Normal Operation
During normal operation, the air bag indicator will illuminate continuously for approximately 6 seconds and then go out after the ignition switch is placed to the ON or START position and no air bag faults exist. The air bag indicator will remain illuminated continuously after 5 cycles of a lamp fault code (LFC), if a fault exists.

If the restraints control module (RCM) detects an open or short to ground on the air bag warning indicator circuit, it will store diagnostic trouble code (DTC) B1869 in memory.

Possible Causes
An open or shorted air bag indicator circuit can be caused by:
- wiring, terminals or connectors.
- a faulted RCM.
- a instrument cluster module internal concern.
