Details of time display

• CRNT: Displays when there is a malfunction now or after returning to the normal condition until turning igni-

tion switch OFF 

→

 ON again.

• 1 - 39: Displayed if any previous malfunction is present when current condition is normal. It increases like 1

 ON. The counter

remains at 39 even if the number of cycles exceeds it. It is counted from 1 again when turning ignition switch

OFF 

→

 ON after returning to the normal condition if the malfunction is detected again.
