CONTROLLED SUSPENSION OPERATIONAL DESCRIPTION

Operational Description

The controlled suspension control unit M046 is supplied by the line controlled by the ignition (INT) vprotected by fuse F49 of the junction unit under the dashboard B002.

The control unit is connected by a series of sensors to the following functions:

• by pins 11 and 16, respectively, for the supply and earth and by pin 37 for the left front vertical acceleration sensor on the bodyshell K006;
• by pins 9 and 15 and by pin 36 to the right front vertical acceleration sensor on the bodyshell K007;
• by pins 12 and 17 and by pin 35 to the left front vertical acceleration sensor on the bodyshell K008;
• by pins 10 and 20 and by pin 34 to the right front vertical acceleration sensor on the bodyshell K009;
• by pins 13 and 18 and by pin 39 to the lateral acceleration sensor K011;
• by pins 14 and 19 and by pin 38 to the rear vertical acceleration sensor on the bodyshell K012. According to the signals received from the above mentioned sensors and the speedometer signal received at pin 31 of the Body Computer M001 (pin 28 of connector B), the controlled suspension control unit M046 determines the adjustment of the suspension by means of special actuators:
• from pin 30 of the brake pedal switch I030.

According to the signals received from the above mentioned sensors and the speedometer signal received from pin 31 of the Body Computer M001 (pin 28 of connector B), the controlled suspension control unit M046 determines the adjustment of the suspension by means of special actuators:

• by pins 5 and 25 to the right front actuator N096;
• by pins 4 and 24 to the left front actuator N097;
• by pins 3 and 23 to the right rear actuator N098;
• by pins 2 and 22 to the left rear actuator N099;

The braking system control unit M051, supplied by the line from the battery protected by fuse F02 of the engine compartment junction unit B001, transmits the speedometer signal from pin 16 to the Body Computer M001 (pin 7 of connector A).

It is possible to show a device failure message on the display by means of a special signal transmitted from pin 6 of the controlled suspension control unit M046 to the instrument panel M050 (pin 8 of connector A).
