Test H: One-Touch Down Feature Inoperative

NOTE: After all repairs, clear DTCs and recheck system operation. See WIRING DIAGRAMS  for circuit identification and repair.
  1. Using NGS tester, monitor GEM PID IGN_GEM while turning ignition switch through all positions. If PID IGN_GEM values agree with ignition switch positions, go to next step. If PID IGN_GEM values do not agree with ignition switch positions, check battery saver and accessory delay relays. See ACCESSORY DELAY RELAY  and BATTERY SAVER & ONE-TOUCH DOWN RELAYS  under COMPONENT TESTS. Check ignition switch. See STEERING COLUMN SWITCHES - EXPLORER & MOUNTAINEER article. Check ignition circuits. See POWER DISTRIBUTION article in WIRING DIAGRAMS.
  2. Using NGS tester, retrieve and record continuous DTCs. Clear continuous DTCs. Perform GEM self-test. If no DTCs, or DTCs B1398 or B1400, are retrieved, go to next step. If DTC B1342 is retrieved, replace GEM. See GENERIC ELECTRONIC MODULE  under REMOVAL & INSTALLATION.
  3. Turn ignition switch to RUN position. Using NGS tester, trigger GEM active command ACCY RLY on. Monitor GEM PID D_PWRLY while triggering active command ONE TOUCH on and off. If PID D_PWRLY value does not agree with command mode and displays OFFO-G, go to next step. If PID D_PWRLY value does not agree with command mode and displays ON-B-, go to step  7 . If PID D_PWRLY value agrees with command mode, go to step  9 .
  4. Turn ignition switch to LOCK position. Remove one-touch down relay from relay module, located behind center of instrument panel. Test one-touch down relay. See BATTERY SAVER & ONE-TOUCH DOWN RELAYS  under COMPONENT TESTS. If one-touch down relay is okay, go to next step. If one-touch down relay is faulty, replace one-touch down relay.
  5. Remove accessory delay relay from relay module. Measure resistance of Light Blue/Black wire between one-touch down relay socket terminal No. 2 and accessory delay relay socket terminal No. 30. See Figure and Figure . If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, repair open or high resistance in Light Blue/Black wire.
  6. Turn ignition switch to LOCK position. Disconnect GEM 18-pin harness connector C283. Measure resistance of Yellow/Red wire between one-touch down relay socket terminal No. 1 and GEM harness connector C283 terminal No. 7. See Figure and Figure . If resistance is less than 5 ohms, replace GEM. See GENERIC ELECTRONIC MODULE  under REMOVAL & INSTALLATION. If resistance is 5 ohms or more, repair open or high resistance in Yellow/Red wire.
  7. Turn ignition switch to LOCK position. Remove one-touch down relay from relay module, located behind center or instrument panel. Test one-touch down relay. See BATTERY SAVER & ONE-TOUCH DOWN RELAYS  under COMPONENT TESTS. If one-touch relay is okay, go to next step. If one-touch down relay is faulty, replace one-touch relay.
  8. Turn ignition switch to LOCK position. Disconnect GEM 18-pin harness connector C283. Turn ignition switch to RUN position. Measure voltage between ground and one-touch down relay socket terminal No. 1 (Yellow/Red wire). See Figure . If any voltage exists, repair short to voltage in Yellow/Red wire between one-touch down relay and GEM. If no voltage exists, replace GEM. See GENERIC ELECTRONIC MODULE  under REMOVAL & INSTALLATION.
  9. Turn ignition switch to LOCK position. Remove one-touch down relay from relay module, located behind center or instrument panel. Test one-touch down relay. See BATTERY SAVER & ONE-TOUCH DOWN RELAYS  under COMPONENT TESTS. If one-touch relay is okay, go to next step. If one-touch down relay is faulty, replace one-touch relay.
  10. Turn ignition switch to RUN position. Measure voltage between ground and one-touch down relay socket terminals No. 2 and 5 (both Light Blue/Black wires). See Figure . If more than 10 volts exist at both terminals, go to next step. If 10 volts or less exist at either terminal, repair open in appropriate Light Blue/Black wire(s).
  11. Turn ignition switch to LOCK position. Disconnect GEM 18-pin harness connector C283. Disconnect left front window motor 2-pin harness connector C504. Measure resistance between left front window motor harness connector Red wire terminal and GEM harness connector C283 terminal No. 10 (Gray wire). See Figure . If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, repair open or high resistance in Red wire or Gray wire.
  12. Measure resistance between left front window motor harness connector C504 Red wire terminal and GEM harness connector C283 terminal No. 2 (Orange/White wire). See Figure . If resistance is less than 5 ohms, replace GEM. See GENERIC ELECTRONIC MODULE  under REMOVAL & INSTALLATION. If resistance is 5 ohms or more, repair open or high resistance in Orange/White wire or Red wire.
