Ward D

Son was using truck yesterday in inclimate weather , on trip home he said the service messages for trailer brakes , ABS, service 4x4 , and stabilitrak came on , vehicle then would not let him get over 30 /hr. Today will not fire up or dash or radio will not fire up and won't start. Put a booster on got the dash lights on , with all the messages there , radio fired up but will not even crank. Step son brought out his little e diagnostic OBD tye reader that you use with a phone app and it will not connect. Any ideas ??
