OBD-II Drive Cycle & Diagnostic Trouble Codes

WARNING: This page is about a different variant/trim than selected.

NOTE: A trip does not have to be completed to set DTC in memory.

A Diagnostic Trouble Code (DTC) will be stored in PCM memory after a malfunction is first detected. A DTC will be erased from the PCM's memory after 40 engine warm-up cycles without the malfunction being detected after the MIL is turned off. Another method of erasing the DTC is initiating a PCM reset. DTC memory storage requirements vary with each monitor. See appropriate monitor under ON BOARD DIAGNOSTIC II MONITORS .
