Turn ignition switch to LOCK position. Disconnect GEM module harness connector C352. Inspect connector for loose, damaged or corroded terminals. Repair as necessary. If connector is okay, measure resistance in Light Blue/White wire between terminal No. 6 at GEM module harness connector C352 and terminal No. 7 at DLC. See Figure and Fig 1 . If resistance is 5 ohms or less, replace GEM. If resistance is greater than 5 ohms, repair open in Light Blue/White wire between GEM and DLC.
