How to Read DTC and 1st Trip DTC

DTCs and 1st trip DTCs related to the malfunction are displayed in "Self-diag results".

• When ECM detects a 1st trip DTC, "1t" is displayed for "TIME".
• When ECM has detected a current DTC, "0" is displayed for "TIME".
• If "TIME" is neither "0" nor "1t", the DTC occurred in the past and ECM shows the number of times the vehicle has been driven since the last detection of the DTC.
