Clearing Keep Alive Memory (KAM) and Relearn Procedure

The Electronic Control Assembly (ECA) stores information about vehicle operating conditions and uses this information to compensate for component tolerances. When an emission related component is replaced, Keep Alive Memory (KAM) should be cleared to erase the information stored by the processor from the original component.

To clear the KAM, disconnect the battery negative terminal for five minutes or more. Drive the the vehicle for at least ten miles to allow the ECA to relearn the values for optimum performance.
NOTE: During the ten mile relearn drive, the vehicle may exhibit some driveability symptoms. These should be eliminated when the KAM has relearned the operating values.
