Checks.
IMPERATIVE: Respect the safety and cleanliness specific to high pressure diesel injection
engines.
Preliminary operations.
WARNING: Prior to any intervention, check the connections of the turbocharger pressure
regulation actuators.
NOTE:If an air flow fault is memorised by the diagnostic tool, refer to the chapter "Air flow from
the turbochargers".
Turbo pressure sensor.
Remove the engine cover.
Disconnect the connector "a".
Remove the turbo pressure sensor (1).

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.

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.

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.
