1. A starting system for an internal combustion engine, comprising:
- an energy supply device;
a starting device connected to the engine and the energy supply device; and
a controller connected to the engine, the energy supply device, and the starting device, the controller being configured to;
cause the energy supply device to supply current to the starting device;
monitor at least one characteristic of at least one of the energy supply device and the starting device after current is supplied to the starting device; and
diagnose at least the starting device based on the at least one monitored characteristic.

Abstract
A starting system for an internal combustion engine includes an energy supply device, a starting device connected to the engine and the energy supply device, and a controller connected to the engine, the energy supply device, and the starting device. The controller is configured to cause the energy supply device to supply current to the starting device and monitor at least one characteristic of at least one of the energy supply device and the starting device after current is supplied to the starting device. The controller is also configured to diagnose at least the starting device based on the at least one monitored characteristic.
