Bulletin Number: 15-240-19R; Revised: 05/08/19 Page 1 of 3 SERVICE PROCEDURE / INFORMATION: The causes of Symptoms 1, 2, 4, 5 and 6 are software concerns where in some cases, the amplifier status is not judged properly by the head unit. As a result, volume output is either muted (no output) or at the maximum. The cause of Symptom 3 is a hardware concern within the amplifier circuitry which also requires the unit be replaced with an exchange unit. Follow the procedure below to confirm this condition BEFORE ordering an exchange amplifier. 1. Enter the vehicle and turn the ignition ON. 2. Turn the audio unit on and listen for any unusual sounds from any of the speakers. 3. Pull the hood release lever. 4. Open the Driver’s window fully to retain access to the inside of the vehicle. 5. Turn the ignition OFF. 6. Exit the vehicle and close all the doors. 7. Wait at least 2 minutes before proceeding further. 8. Open the hood and remove the PDI (backup power) fuse. 9. Turn the ignition back on and listen again for any unusual sound from any of the speakers. 10. If the unusual sounds heard originally can no longer be verified, replace the amplifier with an exchange unit. If unusual sounds persist while the fuse is removed, there is another cause which will require further diagnosis. After confirming the symptom(s) as outlined in the Introduction above exists, order the applicable replacement amplifier following the Audio Exchange Program instructions. Install the exchange unit following the current Service Manual procedure. NOTE: All exchange amplifiers have the new software and circuitry installed.
