Resetting Keep Alive Memory (KAM)
Disconnect the negative lead from the battery for a minimum of 5 minutes. Resetting KAM will clear learned values the Powertrain Control Module (PCM) has stored for adaptive systems such as idle and fuel.
After KAM 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.

To clear KAM, disconnect the negative side of the battery for a minimum of 5 minutes.
