FUNCTIONAL DESCRIPTION

The Body computer M001 receives a direct battery power supply (pin 1 of connector A) protected by fuse F01 of the engine compartment junction unit B001 (pin 18 of connector B); it also receives an ignition-controlled power supply (INT) at pin 11 of connector E. The latter supply is used, amongst other things, for waking up the network.The Body computer M001 is also connected to the driver''s side dashboard earth C015 via pins 9 and 10 of connector E.The following nodes are connected to the Body Computer M001 via the C-CAN high speed network:

  • the Bluetooth control unit M162 (on the Blue&Me version);
  • the diagnostic socket R010;
  • electric steering control unit M086;
  • slewing control unit M091;
  • the ESP braking system control unit M051;
  • the engine management control unit M010.
In detail, the Body computer M001 is connected:

  • from pins 24 and 26 of connector D with the Bluetooth control unit M162 (pins 1 and 2 of connector B);
  • from pins 25 and 27 of connector D with the diagnostic socket R010 (pins 6 and 14);
  • from pins 44 and 45 of connector B, with the electric steering control unit M086 (pins 2 and 3 of connector B).
The control unit M086 is connected, via pins 7 and 8 of connector B, with pins 4 and 2 of the slewing control unit M091; the latter is then connected, via pins 5 and 3, with pins 26 and 14 of the ESP braking system control unit M051.The ESP braking system control unit M051 is, in turn, connected, via pins 27 and 15, with the engine management control unit M010 (pins 50 and 49 of connector A for the 1.2 petrol versions; pins 89 and 88 of connector A for the 1.4 petrol version; pins 64 and 40 of connector A for the 1.3 JTD version).The following nodes are connected to the M001 Body Computer via the B-CAN low speed network:

  • the instrument panel E050;
  • the radio P020;
  • the Bluetooth control unit M162 (on the standard and Blue&Me versions);
  • the Air Bag control unit M060;
  • the climate control system control unit M070;
  • the diagnostic socket R010;
  • the parking sensors control unit M084.
On versions with optional radio preparation, there is no B-CAN for the radio.
In detail, the Body computer M001 is connected:

  • from pins 57 and 58 of connector B, with the climate control system control unit M070 (pins 10 and 9 of connector A);
  • from pins 17 and 22 of connector D with the radio P020 (pins A3 and A1 of connector A);
  • from pins 16 and 21 of connector D, with the Air Bag control unit M060 (pins 7 and 8 connector A);
  • from pins 34 and 49 of connector F, with the parking sensor control unit M084 (pins 7 and 14 of connector A);
  • from pins 37 and 52 of connector F with the Bluetooth control unit M162 (pins 14 and 30 of connector A for the Blue&Me version);
  • from pins 19 and 23 of connector D with the diagnostic socket R010 (pins 9 and 1).
This version does NOT include individual diagnostic lines (dedicated K line) that monitor the individual control units.
