Does the JB4 connect to the CAN wires? I would assume it does since it has a CAN clear feature built into it. You NEED to disconnect those CAN wires. Setting it to Map 0 will not be enough. Atleast not for the Procede, I know this for a FACT. As soon as the CAN wires are disconnected the ISID can read and program the car as it normally would.
