PINPOINT TEST A: THE AIR BAG WARNING INDICATOR IS ILLUMINATED CONTINUOUSLY - RCM DISCONNECTED OR INOPERATIVE, LOSS OF BATTERY FEED OR LOSS OF SIGNAL 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 supplemental restraint system (SRS) 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.
The RCM will communicate DTCs to the scan tool through the data link connector (DLC). If the scan tool displays NO COMMUNICATION when retrieving DTCs, refer to Information Bus (Module Communications Network) to diagnose the no communication concern.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Instrument cluster module
- RCM disconnected
- RCM
