    2002 nissan altima service engine soon light
    Good day, I am looking for some info on how to reset my service engine soon light. It came on the other day and I would like to reset it and see if it will come back on before I take it to my mechanic. If any could help me out with this I would be grateful.

    Thanks

    This is how you find out why your Service Engine Soon (SES) light is on and how to reset it. No tools required!

    In car ECM Diagnostics/ECM Reset procedure:

    1) Sit in the driver's seat.
    2) Turn the ignition key to the ON position and wait three seconds. (Do not start the car.)
    3) Fully depress and release the accelerator pedal five times in less than five seconds.
    4) Wait exactly seven seconds. Fully depress the accelerator pedal for ten seconds until the SES light flashes.
    5) Release the accelerator pedal and start counting flashes to obtain the four-digit trouble code.
