• 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
→
2
→
3...38
→
39 after returning to the normal condition whenever ignition switch OFF
→
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.
