194002483 - K060 ABS FAILURE WARNING LIGHT ON

N.B: 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 any problems in the C-CAN the control unit warning lights which operate on this network will light up. The CAN INFORMATION check is designed to highlight precisely this

0	PRELIMINARY CHECKS	ALL OK	PROBLEMS ENCOUNTERED	ACTION
	Connect the EXAMINER diagnostic equipment and check the following at the CAN INFORMATION: No control units inactive No faulty control units no control units with faulty CAN	Move on to Step 1	1. Fault on CAN network	1. Continue following the instructions for the diagnostic equipment
		Move on to Step 1	2. Impossible to start a dialogue with the Body Computer	2. Move on to Step 7
1	CHECK USING DIAGNOSTIC EQUIPMENT	ALL OK	PROBLEMS ENCOUNTERED	ACTION
	Keeping the diagnostic equipment connected, check the following at the BRAKE NODE: No system/component errors No CAN faults	Move on to Step 2	1. System/components faulty	1. Continue following the instructions for the diagnostic equipment
		Move on to Step 2	2. Fault on C-CAN	2. Move on to Step 7
2	CHECK USING DIAGNOSTIC EQUIPMENT	ALL OK	PROBLEMS ENCOUNTERED	ACTION
	Using the Examiner check, in the Instrument Panel Node, that there are no errors and that the parameters are present.	Move on to Step 3	Presence of errors	Continue following the instructions for the diagnostic equipment
3	ELECTRICAL POWER SUPPLY CHECK	ALL OK	PROBLEMS ENCOUNTERED	ACTION
	Check that the electrical power supply for the "Instrument Panel Node" is correct.	Move on to Step 4	Electrical power supply positive and/or earth faulty.	Replace defective component (in the case of a fuse, find out what caused it to blow).
4	ELECTRICAL CONNECTIONS CHECK	ALL OK	PROBLEMS ENCOUNTERED	ACTION
	Check the electrical connections between the Body Computer and Instrument Panel, in particular that each individual pin is correctly connected.	Move on to Step 5	Electrical connections not working.	Renew the damaged electrical connections.
5	ACTIVE DIAGNOSIS CHECK	ALL OK	PROBLEMS ENCOUNTERED	ACTION
	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	ACTION
	Using the Examiner check, in the Body Computer Node ambient, that there are no errors and that the warning light status changes	Move on to Step 7	1. Impossible to connect to the Body Computer control unit.	1. Move on to Step 7
			2. Presence of errors.	2. Continue following the instructions for the diagnostic equipment.
			3. The parameter values do not change	3. Move on to Step 8
7	ELECTRICAL POWER SUPPLY CHECK	ALL OK	PROBLEMS ENCOUNTERED	ACTION
	Check that the electrical power supply for the "Body Computer Node" is correct.	Move on to Step 8	Electrical power supply positive and/or earth faulty.	Replace defective component (in the case of a fuse, find out what caused it to blow).
9	CHECK USING DIAGNOSTIC EQUIPMENT	ALL OK	PROBLEMS ENCOUNTERED	ACTION
	Check, using the Examiner, that it is possible to connect to the Body Computer Node.	Move on to Step 9	Impossible to connect to the Body Computer control unit.	Replace Body Computer Op. 5505A35 MAIN BODY COMPUTER/JUNCTION UNIT - R.R.
