Pinpoint Test D - Remote Entry System Diagnosis

  1. Ensure antenna is installed properly. Disconnect antenna from door lock control module antenna plug. Inspect antenna connector for damage. Reconnect antenna to door lock control module. Repair or replace antenna as necessary. If antenna is okay, go to next step.
  2. If more than one transmitter is available, test response of each transmitter to vehicle. If other transmitters work okay, replace defective transmitter. If other transmitters do not work properly, go to next step.
  3. Ensure shorting plug has not been inserted into program connector behind left side of instrument panel. Remove shorting plug if present. Go to next step.
  4. Disconnect connector C1. Check for continuity between both pins of program connector. If continuity exists, replace program connector. If no continuity exists, go to next step.
  5. Disconnect control module C1. Check for continuity between ground and White/Yellow wire of program connector. If continuity exists, repair short-to-ground in White/Yellow wire. If no continuity exists, go to next step.
  6. Using test light, check for continuity between ground and White/Yellow wire of program connector. If test light glows, repair short-to-power in White/Yellow wire. If test light does not glow, go to next step.
  7. Check for continuity between ground and Gray/Yellow wire of program connector. If continuity exists, repair short-to-ground in Gray/Yellow wire. If no continuity exists, go to next step.
  8. Using test light, check for continuity between ground and Gray/Yellow wire of program connector. If test light glows, repair short-to-power in Gray/Yellow wire. If test light does not glow, go to next step.
  9. Measure voltage between connector C1, pin No. 15 and ground. If reading is between 4 and 6 volts, go to next step. If reading is less than 4, or more than 6 volts, replace door lock control module.
  10. Check for continuity between ground and connector C1, pin No. 10. If continuity exists, go to next step. If no continuity exists, replace door lock control module.
  11. Reconnect connector C2. Measure voltage between ground and White/Yellow wire of program connector. If reading is between 4 and 6 volts, go to next step. If reading is less than 4 volts, or more than 6 volts, repair open in White/Yellow wire.
  12. Check for continuity between ground and Gray/Yellow wire of program connector. If continuity exists, go to next step. If no continuity exists, repair open in Gray/Yellow wire.
  13. Turn ignition on. Insert shorting plug into program connector. If doors lock and unlock, go to next step. If doors do not lock and unlock, go to step 15).
  14. Press any button on transmitter. Repeat procedure for each transmitter. If, when using each transmitter, all doors lock then unlock, go to next step. If door locks do not respond after pressing button 3 times, go to step 1). If step 1) has been tried, replace transmitter batteries. If door locks still do not respond, replace door lock control module.
  15. Turn ignition off. Remove shorting plug from program connector. If doors lock and unlock, repeat PINPOINT TEST A  , steps 3) through 13). If doors do not lock and unlock, replace door lock control module.
  16. If door locks do not work in freezing temperature, bring vehicle to room temperature and perform PINPOINT TEST A  . If system passes Quick Test, replace door lock control module. If system does not pass Quick Test, service keyless entry system as necessary.
