NOTE: 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
→ 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.
