Test D: Remote Entry System

CAUTION: Perform test ONLY if instructed to do so.
NOTE: This section contains a number of sub-sections for handling different types of problems found with the remote entry system reported by the customer. Find the specific problem in the list below, and go the step specified unless otherwise directed from a referencing test procedure. See TEST D SYMPTOM INDEX  table.
TEST D SYMPTOM INDEX

Symptom Perform Step No.
No Response Unless Transmitter Is Held Close To Vehicle  1
Problems Entering Or Exiting Transmitter Program Mode  2
Module No Longer Responds To A Transmitter Which Was Previously Programmed  11
Remote Functions Do Not Work In Extreme Weather  14
  1. If more than one transmitter is available, test the response of all the other transmitters that the customer brought in with the vehicle. If no other transmitters are available, go directly to step  3 . If all other transmitters operate, then replace the faulty transmitter. Program replacement transmitter. See REMOTE TRANSMITTER  under PROGRAMMING. Repeat quick test, see TEST A: QUICK TEST  . If none of the other transmitters work, then go to step  10 .
  2. Make sure that the shorting plug is not inserted into RKE test connector. See Figure . If shorting plug is not in test connector, go to next step. If shorting plug is in connector, remove it, then reperform quick test. See TEST A: QUICK TEST  .
  3. Disconnect remote entry module connector. Test for continuity between terminal No. 1 (White/Yellow wire) of test connector and ground. See Figure . See WIRING DIAGRAMS  . If continuity exists, repair the short to ground. Reperform quick test, see TEST A: QUICK TEST  . If continuity does not exist, go to next step.
  4. Disconnect remote entry module connector. Test for continuity between terminal No. 1 (White/Yellow wire) of test connector and battery. See Figure . See WIRING DIAGRAMS  . If continuity exists, repair the short to battery. Reperform quick test, see TEST A: QUICK TEST  . If continuity does not exist, go to next step.
  5. Test for continuity between terminal No. 2 (Gray/Yellow wire) of test connector and ground. See Figure . See WIRING DIAGRAMS  . If continuity exists, repair the short to ground. Reperform quick test, see TEST A: QUICK TEST  . If continuity does not exist, go to next step.
  6. Test for continuity between terminal No. 2 (Gray/Yellow wire) of test connector and battery. See Figure . See WIRING DIAGRAMS  . If continuity exists, repair the short to voltage. Reperform quick test, see TEST A: QUICK TEST  . If continuity does not exist, go to next step.
  7. Measure the voltage between terminal No. 9 (White/Yellow wire) remote entry module connector and ground. See Figure . See WIRING DIAGRAMS  . If measured voltage is between 4 and 6 volts, go to next step. If measured voltage is not within the specified range, replace the electronic remote entry module. See REMOTE ENTRY MODULE  under REMOVAL & INSTALLATION. Reperform quick test, see TEST A: QUICK TEST  .
  8. Measure the continuity between terminal No. 10 (Gray/Yellow wire) of remote entry module and ground. See Figure . See WIRING DIAGRAMS  . If continuity exists, go to next step. If continuity does not exist, replace the remote entry module. See REMOTE ENTRY MODULE  under REMOVAL & INSTALLATION. Reperform quick test, see TEST A: QUICK TEST  .
  9. Reconnect remote entry module connector. Measure the voltage between terminal White/Yellow wire of RKE test connector and ground. If measured voltage is between 4 and 6 volts, go to next step. If measured voltage is not within the specified range, repair open in White/Yellow wire between test connector and remote entry module connector. Reperform quick test, see TEST A: QUICK TEST  .
  10. Measure the continuity between Gray/Yellow wire of RKE test connector and ground. If continuity exists, go to next step. If continuity does not exist, repair open in Gray/Yellow wire between test connector and remote entry module connector. Reperform quick test, see TEST A: QUICK TEST  .
    11. NOTE: Perform this step only after performing step  1 .
  11. Turn the ignition switch to ON. Insert a shorting plug into RKE test connector. See Figure . If all doors lock then unlock, go to next step. If door locks do not respond, go to step  2 .
    12. NOTE: Transmitter buttons may have to be pushed more than once.
  12. Ensure the ignition switch is still in ON position. Press any button on the transmitter. Repeat this sequence for each of the owner's transmitters (up to four total). If all doors lock and then unlock, go to next step. If there is no response from the door locks (even after three button presses) then go to step  1 . If step  1 has already been performed, then replace transmitter batteries and reperform this step. If still no response, then replace electronic remote entry module. See REMOTE ENTRY MODULE  under REMOVAL & INSTALLATION. Reperform quick test, see TEST A: QUICK TEST  .
  13. Turn the ignition switch to OFF position. Ensure shorting plug is removed from RKE test connector. If all doors lock then unlock, repeat quick test. See TEST A: QUICK TEST  , begin at step 3)  . If there is no response from the door locks, then replace electronic remote entry module. See REMOTE ENTRY MODULE  under REMOVAL & INSTALLATION. Reperform quick test, see TEST A: QUICK TEST  .
  14. Bring vehicle to room temperature and perform the quick test. See TEST A: QUICK TEST  . If module passes quick test, then replace electronic remote entry module. See REMOTE ENTRY MODULE  under REMOVAL & INSTALLATION. Reperform quick test, see TEST A: QUICK TEST  . If the module fails a quick test step, then perform actions as directed by quick test. Repeat quick test when repairs are completed.
