Digital Speedometer

NOTE: The digital speed displayed can differ slightly from the analog speedometer due to stepper motor-pointer movement, indication tolerances and gauge bias.

The IPC provides a redundant digital speedometer display in the message center. The IPC utilizes software that modifies the display to account for differences between the speedometer gauge indication and the digital display resulting from built in biasing of the indication and tolerances in speedometer stepper motor/needle movement. The IPC receives the cruise control set speed display message from the GWM over the HS-CAN3. The GWM receives the cruise control set speed display message from the PCM over the HS-CAN1.
