How to Reset the Service Light on a 2003 Nissan Sentraby Katebo
Your 2003 Nissan Sentra comes equipped with an On-Board Diagnostics computer that keeps track of when your vehicle needs servicing and alerts you by illuminating the "service engine soon" light on the instrument panel. This light tells you that there may be a problem with the emission control system on the car. An auto-parts retailer can do a free diagnostic reading of the trouble code using a scanner. After you have diagnosed and fixed the problem, you can manually reset the light yourself.
Pop up the hood of the car and locate the battery. The negative terminal has a black plastic covering. Find the negative battery clamp . Loosen the nut a bit using a 10 mm open-end wrench.
Remove the clamp from the battery terminal. Take care not to let it touch the positive side of the battery or cable.
Wait about 10 minutes, then reattach the negative battery cable to the negative side of the terminal and tighten the nut with the wrench.
Put the key into the ignition and wait for the service light to flash on the instrument panel, then shut off the engine. The light is now reset.
