Circuit/System Testing

Chime Always On
1. Ignition ON, headlamp switch OFF, verify the scan tool Headlamp Off Switch parameter is Inactive.

• If not Inactive, Refer to Headlamps Malfunction (Headlamps Malfunction)

2. Ignition ON, park lamp switch OFF, verify the scan tool Park Lamp Switch parameter is Off.

• If not Off, Refer to Park Lamps Malfunction (Park Lamps Malfunction)

3. Ignition OFF, key out of the ignition, verify the scan tool Key In Ignition Status parameter is Inactive.

• If not Inactive, test the key in ignition switch signal circuit terminal 1 for a short to ground. If the circuit tests normal, replace the ignition switch.

4. Ignition ON, doors closed, verify the scan tool the LF and RF Door Ajar Switch parameters are Door Closed.

• If not Door Closed, go toCourtesy Lamps Malfunction (Courtesy Lamps Malfunction).

5. Ignition ON, doors closed, verify the scan tool Left and Right Rear Door Ajar Switch parameters are Closed.

• If not Closed, go toCourtesy Lamps Malfunction (Courtesy Lamps Malfunction).

6. If all circuits test normal, replace the BCM.

Chime Inoperative
1. Ignition OFF, key in the ignition, open the driver door. The courtesy lamps should illuminate.

• If the courtesy lamps do not illuminate, Refer to Courtesy Lamps Malfunction (Courtesy Lamps Malfunction).

2. Ignition ON, radio ON, adjust the radio balance and fade to the left front speaker.

• If the speaker does not operate properly, Refer to Speakers Inoperative - One or More (Speakers Inoperative - One or More).

3. If the speaker operates properly, replace the radio.

Repair Instructions

Perform the Diagnostic Repair Verification (Verification Tests) after completing the diagnostic procedure.

* Ignition and Start Switch Replacement (Service and Repair)
* Control Module References (Programming and Relearning) for BCM or radio replacement, setup, and programming
