Description Display range 0 to 255 km/h. At vehicle standstill 0 km/h is displayed. Note: In the measured value block a measured value is only displayed when there is no static fault memory entry relating to the speed sensor.

Unit km/h

Possible readout on tester: pressed, 0 and invalid.

If one of these switches is pressed, the tester indicates pressed. If unpressed, the readout is 0.

These data are required to calculate for the ABS/ESP control unit -J104.

Display range 0.0 to 255:59 h; standing time of the vehicle after ignition-off until ignition on. If no message from dash panel insert, text: ERROR; error status Stand time; Text : Invalid. The standing time signal is transmitted by the dash panel insert to control unit -J104. It is required to calculate the brake cooling time. Possible readout Off or On; if Off OK I.e. the EDL system is ready; if On not OK I.e. the EDL system is shut off due to overheating. Possible readout in degrees, min. -720° max. +720°, when front wheels set straightahead max. tolerance +/-5°. Readout in degrees per second: Specification when vehicle stopped= +/- 4,0 °/s Preconditions The vehicle must be standing level in direction of travel.
