RECOMMENDATIONS - PRECAUTIONS (AL 4 AUTOMATIC GEARBOX)

Engine : KFV

PRECAUTIONS TO BE TAKEN

Towing

REMOVING - REFITTING (Automatic gearbox).

The front of the vehicle must be raised in order to be towed.

If the front of the vehicle cannot be raised

WARNING : Never place the gearbox on its lower casing

(risk of deforming the tray and damaging the hydraulic valve block).

Never use the connections as handles for raising, turning, holding or

pushing the gearbox.

IMPERATIVE : - Put gear lever in position «N»..

- Do not add any oil.

- Do not exceed 50 kph over a distance of 50 km.

Driving.

ESSENTIAL :

Never drive with the ignition switched off.

Never push the vehicle to try to start it;

(impossible with an automatic gearbox).

- Fit the converter retaining peg while the gearbox is removed.

- Fit the centring peg to locate the gearbox on the engine:

(remove the converter retaining peg just before locating)

Lubrication

The automatic gearbox is only lubricated when the engine is running.

WARNING : With the safety programme selected, a snatching can be

felt when changing from "P" ꢀ "R" or "N" ꢀ "R".

Engine : KFV

Gearbox only

PROCEDURE BEFORE REPAIRS

Oil level AL 4 (prior conditions).

- Vehicle in horizontal position.

- Check gearbox is not in back-up mode.

- Remove the oil filler plug (3).

- Add 0.5 litres extra oil into the gearbox.

- Foot on the brake, change through all the gears.

- Selection lever in position "P".

- Engine running, at idle.

- Oil temperature : 60°C (+8°C; -2°C), measured with the aid of a diagnostic tool.

- Remove the oil level plug (3).

- Thread of oil then "drip-drip": refit plug (3). Tighten 2.4 m.daN.

- "Drip-drip" or nothing : refit the plug (3).

- Stop the engine.

- Add 0.5 litres extra oil into the gearbox.

- Repeat the oil level procedure.

NOTE : The level is correct at the moment the thread of oil becomes drip-drip.

- Refit the oil filler plug (3). Tighten to 2.4 m.daN.

Initialise the oil usage counter (open the diagnostic tool procedure).

NOTE : The dimension X : TU engines = 81 mm

Read the fault codes.

- It writes the fault in memory.

Absence of fault codes:

- For each associated context, it writes the context of the oldest

Carry out a measure of parameters.

fault

in memory.

Presence of anomalies:

- It initiates a back-up mode strategy

- YES : Carry out the necessary repairs.

- NO : Read the fault codes – engine ECU

There are two types of back-up modes :

- Carry out a road test.

- The ECU makes replacement values available (relating to comfort,

gear selection quality, loss of functions).

Following an initialisation of the ECU, for a certain period of time there

may be an inconsistent gear selection quality (while ECU parameters

are adapting to the gearbox.

To achieve a consistent standard, it will be necessary to carry out a

road test taking in frequent gear changes (auto-adaptive laws)

- Access to emergency programme (only 3rd gear and reverse are

available)

RECOMMENDATIONS - PRECAUTIONS (AL 4 AUTOMATIC GEARBOX)

Engine : KFV

ECU : 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.

An initialisation of the auto-adaptives.

A recording 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.

Updating the value of the oil usage counter.

Using PROXIA

Using LEXIA or ELIT.

Access to reading and recording of the oil counter is via the menu :

«Oil counter ».

Adjustment of the oil counter value is done by entering directly the

5 figures of the oil counter.

Access to reading and recording of the oil counter is via the menu :

«Configuration (integrated circuit button) / Oil counter ».

Adjustment of the oil counter value is done in incremental steps of

2750 units.

ECU : Downloading, Configuration, Initialisation (pedal) (continued)

Downloading.

Pedal initialisation.

ECU downloading procedure :

- Follow the diagnostic tooling procedure.

A pedal initialisation must be carried out in the following cases :

- Replacement of the automatic gearbox ECU.

- Replacement of the automatic gearbox.

A new ECU or downloaded update is always configured

with the following options :

- SHIFT LOCK gear selection lever position.

- OBD outlet (emission standard L4).

- Downloading of the ECU configuration.

If the ECU is to be fitted to a vehicle without one or both

of these options:

- Carry out a configuration which inhibits the diagnosis of the

option(s) concerned.

- Adjustment or replacement of the accelerator cable.

- Replacement of the throttle potentiometer.

IMPERATIVE : For a certain period of time, while the ECU parameters are adapted to the gearbox, there may be an inconsistent gear

selection quality. To achieve a consistent standard, it will be necessary to carry out a road test taking in frequent gear changes

(auto-adaptive laws).

SHIFT LOCK

The shift lock is a system which locks the gear selection lever in the park position «P».

Unlocking the «shift lock» (normal operation).

Switch on the ignition.

Apply the brake pedal and keep it pressed.

Using the selection lever, disengage from position «P».

Unlocking the «shift lock» (with a fault).

NOTE : It is impossible to unlock the «shift lock» with the « normal operation» method.

The causes of the fault may arise from the following components :

- «Shift lock».

C5FP0ETC

- Gear lever position switch.

- Automatic gearbox ECU.

- Electrical harnesses.

- Battery voltage.

Remove :

- The gear lever knob (1) by pulling upwards.

- The cover (2) (unclip).

- The top of the central console (3).

Unlock the «shift lock» (4) with aid of a screwdriver.
