Test F: Illuminated Entry Does Not Operate With Transmitter

  1. Turn ignition off. Connect NGS tester following manufacturer's instructions. Select PID IGN_GEM. Turn ignition switch through all positions. If PID values agree with switch positions, go to next step. If PID values do not agree with switch positions, repair appropriate ignition switch circuit. Clear DTCs. Retest system.
  2. Retrieve continuous DTCs. Clear DTCs. Perform GEM on-demand self test. If no DTCs are retrieved, go to next step. If DTC B1342 is retrieved, replace GEM. Clear DTCs. Retest system. If DTC B1610 is retrieved, go to step 5).
  3. Press UNLOCK button on remote transmitter to unlock all doors and turn interior lights on. Press LOCK button on remote transmitter within 20 seconds of pressing UNLOCK button to lock doors and turn interior lights off. If illuminated entry does not work as specified, go to next step. If illuminated entry works as specified, system is operating properly at this time. If doors do not lock or unlock, go to TEST B  .
  4. Turn ignition off. Connect NGS tester following manufacturer's instructions. Turn ignition on. Monitor GEM PID ILLE_SW while turning RAP INT LAMP ON active command ON and OFF. If display does not read ON when commanded ON and OFF when commanded OFF, go to next step. If display reads ON when commanded ON and OFF when commanded OFF, replace GEM. Clear DTCs. Retest system.
  5. Using NGS tester, turn illuminated entry ON. Measure voltage by backprobing RAP module 22-pin connector terminal No. 10 (Brown/Light Green wire). See Figure . If voltage is 1.5 volts or less, go to next step. If voltage is greater than 1.5 volts, replace RAP module, then retest system.
  6. Using NGS tester, measure illuminated entry pulse widths while pressing LOCK and UNLOCK buttons on remote transmitter while observing NGS tester. If pulse widths are between 190 and 210 milliseconds for UNLOCK button and 290-310 milliseconds for LOCK button, go to next step. If pulse widths are not as specified, replace RAP module, then retest system.
  7. Turn ignition off. Disconnect 16-pin GEM connector C240. Measure resistance between 16-pin GEM connector C240 terminal No. 9 (Brown/Light Green wire) and RAP module 22-pin connector C257 terminal No. 10. See Figure . If resistance is less than 5 ohms, replace GEM. Clear DTCs and retest system. If resistance is more than 5 ohms, repair open in Brown/Light Green wire, then retest system.
