Test W: The Air Bag Warning Indicator Is Never On
PINPOINT TEST W: THE AIR BAG WARNING INDICATOR IS NEVER ONW1-W3:
W3-W5:
W6:
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, a diagnostic trouble code (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 voltage.
Possible Causes
- circuit 31S-JA14 (BK/GN) open, short to ground, or short to voltage
- RCM
- instrument cluster
