Test C: Restraint Control Module Does Not Respond To Scan Tool
- Turn ignition switch to LOCK position. Disable air bag system. See appropriate AIR BAG RESTRAINT SYSTEMS article. Disconnect 26-pin Restraint Control Module (RCM) harness connector C276. RCM is located behind left center of instrument panel. See Figure
. Inspect connector for loose, damaged or corroded terminals. If connector is damaged, repair as necessary. If connector is not damaged, go to next step.
- Measure resistance in Light Blue/White wire between RCM harness connector C276 terminal No. 5 and DLC terminal No. 7. See Figure
and Fig 1
. If resistance is 5 ohms or less, replace RCM. See appropriate AIR BAG RESTRAINT SYSTEMS article. If resistance is more than 5 ohms, repair open in Light Blue/White wire between RCM and DLC. See DATA LINK CONNECTORS article in WIRING DIAGRAMS.
