the BCM.

4. Ignition OFF, disconnect the X1 harness connector at the BCM.

5. Test for infinite resistance between the signal circuit terminal 3 and ground.

瀚慖f less than the specified value, test the signal circuit for a short to ground.

6. If all circuits test normal, test or replace the steering wheel control switch - left.

Component Testing

Steering Wheel Control Switch - Left

1. Disconnect the harness connector at the steering wheel controls switch - left.

2. Cruise control switch ON, measure the resistance between terminal 1 and terminal 3 while individually activating and holding each cruise

control function switch and compare the resistance reading to the values in the table below.

瀚慖f not within the specified resistance range, replace the steering wheel controls switch - left.

replace the K84 keyless entry control module.

瀚慖f the test lamp is always ON, test either control circuit for a short to voltage. If the circuits test normal, replace the K84 keyless entry

control module.

9. If all circuits test normal, test or replace the A23D door latch assembly - driver.

Passenger and Rear Door Release Command Inoperative

1. Ignition OFF, disconnect the X4 harness connector at the K84 keyless entry control module.

2. Test for infinite resistance between the control circuit terminal 14 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.

3. If all circuits test normal, replace the K84 keyless entry control module.

Passenger or Rear Door Latch Malfunction

1. Ignition OFF, disconnect the harness connector at the appropriate A23 door latch assembly.

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

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

瀚慖f the test lamp is always OFF, test either control circuit for a short to ground or an open/high resistance. If the circuits test normal,

replace the K84 keyless entry control module.

瀚慖f the test lamp is always ON, test either control circuit for a short to voltage. If the circuits test normal, replace the K84 keyless entry

control module.

4. If all circuits test normal, test or replace the A23 door latch assembly.
