Vehicle Driveability Computer Relearn Procedure
Manufacturer does not provide a specified computer relearn procedure for obtaining proper driveability. If vehicle battery was disconnected or Powertrain Control Module (PCM) was replaced, driving the vehicle 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.
NOTE:
Vehicle Theft Deterrent (VTD) system auto learn procedure must be performed if Powertrain Control Module (PCM), VTD module, ignition lock cylinder, steering column assembly or ignition key are replaced. A password is communicated between VTD module and PCM to provide engine operation. If PCM is replaced, the PCM must learn the password from the VTD module.
