5 COMPONENTS Description of components XF 95 series 2.7 PROXIMITY SENSORS The vehicle has a number of proximity sensors, such as: - sensor under the clutch pedal for engine management - cab lock sensor - mechanical rear axle lifting gear 2 Inductive proximity sensors An alternating electromagnetic field is generated by a pulsating current in a coil (oscillation). If a metal object is introduced into the electromagnetic field, eddy currents will occur in that metal object. These eddy currents will ‘damp’ the magnetic field in the coil, so that the current taken up in the coil will change. This change results in an output voltage.
W 5 01 014 Inspection Placing a metal object in front of the sensor (inductive sensor) makes it possible to check the output voltage using a multimeter set to the direct voltage range. E500551 2.8 STALK SWITCH The stalk switches in the XF vehicle series have been re-designed. Both the design and the functionality have changed. The advantages of the new switches are: - Switches are short-circuit proof - Longer service life thanks to use of reed switches - The intarder function has been integrated into the right-hand switch, so there are now two switches on the steering column - All cruise-control and speed-control functions have been integrated into the right-hand stalk switch 2-10 200303
