1999 Mercury Sable V6-3.0L DOHC VIN SFACTORY OEM SERVICE PROCEDURE
Powertrain Control Module (PCM/KAM Reset)
All OBDII scan tools support the 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.
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.
NOTE: When using the New Generation Star (NGS) Scan Tool to perform a PCM reset, press the CLEAR button. This function is performed only after retrieval of continuous DTCs.
New Generation Star and Generic Scan Tool
Refer to the scan tool manufacturer's manual for specific instructions on how to perform PCM reset.
