SELF-DIAGNOSIS CHECKING
Self-diagnosis checking is performed when there has been an
automatic cancellation without cancel switch operation.
NOTE
Even when the ignition key is placed in the OFF position, all
diagnosis codes are stored and retained, until the battery cable
is disconnected, to make sure that the problems encountered
in the past can be checked.
