DTC Index

Note. The details of time display are as follows: CRNT: A malfunction is detected now PAST: A malfunction was detected in the past IGN counter is displayed on FFD (Freeze Frame Data). 0: The malfunctions that are detected now CAN communication system (U1000, U1010) 1 - 39: It increases like 0 --> 1 --> 2... 38 --> 39 after returning to the normal condition whenever the ignition switch OFF --> ON. It returns to 0 when a malfunction is detected again in the process. If it is over 39, it is fixed to 39 until the self-diagnosis results are erased. Other than CAN communication system (Other than U1000, U1010) 1 - 49: It increases like 0 --> 1 --> 2... 38 --> 49 after returning to the normal condition whenever the ignition switch OFF --> ON. It returns to 0 when a malfunction is detected again in the process. If it is over 49, it is fixed to 49 until the self-diagnosis results are erased.

Note. With the detection of "U1000" some systems do not perform the fail-safe operation.

A system controlling based on a signal received from the control unit performs fail-safe operation when the communication with the ITS control unit becomes inoperable.
