How to Reset the Service Engine Soon Light on My Nissan

by Alibaster Smith

Your Nissan vehicle comes equipped with a service light which reads "service engine soon." This light warns you that there is a problem with the vehicle's emissions control system. This system is very important as it regulates and controls the air to fuel ratio as well as a number of other vehicle functions. A free diagnostic scan can be done to diagnose the problem at most auto parts stores. When you have diagnosed the problem and fixed it, you need to reset the "service engine soon" light.

Step 1

Open the hood and loosen the retaining nut on the negative battery cable clamp using a socket wrench.

Step 2

Slide the cable clamp off of the negative battery terminal.

Step 3

Wait 5 minutes and reconnect the battery cable and then tighten the retaining nut with the socket wrench.

Step 4

Turn the ignition on and wait for the "service engine soon" light to blink and shut off. This will reset the light on your dash.
