GENERAL
ENGINE OIL CONSUMPTION
I-Oil consumption depends on:
- The engine type.
- How run-in or worn it is.
- The type of oil used.
- The driving conditions.
II -An engine can be considered RUN-INafter:
- 3 000 miles (5 000 km)for a PETROLengine.
- 6 000 miles (10 000 km)for a DIESELengine.
III - MAXIMUM PERMISSIBLEoil consumption for a RUN-INengine.
- 0.5 litresper 600 miles (1 000 km)for a PETROLengine.
- 1 litreper 600 miles (1 000 km)for a DIESELengine.
DO NOT INTERVENE BELOW THESE VALUES.
IV - OIL LEVEL:The level should NEVERbe above the MAX.mark on the dipstick after changing or topping up the oil.
- This excess oil will be used up rapidly.
- It will reduce the engine output and adversely affect the operation of the air circuits and gas recycling.

INJECTION
CHECKS: TURBO PRESSURE
Engine: DT17BTED4
Connect:
- The tool [2a]in place of the turbo pressure sensor (1).
- The turbo pressure sensor (1)on the tool [2b].
- Tool [1]on tool [2], at "b".
Connect the diagnostic tool [3]or [4]to the vehicle's diagnostic socket:
- Put the diagnostic tool [3]or [4]in parameter measures.
Start the engine.
Accelerate to 2500 rpm.
Compare the pressure values read on the diagnostic tool and on the pressure gauge [1].
NOTE:If there is a significant difference in pressure, replace the turbo pressure sensor.
Air/air exhanger.
Check the condition of the following components:
- Air inlet pipe.
- Airoutlet pipe.
- Air /air exchanger.
Air flow from the turbochargers.
NOTE: If an air flow fault is memorised by the diagnostic tool, check the air flow from the turbocharger
incriminated.
Connect the diagnostic tool [3]or [4]to the vehicle's diagnostic socket:
- Put the diagnostic tool [3]or [4]in parameter measures.
Start the engine.
Accelerate to 2500 rpm.
Compare the air flows (mg/stroke)from the two turbochargers.

INJECTION
CHECKS: TURBO PRESSURE
Engine: DT17BTED4
Significant difference in pressure between the two turbochargers:
- Stop the engine.
- Remove the air filter with the two flowmeters.
- Mark the flowmeters "d"and "c".
- Remove both flowmeters.
Refit:
- Flowmeter "d"in place of flowmeter "c".
- Flowmeter "c"in place of flowmeter "d".
Start the engine.
Accelerate to 2500 rpm.
Compare the air flows (mg/stroke)from the two turbochargers:
- If the difference in air flow has changed turbochargers, replace the flowmeter that is faulty.
- If the difference in air flow is coming from the same turbocharger, check the condition of the air inlet
and outlet pipes of this turbocharger: replace or repair the parts that are faulty.
- If no anomaly is detected on the air inlet and outlet pipes of the turbocharger: replace the turbocharger.

GEARBOX
TRANSMISSION
PROCEDURE PRIOR TO OPERATIONS: AM6 AUTOMATIC GEARBOX
If a gearbox malfunction occurs, there are two possible configurations
depending on the seriousness of the fault:
- Gearbox in back-up mode with a replacement programme of (the fault
values are taken in substitution).
- Gearbox in back-up mode with an emergency programme (3rd hydraulic).
WARNING: In the emergency programme, an impact is felt when
changing P/R or N/R.
Reception of the customer.
Discuss with the customer, to find out all the malfunction symptoms.
Oil quality.
If the gearbox has suffered a serious fault resulting in a malfunction or
the destruction of a clutch, the oil will overheat and become
contaminated with impurities: the oil is said to be «burnt».
This is characterised by a black colour and the presence of an
unpleasant smell.
ESSENTIAL: The gearbox must be replaced.Oil level.
Preliminary conditions:
- Vehicle horizontal, parking brake off.
- Check that the gearbox is not in back-up mode (using a diagnostic tool).
- The oil temperature should be 60°C (+8, -2)(using a diagnostic tool).
- Press on the brake pedal, change through all the gears.
- Place the gear lever in position P.
With the engine running at idle, without power consumers (aircon,
heating, etc.):
- Remove the oil level plug.
The oil should flow out, then drip-drip.
Refit the oil level plug (the oil level is correct).
The oil does not flow out through the oil level plug (see operation: drain
fill - bleed the gearbox).
Engines: ES9A - DT17BTED4

PRECAUTIONS TO BE TAKEN : AM6 AUTOMATIC GEARBOX
Towing.
The front of the vehicle must be raised in order to be towed.
If the front of the vehicle cannot be raised.
IMPERATIVE:
- Put gear lever in position «N».
- Do not add any oil.
- Do not exceed 70 km/h (45 mph)over a distance of 100 km (60 miles)
maximum.
Driving.
Never drive with the ignition switched off.
NOTE:The automatic gearbox is only lubricated when the engine is
running.
Repairs on electrical components.
Do not disconnect:
- The battery when the engine is running.
- The ECU when the ignition is switched on.
Before reconnecting a switch, check:
- The condition of the various contacts (for deformation, corrosion etc.)
- The presence and condition of the mechanical locking.When performing electrical checks:
- The battery should be correctly charged.
- Never use a voltage source higher than 16V.
- Never use a test lamp.
Repairs on mechanical components.
Never place the gearbox on the ground without protection.
Do not use the unions on the gearbox as handles for moving the
gearbox.
It is imperative
that the converter retaining peg should be in place
when removing the gearbox.
It is imperativeto use the centring pegs to couple the gearbox on the
engine.
Remove the converter retaining peg before coupling the gearbox on
the engine.

GEARBOX
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.
