Clear the Continuous DTCs and Reset the Emissions Monitors Information In the PCM

CLEAR THE CONTINUOUS DIAGNOSTIC TROUBLE CODES (DTCS) AND RESET THE EMISSION MONITORS INFORMATION IN THE POWERTRAIN CONTROL MODULE (PCM)

Description

NOTE: Clear the continuous diagnostic trouble codes (DTCs) and reset the emission monitors information in the powertrain control module (PCM) was previously called PCM reset.

All on board diagnostic (OBD) diagnostic tools support the clearing of continuous DTCs and resetting of emission monitors information in the PCM.

The clearing of the continuous DTCs allows the diagnostic tool to command the PCM to clear/reset all emission-related diagnostic information. While carrying out this operation a DTC P1000 will be stored in the PCM until all the OBD system monitors or components have been tested to satisfy a drive cycle without any other faults occurring. For more information about a drive cycle, refer to On Board Diagnostic (OBD) Drive Cycle. On-Board Diagnostic (OBD) Drive Cycle

The following events occur when the continuous DTCs and emission monitors information is cleared from the PCM:
- Clears the number of DTCs.
- Clears the DTCs.
- Clears the freeze frame data.
- Clears the diagnostic monitoring test results.
- Resets the status of the OBD system monitors.
- Sets DTC P1000.
