Vauxhall Ampera CAN hacking

Remote Start

The purpose of this project is to enable a 'remote start' or 'preheat' feature on the Vauxhall Ampera. The US equivalent of this car, the Chevrolet Volt has this functionality through OnStar. Unfortunately, the Vauxhall version was not lucky enough to have access to this service, and so we will need to do it ourselves.

The remote start function is accessed through the low speed single wire GMLAN bus, on pin 1 of the drivers side (main) OBD2 port [1].
