Diagnostic Test

CHECK FOR AN INTERMITTENT CONDITION
1. Turn the ignition on and open one of the front doors.
  NOTE: A front door must remain open whenever checking or erasing Amplifier DTCs.
2. With the scan tool, record and erase the Amplifier DTCs.
3. Turn the radio on and set the volume to 25.
4. Adjust the speakers to the rear and center.
5. With the scan tool, read the active Amplifier DTCs.
  Does the scan tool display active: B147D-CHANNEL 6 AUDIO SPEAKER OUTPUT CIRCUIT SHORTED TOGETHER?
  
  Yes
  - Go to step 2
  No
  - Test complete, the condition or conditions that originally set this DTC are not present at this time. Using the SYSTEM WIRING DIAGRAMS as a guide, check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals and correct pin tension.
  - Perform the BODY VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure .

1. Turn the ignition off.
2. Disconnect the Right Rear Speaker.
3. Measure the resistance of the speaker between the two terminals.
  NOTE: The graphic shows the connector for reference only. Measure between the speaker terminals.
  
  Is the resistance of the speaker less than 1 Ohm?
  
  Yes
  - Replace the Right Rear Speaker in accordance with the Service Information.
  - Perform the BODY VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure .
  No
  - Go to step 3
CHECK THE (X206) RIGHT REAR SPEAKER (+) CIRCUIT, AND THE (X296) RIGHT REAR SPEAKER (-) CIRCUITS FOR A SHORT TOGETHER

1. Disconnect the Amplifier C2 harness connector.
2. Measure the resistance between the (X206) Right Rear Speaker (+) circuit, and the (X296) Right Rear Speaker (-) circuit.
  Is the resistance below 10K Ohms?
  
  Yes
  - Repair the (X206) Right Rear Speaker (+) circuit for a short to the (X296) Right Rear Speaker (-) circuit.
  - Perform the BODY VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure .
