KOER Switch
The KOER Switch is a functional test performed On-Demand with the engine
running. The test is designed to set DTCs if one or more switches fail to
transition from one state to another (i.e. - cycle ON/OFF). Upon initiating the
test, wait 5 seconds before beginning the driver-operated controls. This
eliminates the possibility of setting false DTCs with the cruise/speed control
switches.
