Diagnostic Instructions
* Perform the Diagnostic System Check - Vehicle (Initial Inspection and Diagnostic Overview) prior to using this diagnostic procedure.
* Review Strategy Based Diagnosis (Initial Inspection and Diagnostic Overview) for an overview of the diagnostic approach.
* Diagnostic Procedure Instructions (Initial Inspection and Diagnostic Overview)provides an overview of each diagnostic category.
Circuit/System Description
The radio generates the audible warning through the left speaker. The radio receives audible warning requests via the serial data circuit from the instrument panel cluster (IPC) or the body control module (BCM).

Circuit/System Testing
Important: Before performing this diagnostics, make sure no indicator(s) are illuminated after the IPC performs the displays test. If any indicators are illuminated after the bulb test, perform the indicator diagnostics before this diagnostic.
Chime Always On
1. Ignition ON, headlamp switch OFF, verify the scan tool Headlamp 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 Inactive.
• If not Inactive, refer to Park, License, and/or Tail Lamps Malfunction (Park, License, and/or Tail Lamps Malfunction).
3. Ignition ON, close all doors, verify the scan tool Door Ajar Switch parameters are Door Closed.
• If not Door Closed, refer to Courtesy Lamps Malfunction (Courtesy Lamps Malfunction).
4. Ignition OFF, key out of the ignition, verify the scan tool Key In Ignition Status parameter is Key Out.
• If not Key Out, test the key-in-ignition switch signal circuit terminal 1 for an open or short to voltage. If the circuit tests normal, replace the ignition switch.
5. If all circuits test normal, replace the BCM.
Chime Inoperative
1. Ignition OFF, with 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)
* Turn Signal Multifunction Switch Replacement (Turn Signal Multifunction Switch Replacement)
* Control Module References (Programming and Relearning)for the BCM or radio replacement, setup, and programming
