1	SUPPLY CIRCUIT CHECK	All OK	Problems met	Operation
		Results of the tests
	Check that the supply voltage at the battery terminals is correct.Check the supply wiring from the battery to the ABS control unit See E7020 ABS : there should not be a drop in voltage between the battery and the control unit	End of diagnosis	Battery voltage incorrect	Recharge the battery, if necessary, replace it. Op. 5530B10
		End of diagnosis	Fall in wiring voltage	Renew the wiring, if necessary, replace the faulty components
2	CHECK ON CORRECT OPERATION	All OK	Problems met	Operation
	Delete the errors using the diagnostic equipment.Carry out road See Test 3340A ABS intervention check to make the control unit check whether there are still errors present. Return to the workshop and check that the fault is no longer present using the diagnostic equipment.	End of diagnosis	.
