CLEARING DIAGNOSTIC TROUBLE CODES
Using Scan Tool
Connect scan tool to Data Link Connector (DLC), located under left side of instrument panel. Turn ignition on. Using screen prompts on scan tool, clear codes from Powertrain Control Module (PCM).
After 3 good trips, PCM will turn off the MIL. At that time, the PCM will automatically switch the trip counter to a warm-up cycle counter. The PCM will erase DTCs after 40 warm-up cycles if the recent malfunction does not reoccur in that time.
Clearing Diagnostic Trouble Codes (DTC) with a scan tool will also erase all OBD-II monitor data. This includes all counter information for warm-up cycles, trips and freeze frame data.
