DTC IndexINFOID:0000000003775650
*1:
 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 re set
to 1 if any malfunction is detected again, the normal operation is resumed and the ignition switch is turned from OFF to ON. OPERATED PORTION T2
