 The AMP device records that the AMP output does not function even while the source device is operating.
Tip:

*1: This code may be stored if the engine is started and then started again.

*2: 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 to erase codes stored due to the reasons described in the HINT above. Then, check for DTCs and troubleshoot according to the output DTCs.

  • The navigation receiver assembly is the master unit.
