EPLACING AND INITIALIZING NETWORK NODES
Some of the CAN nodes are programmed with default settings which the customer will find on
purchasing the vehicle.
The nodes storing this information are:
•
BCM: Body Computer;
•
IPC: Instrument Panel Node;
•
RRM and LTM: Radio Receiver Node;
•
ACM: Climate Control Unit Node;
•
SDM: Airbag Node.
•
PAM: Parking sensor module
•
TPM: Tyre pressure sensor module
If the Body Computer is being replaced, an "identical copy" of the Body Computer must be obtained
from the Parts Dept. as a V.O.R. order supplying the vehicle chassis number: this copy will contain all
the default settings entered on a new vehicle, which are stored in the Spare Parts database for the
vehicle chassis number.
If the other nodes described above are being replaced, Spare Parts will send a blank component:
once fitted, the initial default data must be transferred to it by carrying out the PROXY ALIGNMENT
procedure using Examiner.
L
OGISTIC MODE
There is software inside the Body Computer that excludes all the vehicle's electrical loads, except the
main functions (vehicle starting, lights). This function makes it possible to save battery energy which is
useful when the vehicle is parked in compounds before being sold.
The function must be disabled in the workshop before the vehicle is handed over to the customer
Deactivation procedure
The procedure is as follows:
•
Connect the terminal of the diagnosis device to the vehicle's EOBD socket and turn the key to
MAR;
•
check that the "alternator recharging" warning light is flashing, to indicate that the low
consumption "Logistic Mode" is active;
•
deactivate the low consumption supply mode by carrying out the procedure using the Body
Computer diagnosis equipment;
•
the Body Computer and all control units involved in performing this operation, on receiving the
CAN message, will restore their full operation and send a confirmation message to the Body
Computer node;
•
delete the error memory in all control units with a diagnosis function;
•
switch off and then on again (keyOFF - keyON);
•
check that the "alternator recharging" warning light is on constantly.

OMPUTER NODE
The Body Computer Node (NBC) is an electronic component which manages the vehicle's serial
networks and the basic functions of the vehicle (interior and exterior lighting, diagnosis, windscreen
wipers, heated rear window, locking/unlocking of doors, fuel level, management and acquisition of
ignition key status, etc.)
It houses the communication gateway between the B-CAN and C-CAN and also carries out
interconnection functions between cab, front and dashboard wiring.
It is located under the dashboard to the left.
