HINT: 1: Even if no fault is present, this trouble code may be stored depending on the battery condition or engine start voltage. 2: If the power connector is disconnected after the engine starts, this code is stored after 180 seconds. 3: If it is reported that the device does not exist during verification, check the power source circuit and AVC-LAN circuit for the device. 4: This code may be stored if the engine is started and then started again.

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