Instrument Cluster

The instrument cluster contains analog displays as well as warning and control lamps for displaying the system status; in addiiton, there is an LCD indicator field for driver information.

The instrument cluster receives the following signals from the PCM via the high speed CAN (controller area network) Bus (HS-CAN):

Vehicle speed

  • The PCM receives the necessary signals from the ABS (anti-lock brake system) wheel sensors from the ABS control unit on the HS-CAN.

Engine Coolant Temperature

Engine oil pressure.

Engine speed

The instrument cluster receives the following signals from the GEM via the medium speed CAN Bus (MS-CAN):

  • Ambient temperature
  • Brake fluid level
  • Handbrake control
  • Door latch control
  • Liftgate latch control
  • High beam control
  • Headlamp flasher control
  • Direction indicator control

The fuel level signal is sent by the two fuel level sensors in the fuel pumps in the semitrailer tank, which is wired to the instrument cluster. The sensors are connected in series, and the total resistance is determined from the two individual resistors. The instrument cluster converts the raw fuel level signal into a damped fuel level value.

The odometer shows the total distance travelled by the vehicle and is based on the same signal as is processed for the daily mileage counter. The value is recorded by the instrument cluster and stored in a protected EEPROM (Electronically Erasable Programmable Read Only Memory) area.

This area is a memory protected against manipulation. If the instrument cluster detects an error in this memory area, e.g. through damage, the driver is notified with the "Odometer error" message.

Message center

The message center is operated using the left-hand switch on the steering column.

The SET/RESET button is activated to select a submenu and change the settings. If signal tones have been activated, a short acoustic signal will sound each time a button is pressed.

By turning the rotary switch, the different menu displays can be scrolled through or a setting selected.

In this display, the navigation system can also display direction and distance information.

In addition, safety and warning messages can be displayed in this system, such as "Coolant overheating", "Engine system error" or "Washer fluid level too low". In addition to a safety message, a general warning light (red/yellow) lights up.
