DescriptionThis device allows maximum ease of manoeuvring during parking; with reverse gear engaged, it indicates if the driver is approaching an obstacle that could be outside his field of vision, as illustrated in the diagram below.The system operates in accordance with the ultrasound 'sonar' principle: four ultrasound transducers are located in the rear bumper. They send signals to a control unit, which processes this information and determines the distance of possible obstacles. A loudspeaker controlled by the control unit emits an intermittent tone, proportional to the distance of the obstacle detected. The control unit is activated when reverse gear is engaged: under these conditions it energizes the transducers and sends them a signal request, and receives response signals from them.The control unit emits a signal with intermittent tone: the frequency of this sound increases as the bumper comes close to an obstacle: when the calculated distance falls below 25 cm, the sound becomes acute and constant.If the distance measured from the obstacle increases, or if the driver disengages reverse gear, the sound stops. If the distance measured from the obstacle remains constant, the sound ceases after about 3 seconds.

Functional description Parking sensor control unit M84 is supplied pin 1 of connector A by the ignition-operated line (INT/A) for relay T24 of B45 protected by fuyse F78; Pin 8 of connector A is earthed. Pin 6 of connector A of M84 receives the reverse gear engaged signal SeeE2022 REVERSING LIGHTS . Pin 1 of connector A of M84 receives the speedometer signal from the instrument E50 pin 5 of connector B. The parking sensor P44 buzzer is connected to pins 2 and 10 of connector A of control unit M84. Pin 5 receives an inhibition signal if a trailer is connected via coupling D73 SeeE2050 TRAILER WIRING . The four parking sensors K97 are connected to connector C of control unit M84 : pin 1 supplies a reference earth, pin 6 the power supply, pins 5, 3, 2 and 4 are connected to sensors K97A , K97B , K97C and K97D . Self-diagnostic data can be read by connecting the unit to connector R10 pin 13: this receives signals from pin 12 of connector A of control unit M84 through the relevant tester line SeeE8010 DIAGNOSTIC MULTIPLE CONNECTOR .
