ABS BOSCH 8.1
Vdiag No.: 18
On this vehicle, the main functions of the ABS are as follows:
● electronic distribution of braking between front and rear by controlling skidding of the rear wheels,
● keeping the wheels from locking by controlling skidding of the four wheels.
The ABS prevents the wheels from locking when braking. This function allows the vehicle to be steered under
braking and ensures vehicle stability under braking.
EBD (electronic braking distribution):
The electronic braking distribution unit optimises the brakeforce distribution between the front and rear axles. This
function ensures vehicle stability under braking.

PRESENTTACHOMETRIC INDEX PROGRAMMING
NOTESNone.
The ABS BOSCH 8.1 computer with "tachometric function" must have an index value in order to calculate the
vehicle speed from the speed at which the tyres turn.
Use command VP007 Tachometric index and check that it has been taken into account using parameter PR030
Tachometric index.
IMPORTANT:
The vehicle speed information is not delivered to the other computers by the ABS computer.
The vehicle speed signal is delivered by a speed sensor located on the gearbox, which informs the
computers (instrument panel, engine management, etc.).
If the fault is still present, contact the Techline.
