1	BATTERY VOLTAGE CHECK	ALL OK	PROBLEMS ENCOUNTERED	ACTION
	Check correct battery voltage	Move on to Step 2	Battery voltage incorrect.	Restore the correct voltage.
2	CHECK USING DIAGNOSTIC EQUIPMENT	ALL OK	PROBLEMS ENCOUNTERED	ACTION
	Connect the Examiner diagnostic equipment and check whether the following parameters are present and that there are no errors in the Body Computer mode	Move on to Step 4	1. Impossible to connect to the control unit.2. Presence of errors	1. Replace Body Computer Op. 5505A35 MAIN BODY COMPUTER/JUNCTION UNIT - R.R.2. Move on to Step 3
3	ACTIVE DIAGNOSIS CHECK	ALL OK	PROBLEMS ENCOUNTERED	ACTION
	With the Examiner in the Body Computer mode check that the function in question is correctly activated in Active Diagnosis.- Left/right main beam headlamps control	Move on to Step 5	1. One of the main beams is not activated as the bulb is defective2. Both of the bulbs are not activated due to defective wiring between the engine compartment junction unit and the bulbs3. The lights are not activated by the steering column switch unit	1.Replace the bulb2.Restore the correct wiring3.Move on to Step 4
4	CHECK USING DIAGNOSTIC EQUIPMENT	ALL OK	PROBLEMS ENCOUNTERED	ACTION
	Using the Examiner check the variation in the status of the parameters by activating the appropriate controls in the Steering Wheel Controls Node ambient.The parameters involved are:- Dipped/main beam headlamps control- Check that the steering column switch unit lights are working properly	Move on to Step 5	1. Impossible to connect to the control unit.2. No variation in the state of the parameters under consideration is detected	1. Replace the Steering Wheel Controls Node control unit.2. Replace the steering column switch unit Op. 5550A10 STALK UNIT ASSEMBLY - R+R
5	CONTROL UNIT ELECTRICAL CIRCUIT CHECK	ALL OK	PROBLEMS ENCOUNTERED	ACTION
	Check:- Condition of fuses- Wiring between steering column switch unit and Body Computer See E2012 MAIN BEAM HEADLAMPS	Move on to Step 6	1.Protective fuse/s blown2.Wiring defective	1. Replace the component involved (in the case of a fuse, find out what caused it to blow).2. Restore the correct wiring.
6	CONTROL UNIT ELECTRICAL CIRCUIT CHECK	ALL OK	PROBLEMS ENCOUNTERED	ACTION
