- 18. Press the engine start/stop button to select the OFF mode.
- 19. Remove the glove box (see GLOVE BOX REMOVAL/INSTALLATION ).
- 20. Disconnect the connector (A) from the remote slot control unit (B)
- 21. Inspect the connector and the socket terminals to be sure they are all making good contact.
- If the terminals are bent, loose or corroded, repair them as necessary, and recheck the system.
- If the terminals look OK, go to step 22.
- 22. With the connector still disconnected, do these input tests at the following connector.
- If any test indicates a problem, find and correct the cause, then recheck the system.
- If all the input tests prove OK, go to step 23.CONTROL UNIT INPUT TEST REFERENCE
Cavity Wire Test condition Test: Desired result Possible cause if desired result is not obtained 27 RED Disconnect the remote slot 16P connector and keyless access control unit connector B (32P) Check for continuity between terminal No. 27 and remote slot 16P connector terminal No. 14: There should be continuity. An open or high resistance in the wire Check for continuity between terminal No. 27 and keyless access control unit connector B (32P) terminal No. 27: There should be continuity. Check for continuity between terminal No. 27 and body ground: There should be no continuity. A short to ground in the wire
- 23. Reconnect the connector to the remote slot control unit, and do these input tests at the following connector.
- If any test indicates a problem, find and correct the cause, then recheck the system.
- If all the input tests prove OK, go to step 24.CONTROL UNIT INPUT TEST REFERENCE
