A stepper motor is a brushless, synchronous electric motor that converts digital pulses into mechanical shaft rotation. One digital pulse to a stepper motor drive or translator causes the motor to increment one precise angle of motion.
How do I reset my CVT transmission?
Models
- Turn AC off.
- Move the shift selector to the Park position, turn ignition off, then wait 5 seconds.
- Start the engine and allow it to idle for 5 seconds.
- Turn the ignition off and wait 30 seconds.

- Restart the engine.
What is a step motor Nissan?
THE STEPPER MOTOR. Look for Jatco CVTs in Nissan, Dodge, Jeep, and other vehicles. To keep it simple, the stepper motor can extend or retract, moving the position of the ratio control valve. The transmission control module knows that the stepper motor controls the ratio.
How can be step angle is calculated?
Step angle of the stepper motor is defined as the angle traversed by the motor in one step. To calculate step angle,simply divide 360 by number of steps a motor takes to complete one revolution.
What is the difference between full step and half step?
A. In full-step two phases are on and in half-step only one phase is on.
What are the possible causes of error code P1778?

What does a stepper motor do?
The stepper motor has nothing to do with pump output which cannot be blocked other than by a pressure regulator. The stepper actually controls the spread of the primary pulley halves to change the effective gear ratio as needed. It is basically the shift control there.
How does a step motor work on a Toyota Corolla?
The step motor’s 4 aspects of ON/OFF change according to the signal from the Transmission Control Module (TCM). As a result, the flow of line pressure to the primary pulley is changed and the pulley ratio is controlled. This diagnosis item detects when the electrical system is OK, but the mechanical system is NG.
