• Throttle Body has been cleaned or removed and reinstalled
• Accelerator Pedal has been removed and reinstalled
• After Engine and/or Automatic transmission repairs
• Fault codes have been cleared

Special Notes

• It is normal for there to be no explicit instructions or changes on the screen when you do the above procedure. The transmission controller does not provide any feedback that it has been successfully performed. Checking the measuring block readings after the procedure should confirm a change at 95 - 100% pedal position.
  

• If the pedal did not travel to the floor due to an obstructions such as too many floor mats the procedure may not be successful.
  

• If faults are stored in the Engine or Transmission for throttle related problems, the procedure will not be successful.
  

• When the vehicle is equipped with an engine using the Drive-by-Wire (DBW) throttle system the Engine Control Module may support a Kick-Down Basic Settings as described in the next procedure.
