HINT:

*1: This code may be recorded depending on the battery condition or engine start voltage even if no
failure is detected.

*2: If the power connector is disconnected after the engine starts, this code is recorded after 180 se-
conds.

*3: This code may be stored if the ignition key is turned to the START position again with the engine
running.

*4: This code may be stored if the ignition key is held in the START position for 1 minute or more before
returning to the ON position.

*5: If the device is reported as not existing during verification, check the power source circuit and AVC–
LAN circuit for the device.

*6: w/ Rear seat audio system only.
