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.
4. Turn the volume level to 25.
5. Adjust the speakers to the front and center.
6. With the scan tool, read the active Amplifier DTCs.
  Does the scan tool display active: B1464-CHANNEL 1 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.
