Resetting the Keep Alive Memory (KAM)

Resetting Keep Alive Memory (KAM)

Resetting Keep Alive Memory will return PCM memory to its default setting. Adaptive learning contents such as idle speed, refueling event, and fuel trim are included. A PCM Reset (described above) is also part of a KAM Reset. Both can be useful in post repair retest.

After Keep Alive Memory has been reset, the vehicle may exhibit certain driveability concerns. It will be necessary to drive the vehicle to allow the PCM to relearn values for optimum driveability and performance.

This function may not be supported by all scan tools. Refer to scan tool manufacturer's instruction manual.

If an error message is received or the scan tool does not support this function, disconnecting the battery ground cable for a minimum of 5 minutes may be used as an alternative procedure.
