Lamp Fault Codes (LFCs)







The lamp fault code (LFC) indicates the specific fault associated with diagnostic trouble code (DTC) B1890:

Normal Operation
When the ignition is in the ON position, the PAD indicator prove-out period is initiated by the restraints control module (RCM). The RCM briefly activates the PAD indicator to verify to the occupants correct functional operation of the PAD indicator.

If the RCM detects a short to battery on the passenger air bag deactivation (PAD) indicator circuit, it will store DTC B1890 in memory and flash LFC 10-14 on the air bag indicator.

Possible Causes
A PAD indicator circuit short to battery can be caused by:
- wiring, terminals or connectors.
- a faulted PAD indicator.
- a faulted RCM.
