The UPD (User Programmable Driver) is a sophisticated semiconductor inside the ECM. It is "programmable" because the Toyota engineers can set specific current limits (e.g., 0.5A to 2.0A) for each actuator.

Service Completed Successfully. Recommendation: The transmission fluid is a vital component for the longevity of the CVT or Torque Converter unit. It is recommended to perform this service every 40,000km to 60,000km (or as per the specific owner's manual for severe driving conditions) to prevent transmission jerking or failure. The UPD (User Programmable Driver) is a sophisticated
