PRESENTTACHOMETRIC INDEX PROGRAMMING1. DEF: tachometric index not programmed
NOTESNone.
The ESP computer with the tachometric function supplies the vehicle speed signal to all areas where this
information 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.
The tyre circumference must be programmed into the memory of a new computer. This consists
of entering an X index using command VP007 Tachometric index on the diagnostic tool.
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.
