DESCRIPTION
The Powertrain Control Module (PCM) Reset allows the scan tool to command the PCM to clear all emission-related diagnostic information. When resetting the PCM, a DTC P1000 will be stored in the PCM until all the OBD II 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 Drive Cycles.
The following events occur when a PCM reset is performed:
- Clears the number of Diagnostic Trouble Codes (DTC).
- Clears the DTCs.
- Clears the freeze frame data.
- Clears oxygen sensor test data.
- Resets status of the OBD II system monitors.
- Sets DTC P1000.
