Test 41G - Repairing Door Lock Problem

WARNING: This page is about a different car, the 1994 Chrysler LeBaron. 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 diagram, see WIRING DIAGRAMS  . Perform TEST VER-1 after each repair.
CAUTION: Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.
  1. Using DRB, stop door lock actuation. Ensure DRB is in voltmeter mode. Gain access to relay center, located under dash, attached to left kick panel. See Figure . Disconnect ADL relay. Measure voltage at ADL relay terminal "A" (Orange/White wire). With probe connected, actuate door locks and observe voltage. If voltage does not pulse between zero and 10 volts, repair open in Orange/White wire between ADL relay and Body Control Module (BCM) Black connector. If voltage pulses between zero and 10 volts, go to next step.
  2. Using DRB, stop door lock actuation. Using an external ohmmeter, check resistance between terminal "A" (Orange/White wire) and terminal "C" (Black wire) of ADL relay. If resistance is not 65-100 ohms, replace relay. If resistance is 65-100 ohms, go to next step.
  3. Using DRB in voltmeter mode, measure voltage at ADL relay terminal "D" (Red wire). If voltage is less than 10 volts, repair open in Red wire. If voltage is more than 10 volts, go to next step.
  4. Place DRB in ohmmeter mode. Measure resistance at ADL relay terminal "C" (Black wire). If resistance is more than 10 ohms, repair open to ground in Black wire. If resistance is less than 10 ohms, reconnect ADL relay. Go to next step.
  5. Gain access to right door lock switch. Measure resistance at ADL relay terminal "B" (Orange/Black wire). If resistance is less than 10 ohms, repair Orange/Black wire for short to ground. If resistance is more than 10 ohms, go to next step.
  6. Reinstall ADL relay. Put DRB in voltmeter mode. Measure voltage at right door lock switch terminal No. 4 (Pink/Black wire). Using DRB, actuate door locks. If voltage does not pulse from zero to 10 volts, replace ADL relay. If voltage pulses from zero to 10 volts, go to next step.
  7. Using DRB, stop door lock actuation. Ensure right door lock switch connector is connected. Measure voltage at right door lock switch terminal No. 1 (Orange/Violet wire). Using DRB, actuate door locks. If voltage does not pulse from zero to 10 volts, replace right door lock switch. If voltage pulses from zero to 10 volts, go to next step.
  8. Using DRB, stop door lock actuation. Gain access to left door lock switch. Disconnect left door lock switch connector. Measure voltage at left door lock switch connector terminal No. 2 (Pink/Violet wire). Using DRB, actuate door locks. If voltage does not pulse from zero to 10 volts, repair open Pink/Violet wire between left door lock switch and right door lock switch. If voltage pulses from zero to 10 volts, go to next step.
  9. Using DRB, stop door lock actuation. Put DRB in ohmmeter mode. Measure resistance at left door lock switch connector terminal No. 2 (Black wire). If resistance is less than 5 ohms, replace left door lock switch. If resistance is more than 5 ohms, open in Black wire between left door lock switch and ground.
