Test E: Power Door Locks Inoperative Using Remote Transmitter

NOTE: After making any repair, repeat Generic Electronic Module (GEM) self-test using WDS or NGS tester.
  1. Using driver's door lock switch, lock and unlock doors. If all doors lock and unlock, go to next step. If all doors do not lock and unlock, go to TEST B: SINGLE DOOR LOCK INOPERATIVE (EXCEPT DRIVER'S DOOR) .
  2. Turn ignition switch to LOCK position. Connect Worldwide Diagnostic System (WDS) tester or New Generation Star (NGS) tester to Data Link Connector (DLC), located below instrument panel. See Figure. Turn ignition switch to RUN position.Using WDS or NGS tester, access GEM FUNCTIONS TESTS, TRANSMITTER TIC/DATA menu. Also access PROGRAM TIC and select 4 memory locations. Record alpha-numeric codes. If 2 TICs are stored at TIC1, TIC2, TIC3 and TIC4 positions, go to next step. If no TICs are stored at TIC1, TIC2, TIC3 and TIC4 positions, program all remote keyless entry transmitters. See REMOTE TRANSMITTER  under PROGRAMMING.
  3. Using WDS or NGS tester, access GEM FUNCTION TESTS. While pressing and releasing keyless entry remote transmitter LOCK and UNLOCK buttons, monitor GEM LAST TIC/DATA RECEIVED. If an 8-digit alpha-numeric code is not displayed for LAST TIC RECEIVED and/or does not match button pressed, go to next step. If an 8-digit alpha-numeric code is displayed for LAST DATA RECEIVED, and LAST TIC/DATA RECEIVEDmatches buttons pressed, go to step  5.
  4. Using WDS or NGS tester, access GEM FUNCTION TESTS. While pressing keyless entry remote transmitter LOCK and UNLOCK buttons of second transmitter, monitor transmitter TIC/DATA. If an 8-digit alpha-numeric code is not displayed for LAST TIC RECEIVED and/or LAST DATA RECEIVED does not match button pressed, go to next step. If an 8-digit alpha-numeric code is displayed for LAST TIC RECEIVED, and LAST DATA RECEIVED matches button pressed, check remote transmitter battery condition. If battery condition is okay, replace remote transmitter and program all transmitters. See REMOTE TRANSMITTER  under PROGRAMMING. If battery is faulty, replace as necessary. After repair, test system for normal operation.
  5. Using WDS or NGS tester, access GEM FUNCTION TESTS. Monitor TRANSMITTER TIC/DATA using recorded alpha-numeric codes recorded in step 2)  . If TIC RECEIVED is one of the TICs recorded in step 2)  , go to next step. If TIC RECEIVED is not one of the TICs recorded in step 2)  , program remote transmitter(s). See REMOTE TRANSMITTER  under PROGRAMMING. After repair, test system for normal operation.
  6. Using WDS or NGS tester, access GEM FUNCTION TESTS, monitor TRANSMITTER TIC/DATA. If each button pressed on remote transmitter creates expected LAST DATA RECEIVED output, go to next step. If each button pressed on remote transmitter does not create expected LAST DATA RECEIVED output, program remote transmitter(s). See REMOTE TRANSMITTER  under PROGRAMMING. After repair, test system for normal operation.
  7. Disconnect all GEM harness connectors. Check all GEM harness connectors terminals for corroded or pushed-out pins. If connector or terminals are faulty, repair or replace as necessary. If connector and terminals are okay, reconnect all GEM harness connectors. Ensure all other system connectors are properly seated. Operate system and verify if concern is still present. If concern still present, install a new GEM. See GENERIC ELECTRONIC MODULE  under REMOVAL & INSTALLATION. If concern is not present, system is operating properly. Clear DTCs and check system for normal operation.
