Test A: The Air Bag Warning Indicator Is Illuminated Continuously
PINPOINT TEST A: THE AIR BAG WARNING INDICATOR IS ILLUMINATED CONTINUOUSLYNormal Operation
During normal operation, the instrument cluster (IC) module will illuminate the air bag indicator continuously for 6 seconds after the ignition switch is placed to the RUN or ON position and then turn off. If the supplemental restraint system (SRS) is fault free, the air bag warning indicator will remain off. The restraints control module (RCM) will communicate to the IC module via the high-speed controller area network (HS-CAN). The IC module will illuminate the air bag indicator based on messaging from the RCM or if there is no communication between the RCM and IC module.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Instrument cluster (IC) module
- RCM
