*1

 The AMP device records that the AMP output does not function even while the source device operates.

Tech Tips

*1: Even if no fault is present, this trouble code may be stored depending on the battery condition or engine start voltage.

Note


  • Before starting troubleshooting, be sure to clear DTCs stored due to the reasons described in the HINT above. Then, check for DTCs and troubleshoot according to the output DTCs.


  • The radio receiver is the master unit.


  • Be sure to clear and recheck DTCs after the inspection is completed to confirm that no DTCs are output.
