Verifying Repairs: Notes

WARNING: This page is about a different car, the 2003 Mitsubishi Montero Sport. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Erasing DTCs will also erase freeze frame data and reset readiness test status.

Procedure for verifying repairs depends on scan tool functions and whether DTC is set by one-trip or two-trip fault detection logic. Two-trip fault detection logic requires fault be detected on 2 consecutive drive cycles, in which each meet code set criteria, before DTC will set and MIL will illuminate. DTCs using one-trip fault detection logic set DTC the first time fault is detected. If fault is emissions related, PCM will also turn on MIL. Most DTCs use two-trip fault detection logic. To determine which logic is used to set DTC, see DIAGNOSTIC TROUBLE CODE DEFINITIONS under DIAGNOSTIC TROUBLE CODE DEFINITIONS. Then, go to appropriate repair verification procedure.
