Test D: Restraint Control Module (RCM) Does Not Respond To NGS Tester
NOTE:
After making any repair, perform data link diagnostic test. See DATA LINK DIAGNOSTIC TEST
under SELF-DIAGNOSTIC SYSTEM.
NOTE:
Restraint Control Module (RCM) may also be referred to as electronic crash sensor module.
- Turn ignition switch to LOCK position. Disable air bag system. See appropriate AIR BAG RESTRAINT SYSTEMS article. Disconnect Restraint Control Module (RCM) harness connector C310a. RCM is located behind center of instrument panel, on tunnel. Inspect connector for loose, damaged or corroded terminals. Repair connector as necessary. Measure resistance in Light Blue/White wire between terminal No. 4 at RCM harness connector C310a and terminal No. 7 at Data Link Connector (DLC). See Figure and Fig 1 . If resistance is 5 ohms or less, replace RCM. If resistance is greater than 5 ohms, go to next step.
- Disconnect in-line harness connector C263. In-line harness connector C263 is located behind right side of instrument cluster. Inspect connector for loose, damaged or corroded terminals. Repair connector as necessary. Measure resistance in Light Blue/White wire between terminal No. 2 at female half of in-line harness connector C263 and terminal No. 7 at DLC. See Figure and Fig 2 . If resistance is 5 ohms or less, repair open in Light Blue/White wire between male half of in-line harness connector C263 and RCM. If resistance is greater than 5 ohms, repair open in Light Blue/White wire between female half of in-line harness connector C263 and DLC.
