Test D: Delayed Accessory Feature Does Not Turn Off
- Check Door Ajar Switches - Using NGS tester, access DDM PIDs D_DR_DD and P_DR_DD. Open and close doors several times. If DDM PIDs D_DR_DD and P_DR_DD values agree, go to next step. If DDM PIDs D_DR_DD and P_DR_DD do not agree, go to step 9).
- Check Delayed Accessory Relay - Check delayed accessory relay. See DELAYED ACCESSORY RELAY/POWER WINDOW RELAY under COMPONENT TESTING. If relay is okay, go to next step. If relay is not okay, replace relay and retest system operation.
- Check Lighting Control Module (LCM) Timer - Using an ohmmeter, check resistance between ground and delayed accessory relay connector terminal No. 86 (Pink wire). See Figure . Wait 10 minutes. If resistance is more than 10 k/ohms after 10 minutes, go to next step. If resistance is 10 k/ohms or less after 10 minutes, go to step 6).
- Check Door Ajar Signal To Lighting Control Module (LCM) - Using an ohmmeter, check resistance between ground and delayed accessory relay connector terminal No. 86 (Pink wire). See Figure . Open driver door. If resistance is more than 10 k/ohms after opening driver door, go to next step. If resistance is 10 k/ohms or less after opening driver door, go to step 8).
- Check Yellow/Light Green Wire For Short To Power - Disconnect DDM 4-pin connector C522 (located in upper front corner of driver's door). Using a voltmeter, check voltage between ground and DDM 4-pin connector C522 terminal No. 3 (Yellow/Light Green wire). If voltage is more than 10 volts, repair short to power in Yellow/Light Green wire and retest system operation. If voltage is 10 volts or less, replace driver door module and retest system operation.
- Check Lighting Control Module (LCM) DTCs - Using NGS tester, perform LCM self-test. Retrieve and record LCM continuous DTCs. If no LCM DTCs are retrieved, go to next step. If any LCM DTCs are retrieved, go to AUTOLAMP SYSTEMS article to continue diagnosis.
- Check Pink Wire For Short To Ground - Remove delayed accessory relay from instrument panel fuse box. Using an ohmmeter, check resistance between ground and delayed accessory relay connector terminal No. 86 (Pink wire). See Figure . Disconnect Lighting Control Module (LCM) 12-pin connector C220 (located behind center of instrument panel). If resistance is more than 10 k/ohms after LCM is disconnected, go to next step. If resistance is 10 k/ohms or less after LCM is disconnected, repair short to ground in Pink wire and retest system operation.
- Check LCM PID IGN_LCM - Reconnect LCM 12-pin connector C220 and delayed accessory relay. Using NGS tester, access LCM PID IGN_LCM. If LCM PID IGN_LCM indicates OFF, replace driver door module and retest system operation. If LCM PID IGN_LCM does not indicate OFF, replace lighting control module and retest system operation.
- Check Driver Door Module (DDM) DTCs - Use results from DDM self-test performed in preliminary procedure. If no DDM DTCs were retrieved, go to next step. If any DDM DTCs are retrieved, go to POWER DOOR LOCKS & TRUNK RELEASE article to continue diagnosis.
- Check Driver & Passenger Door Ajar Switches - Remove passenger and driver door ajar switches (located in top rear of door, near latch assembly). Using an ohmmeter, check resistance between door ajar switch terminals while opening and closing switch. If resistance is more than 10 k/ohms with switch closed and less than 5 ohms with switch open, go to next step. If resistance is 10 k/ohms or less with switch closed and 5 ohms or more with switch open, replace appropriate door ajar switch and retest system operation.
- Check Dark Blue Wire For Open - Turn ignition off. Disconnect driver door ajar switch Gray connector C500. Disconnect DDM 16-pin connector C521 (located in upper front corner of driver's door). Using an ohmmeter, check resistance in Dark Blue wire between DDM 16-pin connector C521 terminal No. 5 and door ajar switch Gray connector C500. See Figure . If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, repair open in Dark Blue wire and retest system operation.
- Check Dark Blue Wire For Short To Power - Using a voltmeter, check voltage between ground and DDM 16-pin connector C521 terminal No. 5 (Dark Blue wire). If voltage is 10 volts or less, go to next step. If voltage is more than 10 volts, repair short to power in Dark Blue wire and retest system operation.
- Check Black/Orange Wire For Open - Turn ignition off. Disconnect passenger door ajar switches (located in top rear of door, near latch assembly). Disconnect DDM 16-pin connector C521 (located in upper front corner of driver's door). Using an ohmmeter, check resistance in Black/Orange wire between DDM 16-pin connector C521 terminal No. 6 and each passenger door ajar switch Gray connector. See Figure . If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, repair open in Black/Orange wire and retest system operation.
- Check Black/Orange Wire For Short To Power - Using a voltmeter, check voltage between ground and DDM 16-pin connector C521 terminal No. 6 (Black/Orange wire). If voltage is 10 volts or less, go to next step. If voltage is more than 10 volts, repair short to power in Black/Orange wire and retest system operation.
- Check Door Ajar Switch Ground Circuits For Open - Using an ohmmeter, check resistance between ground and door ajar switch connector Black wire terminal. If resistances are less than 5 ohms, replace driver door module and retest system operation. If any resistance is 5 ohms or more, repair open in appropriate Black wire and retest system operation.
