Tech Tips

*1: Even if no fault is present, this DTC may be stored depending on the battery condition or engine start voltage.
*2: If the power connector is disconnected after the engine starts, this DTC is stored after 180 seconds.
*3: If the device is reported as not existing during verification, check the power source circuit and AVC-LAN circuit for the device.
*4: This DTC may be stored if the engine is started and the power switch start again.

Note

Before starting troubleshooting, be sure to clear the 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 assembly is the master unit.
Be sure to clear and recheck for the DTCs after the inspection is completed to confirm that no DTCs are output.
