:

• 0: Current malfunction is present

• 1-39: Displayed if any previous malfunction is present when current condition is normal. The numeral value increases by one at each

IGN ON to OFF cycle from 1 to 39. The counter remains at 39 even if the number of cycles exceeds it. However, the counter is reset
to 1 if any malfunction is detected again, the normal operation is resumed and the ignition switch is turned from OFF to ON.
