All OBD-II scan tools support Powertrain Control Module (PCM) reset. The 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. See DRIVE CYCLES in appropriate SELF-DIAGNOSTICS article.
The following events occur when a PCM reset is performed:
- Clears the number of Diagnostic Trouble Codes (DTCs).
- Clears the DTCs.
- Clears the freeze frame data.
- Clears diagnostic monitoring test results.
- Resets status of the OBD-II system monitors.
- Sets DTC P1000.
