Instrument Panel Cluster (IPC) - System Operation and Component Description: Tachometer

The tachometer is an analog gauge on the base and optional mid-level IPC. The temperature gauge is a virtual gauge on the optional high-level IPC.

The IPC receives the engine RPM data message from the GWM over the HS-CAN3. The GWM receives the engine RPM data message from the PCM over the HS-CAN1.
