PINPOINT TEST Q: THE AIR BAG WARNING INDICATOR IS NEVER/ALWAYS ON

Q1-Q2:

Q2-Q4:

Normal Operation
The air bag warning indicator provides an indication that there is a restraint system problem and the air bag may be inoperable or have degraded performance. If the instrument cluster does not receive the restraint control command over the communication network, the instrument cluster illuminates the air bag warning indicator.

DTC B1868 - is a continuous DTC that sets if the instrument cluster detects an internal circuit failure in the air bag warning indicator and warning indicator circuitry. When a fault is detected in the primary air bag warning indication, the instrument cluster sets DTC B1868 and defaults to the secondary warning and the air bag warning chime sounds.

Possible Causes
- Restraints control module (RCM)
- Instrument cluster
