RECOMMENDATIONS - PRECAUTIONS (AL 4 and 4 HP 20 AUTOMATIC GEARBOXES)
Engines : 6FZ - RFN - RHZ - XFX - 4HX
CLUTCH
GEARBOX
DRIVESHAFTS
ECU : Downloading, Configuration, Initialisation (Pedal).
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.

Reminder : All repairs on an aircon circuit require the aircon circuit to be drained.
After carrying out the dismantling operations necessary to gain access to the condenser, proceed to clean
the area of the skirt (8) of the reservoir(6)using a cloth, then replace the dryer reservoir (6).
Removing the plastic bracket holding the reservoir (6) :
- Remove the screw (3)(Torx 20), from the bracket assembly/plastic counter-bracket (4)and (5).
- Remove the counter-bracket (5). (Rotate it round the hinge in a clockwise direction).
- Disengage the bracket from the harness(1)(Rotate it round the reservoir (6)anti-clockwise).
- Remove the bracket(5) from the reservoir body (6).
Unscrewing the reservoir (6).
- Unscrew the reservoir(6)using the tool[2].
