B1932
DTC B1932 / LFC 32 - DRIVER AIR BAG RESISTANCE HIGHThe restraints control module (RCM) monitors the resistance for the driver air bag ignitor by measuring the resistance between pins 3 and 4. If the RCM detects high resistance between these pins, it will store a diagnostic trouble code (DTC) B1932 in memory and flash a lamp fault code (LFG) 32 (or higher priority code if one exists) on the air bag indicator.
Possible Causes
Driver air bag high resistance could be caused by:
- a poor connection or corrosion in the driver side air bag module circuits or the air bag sliding contact.
- an open circuit or high resistance in the air bag sliding contact windings.
- wiring, terminals, or connectors.
- an open circuit or high resistance in the driver side air bag module.
- a faulted RCM.
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.
