Test 92A - All Doors Fail To Unlock From Any Switch

NOTE: Perform TEST 87A  or 95A before proceeding with this test. For connector terminal ID, see CONNECTOR IDENTIFICATION  and WIRING DIAGRAMS  . Drive vehicle to update OTIS and perform TEST VER-1 - VERIFICATION PROCEDURE  after each repair.
CAUTION: Always turn ignition off prior to disconnecting any module connector.
  1. Remove door unlock relay from junction block. See Figure . Junction block is located behind end cover, on left side of instrument panel. Using scan tool, actuate door unlock relay. Go to next step.
  2. Using test light, probe terminal "C" (Pink/Violet wire) on door unlock relay socket. If test light does not flash, go to step 5). If test light flashes, go to next step.
  3. Stop actuation. Remove door lock relay. Using scan tool in ohmmeter mode, measure resistance at terminal "D" (Black wire) on door lock relay connector. If resistance is 5 ohms or greater, repair open Black wire. If resistance is less than 5 ohms, go to next step.
  4. Using an external ohmmeter, measure resistance between component terminals "A" (Orange/Black wire) and "D" (Black wire) on door lock relay. If resistance is 5 ohms or greater, replace door lock relay. If resistance is less than 5 ohms, replace door unlock relay.
  5. Gain access to Body Control Module (BCM). BCM is located behind right kick panel. Leave BCM connectors connected. Using test light, backprobe terminal No. 21 (Pink/Violet wire) on BCM Gray connector. Using scan tool, actuate door unlock relay. If test light flashes, repair open Pink/Violet wire. If test light does not flash, go to next step.
  6. Stop actuation. Turn ignition off. Disconnect BCM Gray connector. Disconnect Remote Keyless Entry (RKE) module. See Figure . Using scan tool in ohmmeter mode, measure resistance at terminal No. 21 (Pink/Violet wire) on BCM Gray connector. If resistance is less than 5 ohms, repair short to ground in Pink/Violet wire. If resistance is 5 ohms or greater, replace BCM.
