FUNCTIONAL DESCRIPTION

The central diagnosis socket R010 receives a direct battery power supply at pin 16 from the line protected by fuse F36 of the Body Computer M001; pins 4 and 5 of R010 are earthed.

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 (INT) power supply at pin 11 of connector E, whilst pin 9 of connector E of M001 provides the Body Computer with a reference earth.

Pins 6 and 14 are connected to the C-CAN: this network controls and diagnoses the engine management control unit M010 and the ABS-VDC control unit M050, the yaw sensor K074 and the electric steering control unit M086.

In LPG versions, a special diagnosis connector R022 allows the self-diagnosis data from control unit M018 to be read, connecting to pins 10, 11, 38 and 39 of M018. This is then connected to the K line of connector R10, dedicated to the engine management - pin 7.
