You see the tool trucks where you live, snap on, mac tools, matco, cornwell, etc....I'd try one of them, just keep in mind a code puller is only that,so it only pulls codes, it doesn't do diagnostics. You cant diagnose vehicles these days with just a hand held auto zone code reader, that is why 90 percent of their diagnosis' are wrong.
