Test 35B - Repairing Doors Fail To LCK & UNLCK From Any SW

WARNING: This page is about a different car, the 1994 Eagle Vision, 1994 Dodge Intrepid, 1994 Chrysler New Yorker, 1994 Chrysler LHS, and 1994 Chrysler Concorde. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: For connector terminal identification, see CONNECTOR IDENTIFICATION  . For wiring diagrams, see WIRING DIAGRAMS  . Perform TEST VER-1 after each repair.
CAUTION: Always turn ignition switch to OFF position prior to disconnecting any module connector.
  1. Using DRB, actuate door lock relay. If doors do not lock, go to TEST 35C. If doors lock, use DRB to read door lock switch voltage. If voltage is more than 0.2 volt, go to TEST 35G  . If voltage is less than 0.2 volt, go to next step.
  2. Using DRB, read door lock switch voltage while depressing a door lock switch to LOCK position. If voltage is more than 1.7 volts, replace Body Control Module (BCM). BCM is located behind right kick panel. If voltage is less than 1.7 volts, go to next step.
  3. Turn ignition switch to OFF position. Disconnect BCM Bone connector. Using DRB in voltmeter mode, check voltage on BCM Bone connector terminal No. 9 (Orange/White wire) while depressing any door lock switch. If voltage is more than 10 volts, replace BCM. If voltage is less than 10 volts, go to next step.
  4. Remove right front door trim panel. Disconnect door lock switch connector. Using DRB in voltmeter mode, check voltage on door lock switch connector terminal No. 4 (Pink wire). If voltage is less than 10 volts, repair open Pink wire. If voltage is more than 10 volts, go to next step.
  5. Using DRB in ohmmeter mode, check resistance of door lock switch connector terminal No. 1 (Orange/Violet wire). If resistance is less than 5 ohms, repair short to ground in Orange/Violet wire. If resistance is more than 5 ohms, go to next step.
  6. Connect jumper wire between door lock switch connector terminals No. 1 (Orange/Violet wire) and No. 4 (Pink wire). Using DRB in voltmeter mode, check voltage on door lock switch connector terminal No. 1 (Orange/Violet wire). If voltage is less than 10 volts, repair open Orange/Violet wire. If voltage is more than 10 volts, replace both front door switches.
