  • *2: If the power connector is disconnected after the hybrid system was started, 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 hybrid system is started and the power switch is pressed 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.
