*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±
