199000840 - K060 ABS FAILURE WARNING LIGHT ON

The brake node sends the ABS warning light on message via the C-CAN to the Body Computer which makes it available via the gateway to the Instrument Panel Node through the B-CAN.

If there are problems in the C-CAN, the control unit warning lights for this network will light up. The "CAN INFORMATION" check is designed for this eventuality

		Results of the tests
0	PRELIMINARY CHECKS	All OK	Problems encountered	Operation
	Connect an EXAMINER and check the following on CAN NETWORK INFORMATION:- No control units inactive- No faulty control units- No control units with faulty CAN line	Move on to Step 1	1. Fault on CAN network2. Communication impossible with the Body Computer	1. Continue following the instructions for the diagnostic equipment2. Move on to Step 7
1	CHECK USING DIAGNOSTIC EQUIPMENT	All OK	Problems encountered	Operation
	Keeping the diagnostic instrument connected, check the following on the BRAKE NODE:- No system/component errors- No CAN faults	Move on to Step 2	1. System/components faulty2. Fault on C-CAN network	1. Continue following the instructions for the diagnostic equipment2. Move on to Step 9
2	CHECK USING DIAGNOSTIC EQUIPMENT	All OK	Problems encountered	Operation
	Using the Examiner check, in the Instrument Panel Node ambient, that there are no errors and that the parameters are present.	Move on to Step 3	Presence of errors	Continue following the instructions on the diagnostic instrument
3	ELECTRICAL POWER SUPPLY CHECK	All OK	Problems encountered	Operation
	Check the electricity supply to the Instrument Panel Node is correct.	Move on to Step 4	Fault in positive electrical supply and/or earth	Replace defective component (in the case of a fuse, find out what caused it to blow).
4	CHECK ELECTRICAL CONNECTIONS	All OK	Problems encountered	Operation
	Check the wiring between the Body Computer and the Instrument Panel. In particular, check that each individual pin is properly connected.	Move on to Step 5	Electrical connections not operational	Renew the damaged electrical connections
5	ACTIVE DIAGNOSIS CHECK	All OK	Problems encountered	Operation
	With the Examiner in the Instrument Panel Node ambient check that the ABS warning light is correctly activated in Active Diagnosis.	Move on to Step 6	The ABS warning light does not flash	Replace the Instrument Panel    Op. 5560B10 CONTROL PANEL - R+R
6	CHECK USING DIAGNOSTIC EQUIPMENT	All OK	Problems encountered	Operation
	Using the Examiner check, in the Body Computer Node mode, that there are no errors and that the parameters are present.	Move on to Step 9	1. Impossible to connect to the Body Computer control unit.2. Presence of errors3. The parameters do not change	1. Move on to Step 72. Continue by following the instructions on the diagnostic instrument3. Move on to Step 9
7	ELECTRICAL POWER SUPPLY CHECK	All OK	Problems encountered	Operation
	Check the electricity supply to the Body Computer Node is correct.	Move on to Step 8	Fault in positive electrical supply and/or earth	Replace defective component (in the case of a fuse, find out what caused it to blow).
8	CHECK USING DIAGNOSTIC EQUIPMENT	All OK	Problems encountered	Operation
	Use an Examiner to check the possibility of connection to the Body Computer Node	Move on to Step 6	Impossible to connect to the Body Computer control unit.	Replace Body Computer    Op. 5505A32 BODY COMPUTER - R.R
9	CHECK ON CORRECT OPERATION	All OK	Problems encountered	Operation
	Check that the fault is no longer present	End of diagnosis	The fault persists	Replace the electrohydraulic unit - ABS electronic control unit    Op. 3340A12 ABS HYDRAULIC AND ELECTRONIC CONTROL UNIT - R.R.
