Test C: Driver's Door Module Does Not Respond To Scan Tool
- Turn ignition switch to LOCK position. Disconnect 12-pin Driver's Door Module (DDM) harness connector C518. Inspect harness connector for loose, damaged or corroded terminals. If problem does not exist, go to next step. If problem exists, repair as necessary and retest system.
- Measure resistance of Light Blue/White wire between terminal No. 1 at DDM harness connector C518 and terminal No. 7 at DLC. See Figure
and Fig 1
. If resistance is more than 5 ohms, go to next step. If resistance is 5 ohms or less, replace DDM. See DRIVER'S DOOR MODULE
under REMOVAL & INSTALLATION.
- Disconnect 16-pin in-line harness connector C211. See Figure
. Inspect harness connector for loose, damaged or corroded terminals. If problem does not exist, go to next step. If problem exists, repair as necessary and retest system.
- Measure resistance of Light Blue/White wire between terminal No. 4 at male half of harness connector C211 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 harness connector C211 and DDM. If resistance is more than 5 ohms, repair open in Light Blue/White wire between harness connector C211 and DLC.
