Section 235 (Starting System (Service Information)): Operation: Operation
WARNING: This page is about a different car, the 2013 Jeep Patriot and 2013 Jeep Compass. However, it is still accessible from the selected car via links, so may be relevant.
These components form two separate circuits. A high amperage circuit that feeds the starter motor up to 300+ amps, and a control circuit that operates on less than 20 amps.
The PCM controls a double start over-ride safety that does not allow the starter to be engaged if the engine is already running.
