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 in the ON or START position and no air bag faults exist. The air bag indicator will remain illuminated continuously after 3 cycles of a lamp fault code (LFC), if a fault exists. Be sure to cycle the ignition switch and look for an approximate 6 second indicator prove-out without LFCs.

If the restraints control module detects an open or short to ground on the air bag warning indicator circuit, it will store diagnostic trouble code (DTC) B1869 in memory. If any other DTCs are detected with this DTC active, the secondary air bag warning will be activated.

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