You wouldnt happen to have a Procede or JB on the car would you?
With the Procede you need to disconnect the CAN wires from the Procede to factory connection or the machine will not detect the car or VIN. Earlier JBs you do not need to do anything, not sure if the JB4 taps into CAN wires. If it does, remove the CAN wires. You can leave the rest of the stuff connected however.
