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 and no air bag fault exists. The air bag indicator will remain illuminated continuously after five 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 air bag indicator circuit can be caused by:
- damaged wiring, terminals, or connectors.
- a faulted RCM.
- a faulted instrument cluster module.
