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

Circuit/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.
1. Ignition ON, headlamp switch OFF, verify the scan tool Headlamp Switch parameter is Inactive.
• If not Inactive, refer to Headlamps Malfunction (w/o TT6) (Headlamps Malfunction (w/o TT6))Headlamps Malfunction (w/TT6) (Headlamps Malfunction (w/TT6)).
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, doors closed, verify the scan tool Door Ajar Switch parameters are Inactive.
• If not Inactive, refer to Courtesy Lamps Malfunction (Courtesy Lamps Malfunction).
4. Ignition ON, rear gate closed, verify the scan tool Liftgate Ajar Switch parameter and the Liftglass Ajar Switch parameter are Closed.
• If not Closed, refer to Courtesy Lamps Malfunction (Courtesy Lamps Malfunction).
5. Ignition ON, radio ON, adjust the radio balance and fade to the left front speaker.
• If the speaker does not operate properly, refer to Speaker Malfunction (Speaker Malfunction).
6. Verify that the Key In Ignition Status parameter is Key In when the key is in the ignition and Key Out when the key is out of the ignition.
Circuit/System Testing
1. Ignition OFF, disconnect the X201 harness connector at the ignition switch.
2. Ignition ON, verify the scan tool Key In Ignition parameter is Key Out.
• If not the specified value, test the signal circuit terminal E6 for a short to ground. If the circuit tests normal, replace the BCM
3. Install a 3A fused jumper wire between the signal circuit terminal E6 and ground. Verify the scan tool Key In Ignition parameter is Key In.
• If not the specified value, test the signal circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the BCM.
4. 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 BCM replacement, setup, and programming
