Lamp Fault Codes (LFCs)







The lamp fault code (LFC) indicate the specific fault associated with diagnostic trouble code (DTC) B2792.

Normal Operation
The restraints control module (RCM) monitors all deployable devices for a cross link fault between circuits. If the RCM detects a short between any of the deployable circuits, it will store a diagnostic trouble code in memory, flash LFC 12-11 on the air bag indicator and the secondary air bag warning chime will be activated.

Possible Causes
A cross link fault between air bag modules and safety belt pretensioners can be caused by:
- wiring, terminals or connectors.
- a faulted RCM.
