Test 96A - Left Front Door Fails To Lock & Unlock From Any Switch

NOTE: For connector terminal identification and wiring diagrams, see BODY CONTROL COMPUTER  section in this article. Perform TEST VER-1  VERIFICATION TEST after each repair.
CAUTION: Always turn ignition off prior to disconnecting any module connector.
  1. Remove key from ignition switch. Gain access to Remote Keyless Entry (RKE) module. See Figure . Disconnect RKE module Black connector. Go to next step.
  2. Using scan tool in ohmmeter mode, check resistance of RKE module Black connector terminal "H" (Black wire). If resistance is 5 ohms of greater, repair open Black wire. If resistance is less than 5 ohms, go to next step.
  3. Connect jumper wire between RKE module Black connector terminals "G" (Pink/Black wire) and "H" (Black wire). Depress left front door lock switch to LOCK position. If left front door lock operates, replace RKE module. If left front door lock does not operate, go to next step.
  4. Remove jumper cable. Using scan tool in voltmeter mode, check voltage on RKE module Black connector terminal "A" (Pink wire). If voltage is 10 volts or less, repair open Pink wire. If voltage is more than 10 volts, go to next step.
  5. Check voltage on RKE module Black connector terminal "C" (Orange/White wire). Depress and hold door lock switch to LOCK position. If voltage is 10 volts or less, repair open Orange/White wire. If voltage is more than 10 volts, go to next step.
  6. Release door lock switch. Check voltage on RKE module Black connector terminal "E" (Pink/Violet wire). Depress and hold door lock switch to UNLOCK position. If voltage is 10 volts or less, repair open Pink/Violet wire. If voltage is more than 10 volts, go to next step.
  7. Reconnect RKE module Black connector. Check voltage on RKE module Black connector terminal "G" (Pink/Black wire). Depress and hold door lock switch to UNLOCK position. If voltage is 10 volts or less, replace RKE module. If voltage is more than 10 volts, go to next step.
  8. Release lock switch. Remove left front door trim panel. Disconnect left front door lock motor connector. Using scan tool in voltmeter mode, check voltage on left front door lock motor connector terminal No. 1 (Orange/Black wire). Depress and hold door lock switch to LOCK position. If voltage is 10 volts or less, repair open Orange/Black wire. If voltage is more than 10 volts, go to next step.
  9. Release lock switch. Check voltage on door lock motor connector terminal No. 2 (Pink/Violet wire). Depress door lock switch to UNLOCK position. If voltage is 10 volts or less, repair open Pink/Violet wire. If voltage is more than 10 volts, replace door lock motor.
