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.

Circuit/System Description

The radio generates the audible warnings. The instrument cluster, the body control module (BCM), the inflatable restraint sensing and diagnostic module (SDM) or the object alarm module request audible warnings via Low Speed CAN-Bus signals.

Circuit/System Verification

Note: Before performing this diagnostics, make sure no indicators are illuminated after the instrument cluster performs a lamp test. If any indicators are illuminated after the bulb test, perform the indicator diagnostics before this diagnostics.

1. Ignition ON, radio ON, adjust the radio balance and fade to each speaker.

If any speaker does not operate properly, refer to Speaker Malfunction (Speaker Malfunction).

2. Ignition ON, buckle up driver seat belt, verify the scan tool Driver Seat Belt Status parameter is Buckled.

If not Buckled refer to Seat Belt Indicator Circuit Malfunction - Driver (Seat Belt Indicator Circuit Malfunction - Driver).

3. Ignition ON, headlamp switch OFF, verify the scan tool Headlamp On Switch parameter is Inactive.

If not Inactive, refer to Headlamps Malfunction (Headlamps Malfunction).

4. Ignition ON, parking lamp switch OFF, verify the scan tool Parklamp Switch parameter is Inactive.

If not Inactive, refer to Park, License, and/or Tail Lamps Malfunction (Park, License, and/or Tail Lamps Malfunction).

5. Ignition ON, turn signal switch OFF, verify the scan tool Left Turn Signal Switch parameter and the scan tool Right Turn Signal Switch parameter is Inactive.

If not Inactive, refer to Turn Signal Lamps and/or Indicators Malfunction (Turn Signal Lamps and/or Indicators Malfunction).

6. Ignition ON, doors closed, verify that all scan tool parameters listed below are Inactive.

* Driver Door Ajar Switch
* Passenger Door Ajar Switch
* Left Rear Door Ajar Switch
* Right Rear Door Ajar Switch

If any are not Inactive, refer to Door Ajar Indicator Malfunction (Door Ajar Indicator Malfunction).

7. Verify the scan tool Key in Ignition Status parameter is Inactive when the key is in the ignition and Active when the key is out of the ignition.

If the scan tool parameter does not operate properly, refer to Circuit/System Testing.

8. Ignition ON, verify that the scan tool Park Assist Switch parameter is Active when the parking assist is active and Inactive when the parking assist is Inactive.

If the scan tool parameter does not operate properly, refer to Parking Assist System Malfunction (Parking Assist System Malfunction).

9. If all tests operate properly, replace the A11 radio.

Circuit/System Testing

1. Ignition OFF, fully insert and remove the key in the ignition lock cylinder several times. Verify the scan tool Key In Cylinder Switch parameter changes from Active to Inactive.

If the parameter is always Inactive, test the S39 ignition switch signal circuit terminal 4 and the B+ circuit terminal 2 for an open/high resistance or a short to ground. If all circuits test normal, replace the S39 ignition switch.
If the parameter is always Active, test the S39 ignition switch signal circuit terminal 4 for a short to voltage. If all circuits test normal, replace the S39 ignition switch.

2. If all circuits test normal, replace the K9 BCM.

Repair Instructions

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