The computer is in the truck, under the drivers side panel behind the drivers seat. There is a button in the computer that when pushed will cause a red or green light to flash. This will be the code. Keep track of how many flashes, and you might actually find a problem. 55 displayed means everything is OK. If that happens, and the truck is running poorly or not at all, I suggest a gallon of gas and a lighter. ( I have an 88 Pathfinder, I KNOW... ) Resist the urge to use a hammer.....
