Z83 SUPPLY VOLTAGE ERROR - Fiat - PANDA - eLearn

169000653 - Z83 SUPPLY VOLTAGE ERROR

The diagnostic equipment signals the following error: "C1800 - Supply voltage"

This error is signalled if the control unit detects a battery voltage that is too high or too low

1	POWER SUPPLY CIRCUIT CHECK	All OK	Problems encountered	Operation
	Check that the supply voltage at the battery terminals is correct.Check the power supply wiring from the battery to the ABS control unit See E7020 ABS there should be no drop in voltage between the battery and the control unit	Move on to Step 2 1	Battery voltage not correct Drop in voltage in the wiring	Recharge the battery, if necessary, replace it Op. 5530B10 BATTERY - R+R Renew the wiring, if necessary, replace the faulty components
2	CHECK ON CORRECT OPERATION	All OK	Problems encountered	Operation
	Delete the errors using the diagnostic equipment.Carry out a road test See Test 3340OA A.B.S. SYSTEM ACTUATION CHECKto ensure that the control unit checks whether there are any errors still present.Return to the workshop and check that the fault is no longer present using the diagnostic equipment.	End of diagnosis
