Trip counter
The microprocessor in the instrument panel calculates the route data based on the transmission of wheel speed signals from the anti-lock brake system module (ABS) via high-speed CAN bus. The CJB serves as a gateway and transmits the wheel speed signal to the instrument cluster via the medium speed CAN bus.
The trip meter shows the distance traveled since the last reset of the trip odometer. The trip odometer can be reset by pressing and holding the trip computer button for more than 1 second. The trip odometer can show distance traveled up to 999,999 miles or kilometers. When this value is exceeded, the trip odometer starts counting again from 0 miles or kilometers.
Route data is stored in RAM (RAM) instrument panel and will be lost if the battery is disconnected.
Average fuel consumption
The instrument panel receives two fuel tank level readings on the medium speed CAN bus via the CJB. The instrument panel calculates the average value of the amount of fuel used in the tank based on two signals. Every 200m the vehicle has been moved, the instrument panel recalculates this value to determine how much fuel has been used. This value is then averaged over the last 50 kilometers of travel and displayed in the trip computer.
The mileage signal is initiated in the ABS module and received by the instrument cluster, passing through the CJB on the medium speed CAN bus.
Remaining distance to refuel
Distance to refueling is calculated using the average fuel consumption (see above) and the value of the fuel level in the tank. By dividing the fuel level in the tank by the average fuel consumption, the instrument panel can calculate the distance the vehicle can travel with the current amount of fuel in the tank before it needs to refuel.
Average speed
The average speed signal is calculated using the vehicle speed signal supplied by the CJB on the medium speed CAN bus. This signal is initiated in the ABS module and is the average of the four wheel speed signals. To calculate the average vehicle speed, this value is divided by the time counted from the last reset of the trip computer.
