You don't. You start jumping pins and will cause more problems than you already have. Any big chain type AutoParts store will read them for you. FREE Be it OBD or OBDII take it to the AutoZone PepBoys anything like that

David is right, your truck has the OBDii system and you can only use a code scanner. You can purchase a basic one these days for $20. Only the OBD system 1996 and older vehicles in the US can you use a voltmeter and jumper pins.
