indicator.
- a damaged or inoperative PAD lamp.
- a faulted RCM.
- blown I/P fuse panel fuse.

WARNING: If the supplemental restraint system (SRS) is being serviced, the system must be deactivated and restraint system diagnostic tools must be installed.

The air bag restraint system diagnostic tools must be removed and the air bag modules reconnected when the system is reactivated to avoid non-deployment in a collision resulting in possible personal injury.

WARNING: Never probe the connectors on the air bag module. Doing so can result in air bag deployment, which can result in personal injury.

WARNING: The safety belt pretensioner is a pyrotechnic device. Always wear safety glasses when repairing an air bag equipped vehicle and when handling a safety belt buckle pretensioner or safety belt retractor pretensioner. Never probe a pretensioner electrical connector. Doing so could result in pretensioner or air bag deployment and could result in personal injury.

NOTE: After diagnosing or repairing an SRS, the restraint system diagnostic tools must be removed before operating the vehicle over the road.

NOTE: The SRS must be fully operational and tree of faults before releasing the vehicle to the customer.
