Instrument Cluster - Conventional Display

The Instrument Cluster (IC) receives a permanent power supply from the vehicle battery via the Rear Junction Box (RJB). A hardwired Light Emitting Diode (LED) security system status indicator is connected to the IC from the Body Control Module/Gateway Module (BCM/GWM) assembly.

The speedometer is driven by square wave signals derived from the wheel speed sensors and the Anti-lock Brake System (ABS) control module. The signal is received on the High Speed (HS) Controller Area Network (CAN) chassis systems bus.

The tachometer is driven by an engine speed signal from the Crankshaft Position (CKP) sensor which is hardwired to the Powertrain Control Module (PCM). The PCM transmits the signal from the CKP sensor to the Body Control Module/Gateway Module (BCM/GWM) assembly via FlexRay bus. The IC receives the signal from the BCM/GWM assembly via HS CAN comfort systems bus.

The Electric Steering Column Lock (ESCL) is connected directly to the IC on a hardwired connection. The IC provides a controlled ground for the ESCL. The steering wheel switchpack inputs are sent to the IC via the Local Interconnect Network (LIN) connection. For additional information, Refer to: STEERING COLUMN

Other vehicle sensors are connected to the BCM/GWM assembly which processes the signals from the sensors. The processed signals are delivered to the IC on the High Speed (HS) Controller Area Network (CAN) chassis systems bus and the HS CAN comfort systems bus. The IC communicates with the vehicle infotainment system on the HS CAN comfort systems bus.
