Circuit/System Description

The driver information center switches are multiplexed switches that are part of the Turn Signal/Multifunction Switch.

The Instrument Cluster provides 5 volts to the MENU switch. The MENU switch is a momentary contact switch that is provided ground through the Turn Signal/Multifunction Switch ground circuit.

The Instrument Cluster provides battery voltage to the UP, DOWN, SET switches. The UP, DOWN, SET switch signal circuits are pulled up to battery voltage in the Instrument Cluster. The Instrument Cluster also provides the UP, DOWN, SET switches with a low reference circuit. The UP, DOWN, SET switch signal circuit is pulled low when a switch is activated. The driver information center UP, DOWN, SET switches are momentary contact switches that connect a series of resistors in a resistor ladder format. The instrument cluster monitors the driver information center UP, DOWN, SET switch signal circuit to determine the switch position. Each switch state - UP, DOWN, SET- corresponds to a certain resistance value. The instrument cluster determines the switch pressed by the voltage drop across the resistors.
