GEARBOX
TRANSMISSION
AM6 GEARBOX CONTROLSThe gear selector is guided by the shape of the stepped gate and by a retaining spring which
pulls it to the left hand side.
The gear control has 5 positions:
- Position "P": parking (locking and immobilisation of the vehicle).
- Position "R": reverse gear.
- Position "N": neutral.
- Position "D": drive (for use of the 6 gearsin autoadaptive automatic operation).
- Position "M": manual (this position allows the driver to select his gears in one-touch mode by
pulling "M -"or pushing "M +"on the gear selector).
NOTE:Only positions "P"or "N"authorise starting of the engine.
In position "M", the selection is enabled by an electronic sensor located close to the gear
selector:
- The variation of flux necessary to affect the sensor cells is obtained by a magnet on the lever
opposite the cells, provoking the changes of status.
- The information on this is transmitted to the gearbox ECU.

AM6 GEARBOX CONTROLS: «SHIFT LOCK» FUNCTIONIMPERATIVE: Respect the safety and cleanliness requirements, with reference to the brochure:
«Recommendations-Precautions».
The «shift lock»is a system that locks the gear selection lever in position «P».
Unlocking the «SHIFT LOCK»(normal operation).
Switch on the ignition.
Press the brake pedal and keep it pressed.
Move the gear selection lever out of position «P».
Unlocking the «SHIFT LOCK» (with an operating fault).
Should it be impossible to unlock the «shift lock»with the «Normal operation»method.
The fault may originate from one of the following components:
- «Shift lock».
- Gear lever position switch.
- Automatic gearbox ECU.
- Electrical harness.
- Battery voltage.
Operations to be performed.
Unclip the cover (1).
Unlock the «shift lock»by pressing at "a"with the aid of a screwdriver (screwdriver with a minimum length of
150 mm).
Move the gear selection lever out of position "P".

PROCEDURE FOR INITIALISATION OF THE AUTOMATIC GEARBOX ECU
NOTE:For all these operations, follow the procedure in the diagnostic tool.
Replacement of the automatic gearbox without replacement of the ECU.
Carry out the following operations:
- Initialisation of the neutral position of the gear selection lever position sensor.
- Initialisation of the adaptation of the oil pressure regulators and electrovalves.
- Initialisation of the autoadaptatives.
- Resetting the oil usage counter to zero.
Replacement of the automatic gearbox ECU.
Carry out the following operations:
- Read the value of the gearbox oil usage counter from the old ECU.
- Write the value of the oil usage counter into the new ECU.
- Initialisation of the neutral position of the gear selection lever position sensor.
- Initialisation of the adaptation of the oil pressure regulators and electrovalves.
- Initialisation of the autoadaptatives.

GEARBOX
TRANSMISSION
PROCEDURE FOR INITIALISATION OF THE AUTOMATIC GEARBOX ECU
Replacement of the automatic gearbox and of the automatic gearbox ECU.
Carry out the following operations:
- Initialisation of the autoadaptatives.
- Resetting the oil usage counter to zero.
- Initialisation of the adaptation of the oil pressure regulators and electrovalves.
Draining of the automatic gearbox oil.
Carry out the following operations:
- Initialisation of the adaptation of the oil pressure regulators and electrovalves.
- Resetting the oil usage counter to zero.
NOTE:If downloading the automatic gearbox ECU, there is no specific operation, follow the procedure in the diagnostic tool.
IMPERATIVE: For a certain time, having carried out an ECU initialisation procedure, one may obtain gear changing quality that is more
or less good (adaptation of the ECU parameters to the gearbox). To improve the quality, it is necessary to perform a road test with
frequent changing through the gears (auto-adaptive laws).

WARNING: Each time a tyre is replaced, it is necessary to replace the valve (4).
WARNING: Each time a wheel rim is replaced, it is necessary to replace the
seal (8).
WARNING: Each time a transmitter module is changed, it is necessary to have
the replacement recognised by the deflation detection ECU, using a diagnostic
tool.

Composition of the Built-in Hydro-electronic Interface:
- An electric motor.
- A pump with 5 pistons.
- 4electrovalves.
- 2non-return valves.
- A pressure limiter.
- An anti-pulse accumulator.
- A filter.
- The suspension ECU.
Features of variable damping suspension.
Variable damping suspension ECU (CSS).
The ECU (CSS)is located in the engine compartment, in the ECU tray.
The ECU (CSS)manages the different damping laws, as a function of the information delivered
by the following components:
- The 4wheel travel sensors.
- The 2suspension pressure sensors.
- The speed of the vehicle.
- The speed of rotation of the steering wheel.
The suspension ECU (CSS)pilots the following components:
- The 4variable damping suspension actuators.
- The Built-in Hydro-electronic Interface (BHI).

(9)Front RH wheel travel sensor
The wheel travel sensor defines the angular position of the suspension lower arm.
Identification of the sensors:
- Front RH wheel travel sensor: Yellow.
- Front LH wheel travel sensor: Red.
- Rear RH wheel travel sensor: Green.
- Rear LH wheel travel sensor: Blue.
IMPERATIVE: Before operating on a wheel travel sensor, uncouple its rod so as not to
go past the maximum angular travel (see corresponding operation).
The suspension pressure sensors (7)informs the suspension ECU (CSS)of the pressure in
the hydraulic high pressure pipes of the front suspension.
The sensor (13)informs the suspension ECU (CSS)of the pressure in the hydraulic high
pressure pipes of the rear suspension.
