NOTE: When ordering the applicable exchange amplifiers from United Radio, the exchange units supplied will contain all the latest available enhancements to address the symptoms as listed on pg. 1 of this bulletin.
SERVICE PROCEDURE:
The causes of Symptoms 1, 2, 4, 5, 6 and 7 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. Please refer to Appendix section for troubleshooting reference with “No Sound” concerns.
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.
REMINDER: The exchange units supplied will contain all the latest available enhancements to address the symptoms as listed on pg. 1 of this bulletin. All exchange amplifiers have the new software and circuitry installed.
ADDITIONAL INFORMATION:
REMINDER: Customer satisfaction and retention starts with performing quality repairs.
After the customer concern has been confirmed, the service procedure for replacing the power amplifier assembly remains unchanged. Always refer to the applicable Service Manual and review the full requirements of the repair being performed. The Service Manual procedures contain information critical to performing an effective repair the first time and every time.
Appendix
‘No Audio’ Troubleshooting – Sound does not come out from the speaker(s)
Please Note: Please check the following three points regardless of the results of the defect diagnosis.
1) If “No Sound” is recovered during diagnosis, please specify the condition. (e.g., Remove power, ACC OFF→ON, etc.)
2) Please check the part number of the AMP, and if the part number is old, replace it with the latest part number.
3) Please make sure you can hear any beep. (On the head unit go to Settings→Sound→Beep sounds, turn on BEEP feature )
4) If this is a repeat occurrence for “No Sound” (a previous visit fixed “No Sound” during diagnosis or with a replacement part), please report via QMR

SERVICE PROCEDURE: The causes of Symptoms 1, 2, 4, 5, 6 and 7 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. Please refer to Appendix section for troubleshooting reference with “No Sound” concerns. 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. REMINDER: The exchange units supplied will contain all the latest available enhancements to address the symptoms as listed on pg. 1 of this bulletin. All exchange amplifiers have the new software and circuitry installed.
