Taximeter, task - GF54.61-P-4107-01S

The tasks of the taximeter control module (A67n1)  are as follows:

• Switch the roof sign lamp on/off automatically or via a discrete switch (with status display in interior mirror)
• Store the journey information in journey memory (storage capacity: information on approx. 800 journeys)
• Record the distance covered via the integrated odometer
• Receipt of the DCF time signal via the time signal receiver in the taximeter
• Read out the journey information via a serial data interface (HALE-CEY system, special equipment)
• Connect a printer via an RS485 interface

System test mode (also refer to Taxi Owner's Manual) 

The following tests/checks can be carried out in the taximeter's system test mode:

• DCF time signal test (display: "dCF")
• Vehicle speed test (display: "SPd") or
• Check the trackage with distance pulse display
• Display brightness test
• Temperature test
• Display test
• Seat contact test
• Check calibration checksums
• Check system time with date and year

The wheel speed signal used by the taximeter control module originates from the traction systems control module (N47). This control module reads in the sensor signal from the left front vehicle speed sensor (L6/1) for this.

If the ambient temperature at the taximeter rises above 85°C, the display is switched off automatically. If the temperature then drops below the limit value again, the display is switched on automatically.

Taximeter automatic shutoff 

The following options can be programmed with the Star diagnosis tool:

Taximeter automatic shutoff when ignition/starter key is in position "0":

• YES/NO
• YES after a time delay of up to 255 minutes
