Test B: DTC B1869 - Lamp Air Bag Warning Indicator Circuit Open Or Short To Ground
PINPOINT TEST B: DTC B1869 - LAMP AIR BAG WARNING INDICATOR CIRCUIT OPEN OR SHORT TO GROUNDNormal Operation
During normal operation, the restraints control module (RCM) will illuminate the air bag warning indicator 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 warning indicator will remain illuminated continuously after 3 cycles of a 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 RCM detects an open or short to ground on the air bag warning indicator circuit, it will store DTC B1869 in memory and sound the secondary air bag warning.
- DTC B1869 Lamp Air Bag Warning Indicator Circuit Open or Short to Ground - If the RCM detects an open circuit or short to ground when the indicator is not active, it will set this DTC.
