TACHOMETRIC INDEX PROGRAMMING
NOTESSpecial notes: ABS warning light flashing at 8 Hz out of fault finding mode.
The Bosch 8.0 ESP computer transmits the vehicle speed signal to all areas where this signal is needed
(instrument panel, engine management, etc.).
This vehicle speed signal replaces the one supplied by the speed sensor located on the gearbox. The ESP
computer calculates the vehicle speed from the wheel speed and the tyre circumference.
Note:
The vehicle speed is conveyed by wire (track 33) to the xenon bulbs, radio and electric sunroof, and by the
multiplex network to the other computers.
The tyre circumference must be programmed into the memory of a new computer. This consists of
entering an X index using the diagnostic tool and the command VP007 Tachometric index.
Once the index has been entered using command VP007 Tachometric index, clear the computer fault memory
and then switch off the ignition. Use parameter PR030 Tachometric index to check that the index entered is being
used correctly by the system.
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.
