How to Read DTC and 1st Trip DTC

WARNING: This page is about a different car, the 2012 Infiniti G25. However, it is still accessible from the selected car via links, so may be relevant.

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.
