Description and Operation Vehicles without rail common rail injection
    1-Turbocompresseur/collecteur 
 The turbocharger is composed of two elements , a turbine and a compressor both mounted on a single axis and accommodated in a casing . The turbocharger and the exhaust manifold is an integral unit , and although it is possible to separate them, they are not provided separately and should not be separated. Turbocharger bearings are supplied with engine oil through the oil supply pipe . The oil returns to the oil pan through the oil return pipe . The turbine of the turbocharger is mounted on the exhaust manifold and uses the energy of the exhaust gas to drive the compressor . The compressor draws air through the heat exchanger. The turbocharger is controlled by means of a discharge valve . The relief valve diverts a portion of exhaust gas from the turbine . The discharge valve is controlled by a control solenoid relief valve which is preset at the time of manufacture and should in no way suffer changes. Vehicles with common rail injection rail

 6-An oil supply hose turbocharger
 7 - return pipe oil turbocharger
8 - O-ring pipe turbocharger oil return
9 - fixing screw feed pipe turbocharger oil
10 - sealing washers pipe turbocharger oil supply

The vacuum diaphragm adjustment vane turbocharger vane adjusts the turbocharger according to the vacuum provided by the solenoid regulating vane turbocharger . The valve adjustment palettes turbocharger is controlled by the engine management ( PCM ) . The actual boost pressure of the turbocharger is controlled by the setting of the turbocharger vane , making the use of a control valve discharge valve unnecessary. The vacuum diaphragm adjustment vane turbocharger is preset at the time of manufacture and should in no way suffer changes.

Diagnosis and Testing Refer to Wiring Diagrams Section 307-01, for schematic and connector information. General Equipment  diagnostic equipment Inspection and Verification Verify the customer concern. Visually inspect for obvious signs of mechanical or electrical damage. Visual Inspection Mechanical Electrical Fluid level too high/low Poor condition of fluid Fluid leak Damaged shift mechanism/linkages Damaged automatic transmission/ transaxle casing Fuse(s) Relay(s) Wiring harness Electrical connector(s) Selector lever module Transmission control module (TCM) If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step If the cause is not visually evident, verify the symptom and refer to the Ford diagnostic equipment to diagnose the system.

Contrôle et vérification Note : Le module électronique générique (GEM) fait partie du boîtier électrique central (CJB). Note : Si le module GEM est remplacé, le module neuf doit être configuré après la pose. A cet effet, les données spécifiques au véhicule sont extraites du module à remplacer à l'aide de l'équipement de diagnostic et sont transférées dans le module neuf. Note : Avant d'extraire les données spécifiques au véhicule, s'assurer que toutes les connexions électriques du véhicule sont de nouveaux raccordées, de sorte que le module et l'outil de diagnostic puissent communiquer correct
