Question about JVC KD-AVX40 Car Video Player
There is obviously something that is grounding the power for critical communcation systems for the vehicle (all of the trouble codes are for lost communication with a sensor... one of the codes was for lost communication with the dash cluster) when the radio wiring harness is connected. The check engine light will remain on after the harness is disconnected because the codes have triggered the light to stay on until it is reset at ecm by an onboard scanner or negative battery cable is disconnected for 15 minutes to clear the code. You will need to get a correct wiring diagram that describes the color coding for each wire and what the wires are for. The radio should only be connected to the speakers, 12 volt keyed(switched), 12 volt constant, and radio should be grounded directly(not thru wiring harness). I would try disconnecting the ground wire(black) from the wiring harness and ground it directly to a good ground on the vehicle and see if that allows the vehicle to start & radio works.
