Diagnostic Test

  1. 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. Using the scan tool, record and erase the Amplifier DTCs.
    3. Cycle the ignition switch from on to off, wait five seconds and then back to on.
    4. Turn the Radio on and set the volume to 25.
    5. Adjust the speakers to the rear and center.
    6. Using the scan tool, read the active Amplifier DTCs.

      Does the scan tool display active: B1477-CHANNEL 5 AUDIO SPEAKER OUTPUT CIRCUIT OPEN?

      Yes 

      • Go To  2

      No 

      • Test complete, the condition or conditions that originally set this DTC are not present at this time. Using the 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 STANDARD PROCEDURE - BODY VERIFICATION TEST .

    4. Turn the radio on and turn the volume to mid level.
    5. Adjust the speakers to the rear and center.
    6. With a voltmeter set to read in A/C voltage, measure the voltage of the Amplified Left Rear Speaker circuits in the Amplified Left Rear Speaker harness connector.

      Is the voltage present greater than 1 volt?

      Yes 

      No 

      • Go To  3
