Tachometer
The tachometer is located on the left side of the instrument panel and displays the engine speed up to 8000 rpm in petrol versions and up to 6000 rpm in diesel versions. The tachometer is controlled by the engine speed signal, which comes from the crankshaft position sensor (CKP). This signal is transmitted on the high speed CAN bus by the engine control module (ECM). The CJB serves as a gateway and transmits the engine speed signal to the instrument cluster via the medium speed CAN bus. The signal is received by the instrument panel microprocessor, which controls the tachometer.
Engine temperature gauge
The engine temperature gauge is located in the center of the instrument panel and is controlled by messages on the medium speed CAN bus from the CJB. CJB receives engine coolant temperature signal (ECT) from ECM via high speed CAN bus when vehicle enters power mode 6 (ignition on). Different positions of the arrow correspond to their temperature values.
Engine coolant temperature,°C (°F) | ||
Petrol | Diesel | Arrow position |
Ignition off | Ignition off | parking gear |
40 (104) | 40 (104) | Cold (blue sector) |
75 (167) | 75 (167) | Start of normal mode |
119 (246) | 113 (235) | End of normal mode |
125 (257) | 118 (244) | Start of overheating (red segment) |
130 (266) | 123 (253) | End of overheating |
If the ECT signal rises above 118°C on diesel vehicles or 127°C on petrol vehicles, the instrument cluster will illuminate the ECT high temperature warning light. If the instrument panel is unable to receive an ECT signal from the CJB, the engine coolant temperature gauge will move to the edge of the overheat zone and the warning lamp will illuminate.
Fuel gauge
The fuel gauge is located in the center of the instrument panel and displays the amount of fuel in the fuel tank when the vehicle is in power mode 6. When the ignition is turned off, the gauge needle returns to its original position.
Two passive magnetic encoders (MAPPS) are located in the saddle type fuel tank, one on each side. The resistance values of both sensors are measured in the CJB through a group of permanent wire connections. The CJB converts both values into medium speed CAN·messages for the instrument cluster. The instrument panel uses these two CAN·messages to calculate the total amount of fuel in both sections of the tank. The instrument cluster will also smooth out the overall fuel value to prevent the pointer from constantly moving due to the movement of fuel in the tank.
The following table shows the approximate fuel level in the tank and the corresponding pointer position.
Fuel quantity, l (US gallon) | ||
Petrol | Diesel | Arrow position |
0 (0) | 0 (0) | Mechanical zero position |
1 (0,2) | 2,5 (0,6) | Below empty tank status |
2,8 (0,7) | 3,8 (1) | Empty tank indication |
11,9 (3,1) | 10,3 (2,7) | Turning on the low fuel warning light |
13,9 (3,7) | 12,3 (3,2) | Turning off the low fuel warning light |
16,9 (4,5) | 16,7 (4,4) | quarter tank |
33,8 (8,9) | 33,4 (8,8) | half tank |
50,8 (13,4) | 50 (13,2) | Three quarters of a tank |
66,9 (17,7) | 68 (18) | Full tank indication |
70,5 (18,6) | 70,5 (18,6) | Overflow |
If the instrument cluster is unable to receive a fuel level signal from the CJB, the fuel gauge needle will move to the empty position and the low fuel warning light will come on.
Speedometer
The speedometer is located on the right side of the dashboard and has three versions:
- Large scale - miles per hour, small scale - km / h
- Large scale - km/h, small scale - miles per hour
- Large scale only - km/h
The speedometer is controlled by signals transmitted over the medium speed bus from the CJB. The vehicle speed signal is sent to the CJB from the ABS module (anti-lock brakes) over the high speed CAN bus and is the average of all four wheel speed sensor signals.
The speedometer also contains an odometer. For more information, see the chapter: Information and Message Center (413-08 Information and Message Centre, Description and Operation).
