Description of the scrolling values (lamps)

Warning lamp seat belts, value
Indicates whether the lamp is on or off according to the control module.

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

Brake system warning lamp, value
The ABS control module lights or extinguishes the lamp via the control area network. The lamp may assume the value on or off.

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

Lamp low oil pressure, value
The oil pressure signal can be read off. The signal comes from the engine control module (ECM). One can read off whether the low oil pressure lamp should be on or off.

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

Indicator lamp fog lamp rear, value
Indicates whether the lamp is on or off according to the control module.

Malfunction indicator lamp (MIL), value
Indicates whether the lamp is on or off according to the control module.

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

Traction control warning lamp, value
The Brake Control Module (BCM) transmits the lamp signal to the driver information module (DIM) via the Control area network (CAN). Indicates whether the lamp is on or off according to the Driver Information Module (DIM).

Diesel preheating lamp
Indicates whether the lamp is on or off according to the control module.

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.

Lamp low fuel level, 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 (REM). The value displays between 0 and 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 is between 0 and 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 Brake Control Module (BCM) or the transmission control module (TCM) via the Control area network (CAN).

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

Parking brake, value
The sensor is directly connected to the driver information module (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 status, value
The Driver Information Module (DIM) informs the Supplemental Restraint System Module (SRS) if the indicator lamp is working or is defective.

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

Description of the customer parameters in the driver information module (DIM)

Total mileage, value
Measurement range 0-999999 km, 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 the control module has been replaced.

Distance conditions for service, value
Indicates the mileage required to display the service indicator message. The available values for metric calibrated instruments are 5000, 7500, 10000, 12000, 15000 or 20000 km. The available values for imperial calibrated instruments are 2500, 5000, 6000, 7500, 10000 or 12500 miles.

Time conditions for service, value
Indicates the time required to display the service indication message. The values set are 6, 12, 18 or 24 months.

Engine run time conditions for service, value
Indicates the time the engine must have been running before the service indication message will be displayed. 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. The temperature display can be selected between Celsius or Fahrenheit.

Unit trip computer, 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 message, the parameter is reprogrammed by copying the global time in the central electronic module (CEM) to the driver information module (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. Resets when service reminder message is reset.

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.

Parking brake warning
Setting the sound signal for the parking brake warning. Parking brake warning can be on or off. The default position is on.
