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

P1-P4:

Normal Operation
The instrument cluster sends a reference voltage to the restraint control module (RCM) through circuit 608 (BK/YE). The instrument cluster illuminates the air bag warning indicator when it receives an open (no ground) from the RCM on circuit 608 (BK/YE). The instrument cluster turns off the air bag warning indicator if it receives a ground signal from the RCM on circuit 608 (BK/YE).

Possible Causes
- RCM
- Instrument cluster
