FUNCTIONAL DESCRIPTIONThe radio P020 receives a direct battery power supply - pin 44 - through the line for fuse F36 of the Body Computer M001. Pin 43 of P020 is earthed. The CAN reaches pin 12 and 2 of radio P020 and connects it to the Body Computer M001 and the other system nodes. The Body Computer M001 is connected to the radio controls on the steering wheel through the clock spring D047: pin 53 of connector H provides the reference earth at pin 6 of D047; pin 51 of connector H of M001 receives the signals from the buttons to the right of the steering wheel, whilst pin 38 of connector H of M001 receives the signals from the buttons to the left of the steering wheel. The Body Computer M001 - connector A - receives a direct power supply from the battery through the line protected by maxi fuse F01 of the engine compartment junction unit B001. The Body Computer M001 receives an ignition-operated power supply (INT) at pin 2 of connector G: this signal is used, amongst other things, to "wake up the network". Pin 11 of connector G of M001 provides the Body Computer with a reference earth. USB port P157 of connector B is connected to radio P020 - connector B. The socket also receives ignition-operated power supply (INT) - for its lighting - at pin 8 of connector A through the line of fuse F49 of Body Computer M001.
