Test B

PINPOINT TEST B: DTC B1869 - AIR BAG WARNING INDICATOR CIRCUIT OPEN OR SHORT TO GROUND


Test B1:






Test B2-B3:






Test B3-B4:






Test B5-B6:






Test B7-B8:






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 fault exist. 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 or shorted air bag indicator circuit can be caused by:
- faulted wiring, terminals, or connectors.
- a faulted RCM.
- an instrument cluster module internal concern.
