Code ScannerA code scanner will help you determine what is wrong with your truck by talking to the ECU, so this is a valuable tool. Luckily, Actron makes one for every budget, from a simple $20 unit, all the way up to a $500-plus scanner. How much you plan on working on OBD-1 and -2 vehicles should help you decide which scanner is right for you. Unfortunately, in the smartest move of the weekend, I disconnected the battery for more than an hour, which cleared the ECU of any stored codes, so I never got to read them.
