Abstract
A remote start system for a vehicle having an engine, and a vehicle data communications bus extending throughout the vehicle may include at least one external temperature sensor coupled to the vehicle data communications bus to sense an external vehicle temperature, and at least one internal temperature sensor coupled to the vehicle data communications bus to sense an internal vehicle temperature. The remote start system may also include a wireless remote control device and a controller coupled to the vehicle data communications bus to start the engine based upon the wireless remote control device and determine an idle time threshold based upon the external temperature. The controller may also stop the engine based upon reaching the idle time threshold or an internal vehicle temperature threshold.
