How to Turn Off a Check Engine Light on a Nissan

Updated April 17, 2017

Nissan cars have become more technologically advanced in recent years. ECU (Engine Control Unit) computers are now an integral part of Nissan car design. The ECU constantly monitors and governs many functions, including the electrical and safety systems of the car, and engine management. When this unit detects a problem, the SES (Service Engine Soon) light on the dashboard turns on to indicate that there's an issue that needs attention. When you take your car in for repair, mechanics can then read codes from the ECU to determine what specific problems exist. After repairs are complete, the SES light must be reset. The SES light in a Nissan is frequently called a check-engine light in other makes.

  1. Open the driver's side door and get into the drivers seat.

  2. Insert the key into the ignition and turn it a quarter turn so the ignition turns on, but the engine doesn't start.

  3. Step on the accelerator and quickly release it. Do this 5 times in less than 5 seconds. When you step on the pedal, press it down as far as it can go.

  4. Wait 10 seconds.

  5. Press the accelerator completely down with your foot and hold it there for 10 seconds, or until the SES light blinks on and off.

  6. Step on the accelerator and hold it down completely for another 10 seconds and then release it.

  7. Turn the ignition key to the off position.

  8. Wait 3 minutes for the ECU to automatically reset.

  9. Start your engine. This will reset the SES light.

  10. Tip

    This method for resetting the check engine light works on any Nissan model.

    Warning

    Consider taking your Nissan to a mechanic to check your car before resetting the check engine light yourself. Otherwise, the codes he needs may be lost.
