Description And Operation: Operation
All analog gauges in the Base and the Premium Instrument Panel Cluster (IPC) receive battery current on the IPC printed circuit board only when the status of the ignition switch is ON. When the status of the ignition switch is OFF, battery current is not supplied to any gauges and the IPC is programmed to move all of the gauge needles back to the low end of their respective scales. Therefore, the gauges do not accurately indicate any vehicle condition unless the status of the ignition switch is ON.
Each of the analog IPC gauges contains an electronically controlled stepper motor unit. The IPC circuitry completely controls the activation and deactivation of these stepper motors to position each gauge needle in the appropriate position based upon IPC programming and electronic messages received from other electronic modules in the vehicle over the Controller Area Network (CAN) data bus.
