How can you reset the service engine soon light for the 2003 Infiniti QX4 SUV?

Answer 1

If everything seems to be working fine, then it is just a reminder to change the timing belt which is critical. The light is programmed to come on at certain mileage intervals usually around 80,000 then again somewhere between 150,000 and 160,000. The point being that you take it to the factory and have it checked out for any possible emissions or ignition type issues. But if your vehicle's mileage is not close to either one of these milestones then I would suggest you take it to the dealer or another reputable shops because you have issues. The only real way to have the code cleared is to take it to a mechanic with a code reader. I've heard that you can sometimes reset that code by disconnecting the battery cables for a minute then reconnecting, the idea is that it "resets" everything back to factory settings. I personally haven't found it to work but it's worth a shot.
