    Continuously Variable Transmissions (CVT) in Nissan vehicles are designed to provide smooth and efficient power delivery.

    Like any sophisticated system, the CVT can sometimes experience issues that may require a reset to restore optimal performance.

    Resetting the CVT on a Nissan can help resolve problems related to transmission behavior, shifting anomalies, or other performance issues. 

    What Does CVT Mean on Nissan

    A Continuously Variable Transmission (CVT) is designed to optimize engine performance and fuel efficiency. Instead of using fixed gears, a CVT employs a pair of variable-width pulleys connected by a flexible belt or chain. These pulleys can change their diameter continuously, allowing the transmission to adjust to the most efficient gear ratio for any given driving condition.

    Variable Pulleys: The primary components of a CVT are the input and output pulleys. The width of these pulleys can vary, effectively changing their diameter.

    Flexible Belt or Chain: A strong, flexible belt or chain runs between these pulleys, transmitting power from the engine to the wheels.

    Seamless Adjustment: As the pulleys adjust their widths, the belt or chain moves to different positions, creating an infinite number of gear ratios. This allows the engine to operate at its optimal RPM for fuel efficiency and power.

    How to Reset CVT

    Step 1: Disconnect the Battery

    Open the hood and locate the battery, usually found on the driver’s side of the engine bay.

    Using a wrench, loosen the nut on the negative battery terminal (marked with a minus sign). Carefully remove the cable from the terminal to disconnect the power supply.

    Allow the vehicle to sit without power for at least 10 minutes. This helps clear any residual charge in the system and ensures a full reset.

    Step 2: Reconnect the Battery

     After the waiting period, reattach the negative battery cable to the terminal. Tighten the nut securely to ensure a good connection.

    Without starting the engine, turn the ignition key to the "ON" position. This step powers up the vehicle’s electronics without cranking the engine.

    Allow the vehicle’s electronic systems to initialize. This process takes about 5 seconds.

    Step 3: Perform the Accelerator Pedal Reset

    With the ignition in the "ON" position, fully depress the accelerator pedal to the floor. This action signals the TCM to enter the reset mode.

    Keep the accelerator pedal fully depressed for approximately 10 seconds. This period allows the TCM to recognize the reset command.

    After 10 seconds, release the accelerator pedal completely. This step finalizes the reset command.

    Turn the ignition key to the "OFF" position and remove the key from the ignition. This step completes the reset process.

    Step 4: Start and Idle the Engine

    Insert the key into the ignition and start the engine. Allow it to idle for a few minutes without pressing the accelerator pedal. This idle period lets the TCM recalibrate and adjust to its default settings.

    Ensure the engine idles smoothly without any unusual noises or vibrations. This observation helps confirm that the reset process was successful.

    Step 5: Road Test the Vehicle

    Take the vehicle for a short drive, starting with gentle acceleration. Allow the CVT to adjust through its range of ratios. Avoid aggressive driving during this initial phase to let the TCM recalibrate properly.

    Pay close attention to how the transmission behaves. The reset process should have cleared any minor issues and restored smoother shifting. If the CVT performs well, the reset was successful.

    Step 6: Verify the Reset with  Car Scanner

    If you have access to car scanner, connect it to the diagnostic port, usually located under the dashboard on the driver’s side.

    Use the scanner to check for any stored error codes. If no codes are present, the reset was successful. If codes persist, further diagnostics may be required.

    Tips for Maintaining Your Nissan CVT

    Follow the manufacturer’s recommended maintenance schedule, including fluid changes and inspections.

     Always use Nissan-approved parts and fluids to ensure optimal performance and longevity.

    Avoid overloading your vehicle, as excessive weight can strain the CVT and reduce its lifespan.

    Smooth and consistent driving can help maintain the health of your CVT. Avoid abrupt acceleration and deceleration whenever possible.


    Resetting the CVT on your Nissan can be a straightforward process that helps restore the transmission’s optimal performance. If you continue to experience issues after performing the reset, it’s best to consult a qualified Nissan technician for a thorough inspection and repair.
