Test D: Luggage Compartment Lid Inoperative Using Release Switch

NOTE: Factory code is printed on owner's wallet card, located in glove compartment and on Generic Electronic Module (GEM).
  1. If vehicle is equipped with remote keyless entry, go to next step. If vehicle is not equipped with remote keyless entry, go to step  20 .
  2. Connect New Generation Star (NGS) tester following manufacturers instructions. Retrieve GEM DTCs. If DTC B1554 exists, go to step  7 . If DTC B1551 or B553 exists, go to step  10 . If no DTCs exist, check operation of vehicle factory code. If factory code allows operation, system is okay at this time. Inform customer of factory code. If entering factory code does not remove fault, go to next step.
  3. Close luggage compartment lid (if open). Using NGS tester, access GEM active REAR DOOR LOCK CONTROL. Trigger luggage compartment UNLOCK to ON. If luggage compartment unlocks, go to next step. If luggage compartment does not unlock, go to step  10 .
  4. Disconnect luggage compartment release switch connector. Measure voltage between ground and luggage compartment release switch connector terminal No. 2 (Violet/Yellow wire). If voltage exists, go to next step. If no voltage exists, go to step  6 .
  5. Ensure ignition is off. Disconnect GEM 36-pin connector C201c. Measure voltage between ground and luggage compartment release switch connector terminal No. 2 (Violet/Red wire). See Figure . If voltage exists, repair short to power in Violet/Yellow wire between Central Junction Box (CJB) and luggage compartment lid release switch. If no voltage exists, go to step  19 .
  6. Measure resistance between ground and compartment luggage compartment release switch connector terminal No. 1 (Gray/Red wire). If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or greater, repair open in Gray/Red wire between luggage compartment lid release switch and luggage compartment lid release solenoid. Recheck system operation.
  7. Connect a fused jumper wire between luggage compartment lid release connector terminals. If luggage compartment lid unlocks, replace luggage compartment release switch. Recheck system operation. If luggage compartment lid does not unlock, go to next step.
  8. Disconnect GEM 26-pin connector C201c. Measure resistance between ground and luggage compartment release switch connector terminal No. 2 (Violet/Yellow wire). If resistance is greater than 10 k/ohms, go to next step. If resistance is 10 k/ohms or less, repair short to ground in Violet/Yellow wire between luggage compartment lid release switch and luggage compartment lid release solenoid. Recheck system operation.
  9. Measure resistance between luggage compartment release switch connector terminal No. 2 (Violet/Yellow wire) and GEM connector C201c terminal No. 3 (Pink/Orange wire). If resistance is less than 5 ohms, go to step  19 . If resistance is 5 ohms or greater, repair open in Pink/Orange or Violet/Yellow wire between GEM and luggage compartment lid release switch. Recheck system operation.
  10. Remove luggage compartment or liftgate (wagon) release relay. Test relay. See RELAYS  under COMPONENT TESTS. If relay is okay, go to next step. If relay is not okay, replace relay. Recheck system operation.
  11. Turn ignition switch to RUN position. Measure voltage between ground and luggage compartment release relay connector terminal No. 30 and 86. On wagon, measure voltage between liftgate unlock relay connector terminal No. 86 and 87. If more than 10 volts exists, go to step  13 . If 10 volts or less exists, go to next step.
  12. Turn ignition switch to LOCK position. Disconnect Central Junction Box (CJB) 36-pin connector C270c. On sedan, measure resistance in Pink/Orange wire between CJB connector terminal No. 33 and luggage compartment relay connector terminals No. 30 and 86. On wagon, measure resistance in Pink/Orange wire between CJB connector terminal No. 33 and luggage compartment relay connector terminals No. 86 and 87. If resistances are less than 5 ohms, repair open in CJB as necessary. Recheck system operation. If resistance is 5 ohms or greater, repair appropriate wire between CJB and luggage compartment relay or liftgate relay.
  13. On sedan, measure voltage between ground and luggage compartment release relay connector terminal No. 85. On wagon, measure voltage between ground and liftgate release relay connector terminal No. 85. If any voltage exists, go to next step. If no voltage exists, go to step  15 .
  14. Turn ignition switch to LOCK position. Disconnect GEM 26-pin connector C201c. Turn ignition switch to RUN position. On all models, measure voltage between ground and luggage compartment or liftgate relay connector terminal No. 85. If any voltage exists, repair short to power in Yellow/Light Green wire between luggage compartment lid or liftgate unlock relay and GEM. Recheck system operation. If no voltage exists, go to step  19 .
  15. Turn ignition switch to LOCK position. Measure resistance between ground and luggage compartment release or liftgate release relay connector terminal No. 85. If resistance is greater than 10 k/ohms, go to next step. If resistance is 10 k/ohms or less, repair short to ground in Yellow/Light Green wire between luggage compartment lid or liftgate unlock relay and GEM. Recheck system operation.
  16. Measure resistance in Yellow/Light Green between luggage compartment or liftgate release relay connector terminal No 85 and GEM connector C201c terminal No. 26. If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or greater, repair open in Yellow/Light Green wire. Recheck system operation.
  17. Disconnect luggage compartment or liftgate release solenoid connector. On sedan, measure resistance in Orange/Light Green wire between luggage compartment release relay connector terminal No. 87 and luggage compartment release solenoid connector terminal No. 2. On wagon, measure resistance in Dark Blue/Yellow wire between liftgate unlock relay and liftgate lock actuator connector terminal No. 2. If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or greater, repair open in Orange/Light Green or Dark Blue/Yellow wire. Recheck system operation.
  18. On sedan, measure resistance between ground and luggage compartment release solenoid connector terminal No. 3 (Black wire). On wagon, measure resistance between ground and liftgate lock actuator connector terminal No. 1 (Pink/Black wire). If resistance is less than 5 ohms, replace luggage compartment release solenoid or liftgate lock actuator. Recheck system operation. If resistance is 5 ohms or greater, repair open in Black or Pink/Black wire between luggage compartment lid release solenoid or liftgate lock actuator and ground. Recheck system operation.
  19. Disconnect all GEM connectors. Check for corroded, damaged or pushed out pins. Repair as necessary. Reconnect GEM connectors. Ensure connectors seat correctly. Recheck system operation. If fault still exists, replace GEM. Recheck system operation. If fault no longer exists, fault may have been caused by a loose or corroded connector.
  20. Disconnect luggage compartment release solenoid connector. Press luggage compartment release switch. Measure voltage between ground and luggage compartment release solenoid connector terminal No. 2 (Gray/Red wire). If more than 10 volts exist, go to next step. If 10 volts or less exists, go to step  22 .
  21. Measure resistance between ground and luggage compartment release solenoid connector terminal No. 3 (Black wire). If resistance is less than 5 ohms, replace luggage compartment release solenoid. Recheck system operation. If resistance is 5 ohms or more, repair open in Black wire. Recheck system operation.
  22. Disconnect luggage compartment release switch connector. Measure voltage between ground and luggage compartment release switch connector terminal No. 2 (Violet/Yellow wire). If 10 volts or more exist, go to next step. If 10 volts or less exists, repair open in Violet/Yellow wire between CJB and luggage compartment release switch. Recheck system operation.
  23. Measure resistance between ground and luggage compartment release switch connector terminal No. 1 (Gray/Red wire). If resistance is greater than 10 k/ohms, go to next step. If resistance is 10 k/ohms or less, repair short to ground in Gray/Red wire between CJB and luggage compartment release switch. Recheck system operation.
  24. Measure resistance in Gray/Red wire between luggage compartment release switch connector terminal No. 1 and luggage compartment lid release solenoid. If resistance is less than 5 ohms, replace luggage compartment release switch. Recheck system operation. If resistance is 5 ohms or greater, repair open in Gray/Red wire. Recheck system operation.
