Engines : 6FZ - RFN - RHZ - XFX - 4HX
Procedure prior to carrying out repairs (continued)
When the ECU detects an erroneous or non-existent value
on input or output :
- It writes the fault in memory.
- For each associated context, it writes the context of the oldest fault
in memory.
- It initiates a back-up mode strategy.
There are two types of back-up modes :
- The ECU makes replacement values available (relating to comfort,
gear selection quality, loss of functions).
- Access to emergency programme (only 3rd ratio and reverse are
available)
NOTE : 4 HP 20 : A snatching may be felt when changing :P/R - N/R - N/D.Reading the fault codes.
Read the fault codes.
No fault codes present :
Carry out a measure of parameters.
Anomalies present :
- YES : Carry out the necessary repairs.
- NO : Read the fault codes – engine ECU.
- Carry out a road test.
Following an initialisation of the ECU, for a certain period of time there
may be an inconsistent gear selection quality(while ECU parameters
are adapted to the gearbox).
To achieve a consistent standard, it is necessary to carry out a road test
taking in frequent gear changes (auto-adaptive laws).

Downloading. ( AL 4 and 4 HP 20 )
Updating the gearbox ECU by downloading :
- Follow the procedure using the diagnostic equipment.
The operation of downloading is used to update the automatic gearbox ECU or to adapt it to evolutions of the engine ECU.
After downloading, carry out the following :
- Note down the value in the oil usage counter present in the automatic gearbox ECU.
- Delete the fault codes.
- Again note down the value in the oil usage counter and compare it with the value previously read.
- Pedal initialisation (AL 4)
- Configuration (if needed) (AL 4)Following the diagnostic tool procedure.
- A reinitialisation of the autoadaptives (AL4 - 4 HP 20).
- A road test (AL 4 - 4 HP 20).
IMPERATIVE : Every update of the automatic gearbox ECU must
be accompanied by an update of the engine ECU.

Downloading (AL 4 only).
ECU downloading procedure :
- Follow the diagnostic tooling procedure.
A new ECU or downloaded update is always configured
with the following options :
- SHIFT LOCK gear selection lever position.
- OBD outlet(emission standard L4).
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.Pedal initialisation. (AL 4 only).
A pedal initialisation must be carried out in the following cases :
- Replacement of the automatic gearbox ECU.
- Replacement of the automatic gearbox.
- Downloading of the ECU configuration.
- 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 lockis 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».
- 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 shutter.
Unlock the «shift lock» (4)using a screwdriver.
Using the selection lever, disengage from position «P».

Selection control.
The gear selection control has 5 positions.
The selection lever is guided by the shape of the stepped gate and by a retaining spring which holds it
towards the left.
The gear selection control is equipped with the «shift lock», so you have to switch on the ignition and
apply the brake pedal to unlock the selection lever from the park position.
Selection (P): Park(locking and immobilisation of the vehicle).
Selection (R): Reverse gear.
Selection (N) : Neutral.
Selection (D): Drive (Use of the four gears in their autoadaptive automatic function).
Selection (M) : Manual (M + M -)allowing the driver to select gears by pulling and pushing the gear lever.
In position M, selection is by an electronic sensor located close to the gear lever.
The variation of flux necessary to the movement of the sensor cells is obtained by a magnet located on
the lever itself. This enables the change of status.

Selection control (continued).
In positionM, selection is by an electronic sensor located close to the gear lever.
The variation of flux necessary to the movement of the sensor cells is obtained by a magnet located on
the lever itself. This enables the change of status. The information is transmitted to the gearbox ECU.
Two switches placed on the gear control gate permit the driver to choose one of the following three
driving programmes:
- Normal :The normal programme operates in the absence of the other two (Eco law, autoadaptative mode).
- Sport :Permits a more dynamic, sporty performance.
- Snow :Facilitates starting and adhesion on slippery surfaces.
To return to the normal programme, press a second time on the sport switch or snow switch.
Only when the selector is in position(P)or (N)can the engine be started.
(1)Control linkage with ball-joint.
(2)Automatic adjustment(Push-button pressed in to lock the control adjustment, springs out for the
adjustment to be made) «c» Push-button locking clip in pressed-in position.
(3) Cable sleeve stop.
The automatic gearbox is controlled by cable.
