Aerostar 2WD V6-182 3.0L (1995)
Powertrain Control Module: Reset Procedure
KEEP ALIVE MEMORY AND ADAPTIVE STRATEGY
The EEC-IV system constantly monitors and adjusts the PCM calibration to correct for normal wear and aging of components. The PCM uses
these calibration adjustments to shift fuel delivery calculations and idle speed specifications to compensate for the aging of the vehicle.
When an Electronic Engine Controls (EEC) system component is replaced, the Keep Alive Memory (KAM) should be cleared to erase the
information stored by the processor from the original component.
CLEARING KEEP ALIVE MEMORY
To clear the KAM, disconnect the battery negative terminal for five minutes or more (preferably 15 minutes).
ADAPTIVE STRATEGY RELEARN PROCEDURE
After repairs have been made and the KAM cleared drive the the vehicle for at least ten miles to allow the PCM 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.
