Lamp Fault Codes (LFCs)







The lamp fault codes (LFCs) indicate the specific faults associated with diagnostic trouble codes (DTC) C1414

Normal Operation
The restraints control module (RCM) monitors the communication condition and circuits of the impact sensors and the OCS system for an embedded vehicle I.D.

If the RCM receives conflicting information from the impact sensors or OCS system it will store DTC C1414 in memory and, depending on the fault, flash a LFC on the air bag indicator.

Possible Causes
An incorrect vehicle identification code can be caused by:
- incorrect RCM for vehicle.
- incorrect impact sensor information.
- incorrect OCS system for vehicle.
- wiring, terminals or connectors.
