ABS warning lamp, value
Indicates whether the lamp is on or off according to the control module.

Anti-spin warning lamp, value
The ABS control module transmits the lamp signal to the combined instrument panel via the Control area network (CAN). Indicates whether the lamp is on or off according to the control module (DIM).

Service reminder indicator (SRI), value
The lamp flashes if the programmable service parameters are not programmed for some reasons or if the signals are not updated on the Control area network (CAN). The lamp can be on, off or flashing.

Trailer warning lamp, value
Indicates whether the lamp is on or off according to the control module.

General orange warning lamp, value
Indicates whether the lamp is on or off according to the control module.

General red warning lamp, value
Indicates whether the lamp is on or off according to the control module.

High beam, value
Indicates whether the lamp is on or off according to the control module.

Low fuel level warning lamp, value
Indicates whether the lamp is on or off according to the control module.

Description of the scrolling values (other signals)

Fuel level, value
Signal from the two fuel level sensors in the rear electronic module. The value displays between 0 - 80 liters depending on the amount of fuel in the tank.

Engine coolant temperature, value
An engine coolant temperature (ECT) display. The signal comes from the engine control module (ECM) and the temperature is displayed in Celsius.

Engine speed (RPM), value
An engine speed (RPM) display. The signal lies between 0 - 8000 rpm and comes from the engine control module (ECM).

Vehicle speed, value
The vehicle speed can be read off. The signal comes from the ABS control module or the transmission control module (TCM) via the Control area network (CAN).

Brake fluid level, value
The sensor is directly connected to the combined instrument panel (DIM). Indicates whether the control module interprets the signal as low or high level.

Parking brake, value
The sensor is directly connected to the combined instrument panel (DIM). Indicates whether the control module interprets the signal as activated or not activated. With the parking brake applied the sensor is activated.

The SRS indicator lamp, value
The combined instrument panel informs the SRS if the indicator lamp functions or is defective.

Cruise control, value
Indicates whether the cruise control status is on or off.

Description of the customer parameters in the combined instrument panel (driver information module)

Total mileage, value
Measurement range 0-999999 km or 0-999999 miles. The parameter can only be programmed once before the read off mileage exceeds 500 km or 310 miles. Programmed by the central electronic module (CEM) after replacing the control module.

Distance conditions for service, value
Indicates the distance driven required to light the service reminder indicator (SRI). The value set for metric calibrated instruments are 5000, 7500, 10000, 12000, 15000 or 20000 km. The value set for imperial calibrated instruments are 2500, 5000, 6000, 7500, 10000 or 12500 miles.

Time conditions for service, value
Indicates the time period required to light the service reminder indicator (SRI). The value set is 6, 12, 18 or 24 months.

Engine run time conditions for service, value
Indicates the engine run period required to light the service reminder indicator (SRI). The value set is 500, 750 or 1000 hours.

Displaying zeroes, value
Setting the instrument panel to display or not display the zeroes.

Temperature unit, value
The temperature unit of measurement can be selected. Temperature display can be selected between Celsius or Fahrenheit.

Trip computer unit, value
Setting the trip computer (applies only to cars with trip computer). It is possible to select liters, Imperial gallons or US gallons.

Clock position, value
12- or 24- hour display.

Mileage at service, value
Reading off the mileage at service. The parameter can be programmed between 0 -999999 km or miles. When resetting the service reminder indicator (SRI) the parameter is reprogrammed by copying the mileage.

Caution! Mileage at service should be used with total mileage to determine whether a service is due.

Time at service, value
Reading off global time at service. The parameter can be between 0 -163 months (13.6 years). When resetting the service reminder indicator (SRI) the parameter is reprogrammed by copying the global time in the central electronic module (CEM) to the combined instrument panel (DIM).

Caution! Time at service and global time should be used with time conditions to determine whether a service is due.

Engine hours since service, value
Parameter read off. Indicates how many hours the engine has run since the last service. The parameter can be between 0 -65536 hours. Reset when resetting the Service reminder indicator (SRI).

Caution! Engine time since service should be used with engine hours to service to determine whether a service is due.

Global time, value
Reading off the clock in the central electronic module (CEM). The parameter can be between 0 -163 months (13.6 years).

Caution! Time at service and global time should be used with time conditions to determine whether a service is due.

Description of component / function activation

Lamps and displays
The combined instrument panel lamps flash and the gauges sweep from minimum to maximum for 4 seconds.

Extinguish the service reminder indicator (SRI)
The service reminder indicator (SRI) is extinguished and global time in the central electronic module is copied to the combined instrument panel (DIM). The engine time since service is reset and the total mileage is copied to mileage at service.
