  • *2: If the power connector is disconnected after the engine starts, this code 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.

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.
