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.
