Control Unit Input Test (With Keyless Entry)






1. Slide the driver's seat forward.
2. Leave the harness connected and make the tests shown on the following page by probing the back of the connectors.
3. Inspect the connector terminals to be sure they are all making good contact.
^ If the terminals are bent, loose, or corroded, repair them as necessary, and recheck the system.
^ If the terminals look OK, make the following input tests at the connector.
- If any test indicates a problem, find and correct the cause, then recheck the system.
- If all the input tests prove OK, the control unit must be faulty; replace it.

CAUTION: To prevent damage to the actuator, connect power and ground only momentarily.











*: Disconnect the connector, and make these tests at the wire terminals.







3. Check actuator operation by connecting power and ground according to the table.






CAUTION: To prevent damage to the actuator, apply battery voltage only momentarily.

4. If the actuator fails to work properly, replace it.
5. Check for continuity between the terminals in each switch position according to the table.






Passenger's Door Lock Actuator Test
1. Remove the door panel (see section 20).
2. Disconnect the 2-P connector from the actuator.

Front Passenger's Door:






Rear Passenger's Door:

NOTE: The left rear actuator is shown; the right rear actuator is similar.






3. Check actuator operation by connecting power and ground according to the table.






CAUTION: To prevent damage to the actuator, apply battery voltage only momentarily.

4. If the actuator fails to work properly, replace it.

Tailgate Lock Actuator Test (Wagon)
1. Open the tailgate, and remove the tailgate trim panel.
2. Disconnect the 4-P connector from the actuator.
3. Test actuator operation by connecting power and ground to the C and D terminals.
Test the actuator in each direction by switching the leads.

CAUTION: To prevent damage to the motor, connect power and ground only momentarily.






4. If the actuator fails to operate properly replace it.

Remote Transmitter Replacement - (Wagon)
Use the following procedure when replacing one or both remote transmitters:
1. Open the driver's door.
2. Press and hold the driver's master door lock switch down in the UNLOCK position.
3. Quickly insert and remove the key from the ignition switch five times, then insert the key the sixth time, and leave it in the ignition switch. (This routine must be done within 1O seconds.) All the doors will lock and unlock to indicate that the control unit is in the program mode.
4. Press either button on the replacement transmitter. All the doors except the driver's door will lock and unlock to indicate that the control unit has accepted the transmitter into its memory. If either transmitter button is pressed again, all the doors will lock and unlock.
5. To program a second transmitter, press either button on that transmitter. The doors should lock and unlock as described in step 4.
6. Release the driver's master door lock switch.
7. To exit the program mode, close the driver's door or remove the key from the ignition switch.
