Fault code display
Continuance operation : DTC code is one.
Continuance operation : DTC code is more two.
STEP operation
Nomal or one fault code is same as a continuance operation.
DTC code os more two.
If fault codes are displayed during the check, Inspect malfunction causes by referring to fault codes.
