DESCRIPTION

DTC TROUBLE DETECTION CONDITION

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 the device is reported as not existing during verification, check the power source circuit and
AVC-LAN circuit for the device.
