Digital Input Signals

Digital Input Signals
The normal ignition switch terminals (KLR, KL15 & KL50) are input to the cluster. Various functions are dependent on ignition switch position.




Steering Column Switch - The turn signal stalk provides a momentary ground signal that is used to call up BC functions.

Brake Pad wear Sensor - The pad sensor inputs are used to illuminate the brake pad warning indicator.

Instrument Panel Button - The reset button is used to reset the trip - odometer as in the past. It will also display the mileage, if pressed with the key switched OFF. This button is also used for the Base BC/instrument cluster test functions.

Inputs for Warning Lamps - Various switches are used to signal the cluster for warning and indicator lamp illumination. Many of these inputs are provided over the CAN or K-bus.
