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.

NOTESSpecial notes:
The injection does not always store these transient faults as quickly as the ESP
system.
If no fault is stored in the injection computer, start the engine; if there is no fault present,
contact the Techline.
Once the fault in the injection system has been repaired, clear the ESP computer
fault memory.
Priority in the event of a number of faults:
Deal with fault DF152 Multiplex network first if it is present or stored.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present when the engine is started.
Check the injection computer (see13B, Diesel injection or 17B, Petrol injection)usingthe diagnostic tool.

STOREDNO UCH MULTIPLEX SIGNAL
NOTESSpecial notes:
Even though this is stored in the computer, this fault does not cause the warning lights
to come on or a fault message, because the ESP system is not faulty.
Perform fault finding on the UCH (Passenger compartment connection unit) using
the diagnostic tool.
Note:
After repairing the fault in the UCH (Passenger compartment connection unit),
clear the fault memory in the ESP system.
Priority in the event of a number of faults:
Deal with fault DF152 Multiplex network first if it is present or stored.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present when the engine is started.
Check the UCH (Passenger compartment connection unit) using the diagnostic tool (see 87B, Passenger

NOTESSpecial notes:
If the fault appears while the vehicle is being driven on a steep gradient, during a very
tight turn or while the vehicle is being transported on a lorry, train, boat etc., with the
engine running, clear the fault and test drive, if possible, to check that the fault does
not return.
Conditions for applying fault finding procedures to stored faults:
The fault is declared present after a road test.
Check that component 1175 is fitted and attached correctly (the arrow indicating the front of the vehicle).
Check the conformity of the tyres (see MR 411, Mechanical, 35A, Wheels and tyres, Tyres: Identification
and Tyre pressure, Identification).
Check the axle assembly geometry (see MR 411, Mechanical, Chassis, Front axle adjustment).
Calibrate component 583 using command VP003 Steering wheel angle sensor (see Configurations
and programming).
Clear the ESP sensor offsets using command RZ011 Sensor offset.
Re-establish dialogue with the ABS/ESP computer, and if no other fault is to be dealt with, clear the computer fault
memory.
Carry out a road test.
If the fault is still present, contact the Techline.
