I was driving on a highway when my Jaguar just cut out on me. Only the headlights and windows work now. No other accessories will even turn on, and there is no display on the dash, so I am unable to see any warning lights or codes. No activity at all from the engine when trying to start it. Battery is good, alternator is good. Do I need a new ECM/ECU? What else could cause it to just die like that?
