Vehicle Driveability Computer Relearn Procedure
Manufacturer does not provide a specified computer relearn procedure for obtaining proper driveability. If vehicle battery is disconnected for more than 5 minutes or Powertrain Control Module (PCM) is replaced, driving the vehicle 10 miles or more will enable the PCM to perform a computer relearn procedure for obtaining proper driveability. Inform customer that driveability may differ from what they are accustomed to until the PCM completes the computer relearn procedure.
