Diagnostic et essais Se reporter au chapitre 206-09A, du Manuel des schémas électriques pour les schémas et les informations sur les connecteurs. Equipement d'atelier et outillage standard Contrôle et vérification Contrôler l'incident décrit par le client. Rechercher visuellement les signes apparents de dommages mécaniques ou électriques. Tableau de contrôle visuel Mécanique Electrique Capteur(s) de roue Couronne(s) de capteur de vitesse de roue Fusible(s) Connecteur(s) Faisceau(x) de câblage Si le contrôle révèle un incident évident, le corriger (si possible) avant de passer à l'étape suivante. Si l'origine de l'incident n'est pas visuellement évidente, brancher l'équipement de diagnostic Ford sur le connecteur de liaison de données et sélectionner le véhicule à contrôler depuis le menu de l'outil de diagnostic.

1-----Yaw rate sensor and accelerometer 2-----Steering wheel rotation sensor 3-----Hydraulic control unit (HCU) and stability assist module assembly The stability assist module adds a further function known as electronic stability program (ESP) to the anti-lock brake system (ABS) and includes a traction control function. Whereas the ABS prevented wheel lock up during braking, the traction control function controls wheel slip during acceleration (longitudinal dynamics) and the ESP stabilizes the vehicle about its vertical axis. Sensors measure the position of the steering wheel, the pressure in the brake master cylinder, the yaw velocity (yaw rate) and the acceleration transverse to the vehicle (lateral acceleration). This makes it possible to compare the driver's intention with the momentary vehicle behaviour so that in the event of the vehicle becoming unstable, ESP can initiate the appropriate corrective action. The ESP recognizes critical d...

The active roll stabilisation of the Mercedes-Benz ACTIVE CURVE SYSTEM boosts driving comfort significantly: When cornering, the stabiliser bars are actively impacted and keep the torsional moment constant.      Enlarge   ACTIVE CURVE SYSTEM      Enlarge   ACTIVE CURVE SYSTEM The roll distribution is variable to enable the vehicle to be adapted to almost any situation. The driver has the feeling of gliding on rails, particularly in vehicles with a high centre of gravity.        Enlarge   ACTIVE CURVE SYSTEM In off-road environments, the system guarantees improved axle roll by decoupling the two stabiliser bars at the front and rear axles.

Inadequate following distances, inattentiveness on the part of the driver and unexpected, abrupt traffic standstills are the most common causes of rear-end collisions. Radar-based DISTRONIC PLUS adaptive cruise control provides a remedy here.    Enlarge DISTRONIC PLUS The system keeps you automatically at a distance from the vehicle in front and makes a major contribution towards minimising the risk of rear-end collisions by identifying potentially dangerous situations and responding accordingly.    Enlarge    Enlarge DISTRONIC PLUS The cutting-edge radar technology employed by DISTRONIC PLUS monitors the situation ahead of the car and is able to recognise an impending accident. Behind the front bumper panels there are two short-range radar sensors covering a range from 20 cm to 30 metres and a scanning angle of 80 degrees. The long-range radar is concealed behind the radiator grille. A...

The ABS No obvious magnetic sensors check After Halloween , it is the anti-lock brake problems haunt our garages. Why ? As the sensors are the key elements of the system, they are also the most likely to default . The snow mixed with salt gives a saltwater solution that puts to the test the speed sensor wheel, particularly inductive (magnetic) sensor .

The mixed salt water to seep into the smallest cracks sensors to betray management system . When the vehicle is delivered to the customer , the ABS warning light could suddenly turn . And now back to the studio, not happy at all ! The management system is the first verification of these sensors when the ignition is switched to "on" ( key ON) . The management system then checks if the sensors have a voltage leakage to ground. This is made possible by a low voltage (about 2.5 volts to 5 volts) se...

Removal and Installation General Equipment Audio unit removal tools (GV3301) Worldwide Diagnostic System (WDS) NOTICE: If the navigation system display module is to be removed for testing or new component installation, remove any audio media (if possible) from within the navigation system display module and return it to the customer. Failure to follow this instruction may result in damage to the navigation system display module. NOTE: When installing the audio unit removal tools, make sure that the wording on the audio unit removal tools is followed, TOP L (left-hand) indicates the top of the tool, left-hand side of the removal tool and TOP R (right-hand) indicates the top of the tool, right-hand side of the removal tool. 1. Remove the components in the order indicated in the following illustration(s) and table(s). Item Part Number Description 1 - Audio unit removal tools 2 - Navigation system display module See Removal...

a Hall effect sensor is a sensor that will allow to measure ( detect ) a change in electromagnetic field, a magnet or a piece of iron magnet (or not) causes a change in the magnetic field , or disturbance power a piece of iron I hope to answer your question
