Test H: Air Bag Diagnostic Monitor Does Not Respond
- Deactivate air bag system. See AIR BAG RESTRAINT SYSTEM article. Disconnect air bag diagnostic monitor 12-pin connector C277 (located behind right side of instrument panel cowl trim panel). Measure resistance between 12-pin air bag diagnostic monitor connector terminal No. 12 (Light Blue/White wire) and DLC terminal No. 7. See Figure. If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, repair open in Light Blue/White wire. Reconnect connectors. Repeat DATA LINK DIAGNOSTICS under COMMUNICATION NETWORK DIAGNOSTICS.
- Inspect air bag diagnostic monitor 12-pin connector C277 terminal No. 12 (Light Blue/White wire) and wire connection. If terminal and wire connection are okay, go to next step. If terminal and/or wire connection are damaged, repair as necessary. Reconnect connectors. Repeat DATA LINK DIAGNOSTICS under COMMUNICATION NETWORK DIAGNOSTICS.
- Inspect air bag diagnostic monitor terminals. If terminals are okay, replace air bag diagnostic monitor. If terminal(s) are damaged, repair as necessary. Reconnect connectors. Repeat DATA LINK DIAGNOSTICS under COMMUNICATION NETWORK DIAGNOSTICS .
