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.

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).

CHECKING THE OIL PRESSURE IN THE AM6 AUTOMATIC GEARBOX
WARNING: Clean the flexible pipe of the tool [1] each time before use; the different
automatic gearbox oils cannot be intermixed.
Fit the tool [1]on the tool [2].
Perform the following operations:
- Raise the vehicle, wheels hanging.
- Apply the parking brake.
- Start the engine.
- Check the oil pressure.
WARNING: Wait for the gearbox oil to reach a temperature between 58°C and 68°C.
Check the level of oil in the gearbox (see corresponding operation).
NOTE:Check the temperature of the oil using the diagnostic tool in parameter measures.
Gear lever position: D.
Engine speed: Idling.
Principal oil pressure: 3.7 to 4.2 bars.

TRANSMISSION
CHECKING THE OIL PRESSURE IN THE AM6 AUTOMATIC GEARBOX
Checking the torque converter.
WARNING: This check has to be of short duration (2 seconds), as it causes a rapid
rise in the temperature of the oil in the automatic gearbox.
Respect the following checking conditions:
- Engine at operating temperature.
- Gear lever in position D.
- Press on the brake pedal.
- Accelerate the engine to the maximum engine speed (see below).
Gear lever position.: D.
Maximum engine speed for ES9A : 2400 ± 50 rpm.
Maximum engine speed for DT17 : 2600 ± 50 rpm.
Diagnosis:
- If the maximum engine speed obtained is lower than the value indicated, the torque
converter is the cause.
- If the maximum engine speed obtained is higher than the value indicated, the automatic
gearbox is the cause (slipping).
Additional operations.
Remove tools [1]and [2].
Refit the screw (2), with a new seal.
Reposition the pipe (1).
Refit the air filter housing.

AIR
CONDITIONING
SPECIAL FEATURES: AIR CONDITIONING SYSTEM (R 134.a)
Compressor lubricant
ESSENTIAL: The compressor lubricant is extremely hygroscopic; always use FRESH oil.
Checking the compressor oil level
There are three specific cases:
- 1)Repairs to a system without leaks.
- 2)Slow leak.
- 3)Fast leak.
1) Repairing a system without leaks.
a) - Using draining/recovery equipment not fitted with an oil decanter.
- Drain the system as slowly as possible via the LOW PRESSUREvalve, so as not to lose any oil.
- No more oil should be added when filling the system with R 134.afluid.
b) - Using draining/filling equipment fitted with an oil decanter.
- Drain the R 134.afluid from the system in accordance with the instructions in the equipment handbook.
- Measure the amount of oil recovered.
- Add the same amount of NEWoil when filling the system with R 134.afluid.
c) - Replacing a compressor.
- Remove the old compressor, drain it and measure the oil quantity.
- Drain the new compressor (supplied full), so that the same amount of NEWoil is left in the compressor as was in the old compressor.
- No more oil should be added when filling the system with R 134.afluid.

CONDITIONING
SPECIAL FEATURES: AIR CONDITIONING SYSTEM (R 134.a)
Checking the compressor oil level (continued)
2) Slow leak.
Slow leaks do not lead to oil loss, therefore the same procedure should be followed as if there was no leak at all.
3) Fast leak.
This type of leak causes both oil loss as well as allowing air to enter the system.
It is therefore necessary to:
- Replace the dryer.
- Drain as much oil as possible (when replacing the faulty component).
Either before or during filling of the system with R 134.afluid, introduce 80 ccof NEWoil into the system.
If changing one of the following components, add as below:
- A drying bottle : 15 ccof compressor oil.
- A condenser or an evaporator : 20 cc of compressor oil.
- A high pressure or low pressure pipe : 5 ccof compressor oil.
- A drying cartridge : 15 ccof compressor oil.
