If the anti-theft light flashes rapidly when you turn the key on to start the truck, you probably need to reset the PCM system. first you'll need to disconnect the negative battery cable as well as the positive cable. The battery should be disconnected for about 30 minutes.You will then need to work on the fuses for the PCM system. In the owner's manual (you can download it if you don't have the manual) locate the diagrams for the fuse box under the hood and the one in the truck cabin. Using the diagram and the identifier list from the manual, check every fuse related to the PCM system by pulling each fuse out one at a time. If the fuse is blown (you'll see that the wire in the fuse is severed), you'll need to replace the fuse with the exact amp fuse. Pulling each fuse out is part of resetting the PCM system. Once all of the fuses are back in place/replaced, reconnect the positive battery cable. You'll then replace the negative battery cable. If the PCM system was reset successfully, the car horn will sound as soon as you reconnect the negative battery cable in a pattern of one long sound followed by 5 shorter sounds. When this happens, push the unlock button on the key FOB and the horn should stop. You should then be able to start the vehicle as normal. Hope this helps!
