STEP	CHECK TO BE PERFORMED	REMEDIAL ACTION IF THE CHECK IS NOT OK
1	Check that the connector is fitted correctly in the ignition switch Check that the connectors are fitted correctly in the switch housing	Connector(s) partially fitted and/or loose, correctly fit the connector(s) in the switch housing and/or replace the loose cable ends if necessary
2	Check for presence of 12 V on the switch Use a multimeter to check that 12 V are present between +30 and the earth (see ref. A)	No voltage at the connector ends. Determine the cause of the failed supply upstream of the steering lock switch (fuses and/or electrical system interrupted)
3	Electrical checks on the switch Disconnect the connections and check (with a multimeter) that the circuits 30-15/54, 30-INT -INT/A in the MAR-ON position on the switch are closed (see ref. B)	Circuit(s) open, replace the steering lock Op. 5520A14 IGNITION KEY LOCK BARREL - R+R
4	Electrical checks on the switch Disconnect the connections and check that the Park - Pos circuit is closed (see ref. C) (using a multimeter) with the switch in park position	Circuit open, replace the steering lock Op. 5520A14 IGNITION KEY LOCK BARREL - R+R
