DTC And DTC Of 1ST Trip

DIAGNOSIS SYSTEM (TCM)

DIAGNOSIS DESCRIPTION : DTC and DTC of 1st Trip


2 TRIP DETECTION DIAGNOSIS THAT ILLUMINATES MIL

- The DTC number of the 1st trip is the same as the DTC number.
- When a malfunction is detected at the 1st trip, TCM memorizes DTC of the 1st trip. MIL does not light at this stage. If the same malfunction is not detected at the 2nd trip (conforming to necessary driving conditions), DTC at the 1st trip is erased from TCM. If the same malfunction is detected at the 2nd trip, TCM memorizes
DTC and MIL lights at the same time.
- The DTC of the 1st trip is specified in Service $01 of SAE J1979/ISO 15031-5. Since detection of DTC at the
1st trip does not illuminate MIL, warning for a problem is not given to a driver.
- For procedure to delete DTC and 1st trip DTC from TCM, refer to "CONSULT Function" CVT RE0F10D.
- If DTC of the 1st trip is detected, it is necessary to check the cause according to the "Diagnosis flow". Refer to "Flowchart of Trouble Diagnosis" Flowchart Of Trouble Diagnosis.
