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.
Diagnostic Fault Information
sounds good, thaCircuit/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).

sounds good, thaCircuit/System Verification
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.
sounds good, tha 1. Ignition ON, headlamp switch OFF, verify the scan tool Headlamp Switch ON 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, 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 ON, radio ON, adjust the radio balance and fade to the left front speaker.
• If the speaker does not operate properly, refer to Radio Front Side Door Speaker Replacement (Radio Front Side Door Speaker Replacement) .
5. Verify that the Ign. Off/Run/Crank parameter is Active when the key is in the ignition and Inactive when the key is out of the ignition.
Circuit/System Testing
1. Ignition OFF, disconnect the harness connector at the ignition switch.
2. Ignition ON, verify that a test lamp illuminates between the B+ circuit terminal 2 and ground.
• If the test lamp does not illuminate, test the B+ circuit for an open/high resistance. If the circuit tests normal and the ignition circuit fuse is open, test the signal circuit terminal 4 for a short to ground.
3. Verify the scan tool Ign. Off/Run/Crank parameter is Inactive.
• If not the specified value, test the signal circuit terminal 4 for a short to voltage. If the circuit tests normal, replace the BCM.
4. Install a 3A fused jumper wire between the signal circuit terminal 4 and the B+ circuit terminal 2. Verify the scan tool Ign. Off/Run/Crank parameter is Active.
• If not the specified value, test the signal circuit for an open/high resistance. If the circuit tests normal, replace the BCM.
5. If all circuits test normal, test or replace the ignition switch.
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 the BCM replacement, setup, and programming
