CONNECT OPERATIONAL DESCRIPTION

Operational Description

The body computer node M001 provides a direct supply, from pin 1 connector D, to the radio Connect P020, pin 4 connector D, via the line protected by fuse F11 of the body computer.

It converses, from pins 5 and 2 of connector D, via the CAN, with the milometer and warning lights control unit node M140, at pins 6 and 3 and with the instrument panel E050.

A power supply for the CAN is received at pin 6 connector D from the body computer node M001 from pin 3 connector D from the line protected by fuse F20 of the control unit.

The radio P020 is connected (switched power supply) to the aerial P025 from pin 3 connector D and to earth at pin 8.

The Connect radio P020 is connected, via connector C, to the various speakers located inside the vehicle:

• from pins 1, 5 it is connected to the speakers P048 (right rear tweeter) and P121 (right rear speaker);
• it is connected, from pins 2, 6, to the speakers P036 (speaker in right front door) and P046 (right front tweeter);
• it is connected, from pins 3, 7, to the speakers P035 (speaker in left front door) and P045 (left front tweeter);
• from pins 4, 8 it is connected to the speakers P047 (left rear tweeter) and P120 (left rear speaker);

Pins 2 and 8 of connector A are connected to speaker P035 also used for the hands-free function in the telephone mode.

The Connect P020 is connected, from pins 3, 9 connector A, to the microphone P027; pin 3 is the reference earth, whilst pin 9 is the audio signal input.

Pins 1, 7 supply the outside fan N160.

The multifunction screen M172 displays the information supplied by the Connect in a graphic format. Pins 6 and 4 of the screen are connected at pins 5 and 12 connector A of the Connect P025 and form a CAN connection; pin 3 of M172 is connected to pin 6 connector A of the Connect P020 (stand-by signal). Pins 1, 2 are connected to pins 1, 7 connector D of the Connect P020 and receive the power supply and the reference earth, respectively.

The radio P020 is connected, via connector B, to the CD changer P075. Pins 7, 2 and 9 are used for the exchange of data via the CAN. From pins 1, 3 the radio P020 provides the CD changer with a reference earth and direct battery supply, respectively. Pins 4 and 10 are the left and right audio inputs, respectively. Pin 8 is the earth reference of the audio channel.

The control panel M160 is connected to the Connect P020 at pins 12, 11, 6 of connector B via the CAN.

The radio/GSM aerial P111 is connected to connector E of P020.

It is possible, via the steering wheel node M093, to control several of the radio functions using the radio controls on the steering wheel; this information is sent by the steering wheel node control unit M093 to the body computer node M001, via the CAN which connects the two control units.
