Normal Operation
The restraint control module (RCM) is hardwired to the instrument cluster through circuit 31S-JA14 BK/GN). When the RCM detects a system concern, DTC is set and the RCM removes the ground to the instrument cluster to turn on the AIR BAG warning indicator. RCM DTC B1869 is set if circuit 31S-JA14 (BK/GN) is open or shorted to ground. RCM DTC B1870 is set if circuit 31S-JA14 BK/GN) is shorted to power.
Possible Causes
- circuit 31S-JA14 (BK/GN) open, short to ground, or short to voltage
- RCM
- instrument cluster
