Starting System - with Intelligent Access (IA)
Overview
The starter system controls the starting of the vehicle. The starter is enabled by the starter relay when the relay is activated by the PCM (Powertrain Control Module). The PCM (Powertrain Control Module) receives inputs from the start/stop switch, BCM (Body Control Module) and TR (Transmission Range) sensor before activating the starter relay to crank the engine.
Remote Start
The remote start feature allows the operator to remotely start the engine from up to 100 meters (328 feet) away and is activated using the IKT (Integrated Keyhead Transmitter). Once started, the engine runs for 10 minutes. The run time can be extended by the operator.
