8	CHECK ON CORRECT OPERATION	All OK	Problems met	Operation
	Check that the fault is no longer present	End of diagnosis	The fault persists	Continue to Step 1

The Engine Management Node sends the message via the C-CAN to the Body Computer which makes it available, via the B-CAN, to the Instrument Panel Node.

Any faults in the C-CAN light up the control unit warning lights which communicate on this network. The CAN information check is designed precisely for this purpose

1	PRELIMINARY CHECKS	All OK	Problems met	Operation
		Results of the tests
	Connect the Examiner diagnostic equipment and check for the following at the CAN Information: Node(s) not activated Node(s) faulty Node(s) with CAN error	Continue to Step 6	Impossible to converse with the Body Computer	Continue to Step 2
			Instrument Panel Node not activated and/or faulty	Continue to Step 5
			Engine Managment node not activated and/or faulty	Continue to Step 9
			Presence of faults in the CAN	Continue to Step 13
2	CHECK WITH DIAGNOSTIC EQUIPMENT	All OK	Problems met	Operation
	Using the Examiner check, the possibility of connecting with the Body Computer Node and that there are no errors and the following parameters are present.	Continue to Step 1	Impossible to connect with the Body Computer control unit.	Continue to Step 3
		Continue to Step 1	There are errors	Continue according to the instructions for the diagnostic equipment
3	ELECTRIC POWER SUPPLY CHECK	All OK	Problems met	Operation
	Check that the electrical supply for the Body Computer Node is correct and check the wiring between the nodes, in particular that each individual pin is correctly connected	Continue to Step 4	Positive and/or earth electrical power supply faulty	Replace the component involved (if a fuse is involved, search for the cause of the problem)
		Continue to Step 4	Electrical connections not working	Restore the correct operation of the damaged wiring
4	CHECK WITH DIAGNOSTIC EQUIPMENT	All OK	Problems met	Operation
	Using the Examiner, check the possibility of connecting with the Body Computer Node	Continue to Step 2	Impossible to connect with the Body Computer	Replace the Body Computer Op. 5505A32
