Circuit/System Verification

1. Ignition OFF, with the doors closed and locked, approach the vehicle with the keyless entry transmitter and pull the exterior driver door

handle. The driver door should unlock and unlatch allowing the driver door to be pulled open.

瀚慖f the driver door will not unlock and open with a single pull of the exterior door handle, refer to Driver Door Latch Malfunction.

2. With the doors closed and locked, approach the vehicle with the keyless entry transmitter and pull the exterior passenger door handle or the

exterior left rear door handle or the exterior right rear door handle. The appropriate door should unlock and unlatch allowing the door to be

pulled open.

瀚慖f all the passenger, left rear and right rear doors will not unlock and open with a single pull of the exterior door handle, refer to

Passenger and Rear Door Release Command Inoperative.

瀚慖f a door will not unlock and open with a single pull of the door handle, refer to Passenger or Rear Door Latch Malfunction.

Circuit/System Testing

Driver Door Latch Malfunction

1. Ignition OFF, disconnect the X2 harness connector at the K84 keyless entry control module.

2. Test for less than 10 ohm between the ground circuit terminal 6 and ground.

瀚慖f greater than the specified range, test the ground circuit for an open/high resistance.

3. Ignition OFF, connect the X2 harness connector and disconnect the X4 harness connector at the K84 keyless entry control module.

4. Test for infinite resistance between the control circuit terminal 3 and ground.

瀚慖f less than the specified value, test the control circuit for a short to ground. If the circuit tests normal, replace the K9 BCM.

5. Ignition OFF, connect the X4 harness connector at the K84 keyless entry control module.

6. Disconnect the harness connector at the A23D door latch assembly - driver.

7. Connect a test lamp between the control circuit terminal 5 and control circuit terminal 10.

8. Pull and release the exterior driver door handle, the test lamp should briefly illuminate while the exterior door handle is being pulled.
