Lamp Fault Codes (LFCs)







The lamp fault codes (LFCs) indicate the specific flagged faults associated with diagnostic trouble code (DTC) B2294.

Normal Operation

NOTE:
- There are 2 different safety canopy modules. The early build safety canopy module has 2 fasteners and a hook retainer that attaches onto the roofline sheetmetal at the B-pillar, the late build safety canopy module will not. The early build and late build safety canopy modules are not interchangeable.
- To identify between an early build and a late build vehicle, inspect the driver safety canopy module. The late build vehicle has a bracket located at the C-pillar, the early build will not.

Safety canopies are designed to provide occupant protection during a side impact or in the event the vehicle rolls over.

The restraints control module (RCM) checks all safety canopy module circuits for faults. If the RCM detects one of the following faults on any module circuit, it will store diagnostic trouble code (DTC) B2294 in memory and, depending on the fault, flash a lamp fault code (LFC) on the air bag indicator.

Fault Conditions
The RCM monitors for the following fault conditions:
- low resistance.
- high resistance or circuit open.
- circuit short to voltage.
- circuit short to ground.

Possible Causes
A module fault can be caused by:
- faulted wiring, terminals or connectors.
- a faulty safety canopy module (if equipped).
- a faulted RCM.
