TACHOMETRIC INDEX PROGRAMMING
NOTESSpecial notes:
ABS warning light flashing at 8 Hz outside fault finding conditions.
The BOSCH ABS 8.0 computer supplies the vehicle speed signal to all vehicle systems that use this information
(instrument panel, engine management, etc.).
This vehicle speed signal replaces the one supplied by the speed sensor located on the gearbox. The ABS
computer calculates the vehicle speed from the speed of the wheels and the circumference of the tyres fitted on
the vehicle.
Note:
The vehicle speed is sent by wire (track 23) to the xenon bulb computer, radio and electric sunroof, and via the
multiplex network to the other computers.
The tyre circumference must be programmed into the memory of a new computer. This consists of
entering a number X using the VP007 "Tachometric index" command on the diagnostic tool.
Once the index has been entered using the VP007 command, clear the computer fault memory and then switch
off the ignition.
Use the parameter PR030 to check that the index entered has been stored correctly.
If the fault is still present, contact the Techline.
AFTER REPAIRClear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool.

Visually inspect the condition of the target and sensor (for dirt, metallic contamination, bearing grease, etc.), and
clean using compressed air if necessary.
If there is a lot of grease on the target, contact the Techline.
Check the quality of the mounting of the wheel speed sensor (correct clipping without excessive play).
Check the sensor/target air gap over one wheel revolution: 0.1 mm < front wheel air gap < 1.2 mm.
Check the conformity of the target (condition, number of teeth = 48) using the specific command SC001 Check
target teeth.
If the checks are correct:
–the computer fault memory has been cleared,
–exit fault finding mode, switch off the ignition and carry out a road test.
Replace the instrumented bearing if the fault recurs.
AFTER REPAIRClear the computer fault memory.

computer connector.
If the brake lights do not operate:
–Check the condition and fitting of the brake light switch and brake lights fuse.
–Remove the brake light switch and check that it is operating correctly:
