SPEEDOMETERALL TYPES
An E.E.C. decree of 25 June 1976, regulates the speed displayed by the speedmeter in relation to the actual speed travelled.
This decree stipulates:
The speed indicated by a speedometer must never be lower than the actual vehicle speed.
Between the speed displayed «SD»and the speed travelled «ST», there must always be the following relationship:
ST < SD < 1.10 ST + 4 Kph
Example: For an actual speed of 100 Kphthe speed displayed by the speedometer may be between 100and 114 Kph.
The speed indicated by the speedometer may be influenced by:
The speedometer.
The tyres fitted to the vehicle.
The final drive ratio.
The speedometer drive ratio.
Any of these components can be checked without removing them from the vehicle
(see information note N° 78-85 TT of 19 October 1978).NOTE:Before replacing the speedometer, check the conformity of the following points:
The tyres fitted to the vehicle.
The gearbox final drive ratio.
The speedometer drive ratio.

Operations on electrical components.Do not disconnect:
The battery when the engine is running.
The ECU with the ignition switched on.
The clutch and gearbox actuators with the ignition switched on.
When carrying out electrical checks: The battery must be correctly charged.
Never use a voltage source higher than 16V.
Never use a lamp to supply an actuator directly.
Before disconnecting connector, check: The condition of the various contacts (for deformation, corrosion, etc).
The presence and the status of the mechanical unlocking.
Driving the vehicle.
IMPERATIVE:
Never move the vehicle with the ignition switched off.
Never push the vehicle to attempt to start it
(impossible with a piloted
manual gearbox).
Towing.
Conditions for towing.
It is necessary to lift the front of the vehicle to tow it, after having
positioned the gear lever in neutral. If there is a gearbox fault or
malfunction, the vehicle can remain immobilised depending on theseriousness of the fault.
If a gear is engaged,the conditions for immobilisation of the
vehicle are:
Combustion engine stopped (the engine should not be started).
The clutch is open (clutched).
In these conditions are met, you can lift the front of the vehicle to tow it.
If it should not be possibe to lift the front of the vehicle, there are
ways to unblock it:
Engage «N», using a diagnostic tool.
Engage «N», without using a diagnostic tool.

If a gearbox malfunction occurs, there are two possible
configurations depending on the seriousness of the fault:
Gearbox in backup mode with a replacement programme of
(the
fault values are taken in substitution).
Gearbox in backup mode with an emergency programme (3rd
hydraulic).WARNING:In the emergency programme, an impact is felt
when changing P/R, N/R and N/D.
Réception client.
Discuss with the customer, to find out all the malfunction symptoms.Oil quality Oil level.
Oil quality.
If the gearbox has suffered a serious fault resulting in a malfunction
or the destruction of a clutch, the oil will overheat and become
contaminated with impurities: the oil is said to be
«burnt».
This is characterised by a black colour and the presence of an
unpleasant smell.
ESSENTIAL: The gearbox must be replaced.
Oil level (see corresponding operation).
An excessive oil level can result in the following consequences:
Excessive heating of the oil.
Oil leaks.
An insufficent level causes the destruction of the gearbox.
Top up the level of oil in the gearbox (if necessary).
Check using a diagnostic tool.
Read the fault codes
(engine and gearbox).
Absence of fault codes.Carry out parameter measures, actuator tests and a road test.
Presence of fault codes.Carry out the necessary repairs.
Delete the fault codes.
Carry out a road test to check the repair and, if need be, modify the
gearbox ECU parameters
(this is essential after an initialisation
of the ECU).

Precautions to be taken.
Towing.
The front of the vehicle must be raised in order to be towed.
If the front of the vehicle cannot be raised:
IMPERATIVE: Put gear lever in position «N».
Do not add any oil.
Do not exceed
30 mphover a distance of 30 milesof maximum.
Driving.
Never drive with the ignition switched off.
Never push the vehicle to try to start it
(impossible with an automatic gearbox).
NOTE:The automatic gearbox is only lubricated when the engine is
running.
Repairs on electrical components.
Do not disconnect:
The battery when the engine is running.
The ECU when the ignition is switched on.
Before reconnecting a switch,check: The condition of the various contacts (for deformation, corrosion etc).
The presence and condition of the mechanical locking.
When performing electrical checks: The battery should be correctly charged.
Never use a voltage source higher than 16V.
Never use a test lamp.

Downloading.
Updating the gearbox ECU by downloading:
Follow the procedure using the diagnostic tool.
The downloading operation enables the automatic gearbox to be updated, or adapted to an evolution of the engine ECU.
Before commencing the downloading, take the value of the oil usage counter present in the automatic gearbox ECU.
After the downloading operation, carry out the following: A clearing of faults.
A pedal initialisation.
A reinitialisation of the autoadaptives.
A programming
(if necessary).
A writing of the value of the oil usage counter previously read.
A road test.
ESSENTIAL: Every update of the automatic gearbox ECU should be accompanied by an update of the engine ECU.
