Speedometer
The speedometer is controlled by the 5V stabilizer circuit/controller area network controller in the gauge control module. The 5V stabilizer circuit/controller area network controller in the gauge control module receives vehicle speed information from the PCM through the fast controller area network (F-CAN) data lines. The 5V stabilizer circuit/controller area network controller sends vehicle speed information through a dedicated data line to the speedometer in the gauge control module, which displays the vehicle speed.
