Power Door Lock Test 22A - Inoperative Door Lock Inhibit Circuit

NOTE: Perform POWER DOOR LOCK TEST 1A  before proceeding with this test. For connector terminal identification, refer to CONNECTOR IDENTIFICATION  . For wiring diagrams, refer to WIRING DIAGRAMS  . Perform, after each repair, VERIFICATION TEST VER-1A - VERIFICATION PROCEDURE  .
CAUTION: Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.
  1. Open driver's door. Using scan tool, read driver's door ajar status. If scan tool displays DR DOOR AJAR: CLOSED, go to next step. If scan tool does not display DR DOOR AJAR: CLOSED, go to DOOR AJAR TEST 3A  .
  2. Ensure key is in ignition switch. Using scan tool, read key-in ignition status. If scan tool displays KEY-IN IGN: CLOSED, replace Body Control Module (BCM). BCM is located with junction block under driver's side instrument panel. See Figure . If scan tool does not display KEY-IN IGN: CLOSED, go to next step.
  3. Disconnect key-in ignition switch connector. See Figure in CHIME TEST 4B. Using scan tool in ohmmeter mode, measure resistance at terminal No. 2 (Black wire) on key-in ignition switch connector. If resistance is 5 ohms or greater, repair open Black wire. If resistance is less than 5 ohms, go to next step.
  4. Connect jumper wire between key-in ignition switch connector terminals. Using scan tool, read key-in ignition status. If scan tool displays KEY-IN IGN: CLOSED, replace ignition switch. If scan tool does not display KEY-IN IGN: CLOSED, go to next step.
  5. Access Body Control Module (BCM) connector "A". BCM is located with junction block under driver's side instrument panel. See Figure . Remove connector cover. Do not disconnect connector. Backprobe connector using a jumper wire. Connect jumper wire between ground and terminal No. 4 (Light Blue wire).
  6. Using scan tool, read key-in ignition status. If scan tool displays KEY-IN IGN: CLOSED, repair open Light Blue wire. If scan tool does not display KEY-IN IGN: CLOSED, go to next step.
  7. Turn ignition off. Disconnect BCM connector "A". Inspect connector terminals and repair as needed. If connector is okay, replace BCM.
