Test B: Generic Electronic Module Does Not Respond To Scan Tool
- Turn ignition switch to LOCK position. Disconnect 26-pin Generic Electronic Module (GEM) harness connector C352. GEM is located behind instrument panel, next to central junction box. 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 GEM harness connector C352 terminal No. 6 and DLC terminal No. 7. See Figure
and Fig 1
. If resistance is 5 ohms or less, replace GEM. See REMOVAL & INSTALLATION
. If resistance is more than 5 ohms, repair open in Light Blue/White wire between GEM and DLC. See DATA LINK CONNECTORS article in WIRING DIAGRAMS.
