Both the headlamps come on, the initial test is carried out and the remain immobile, facing downwards
1CHECK ON ALIGNMENT SENSOR WIRINGALL OKPROBLEMS ENCOUNTEREDACTION
Check the condition of the wiring for the alignment sensors.Check that the alignment sensors are correctly fitted and, in particular, that the fastening of the bracket with the connecting rod is correctMove on to Step 21. Wiring short circuited with +Vbatt or to earth1. Restore insulation for wiring    See E2011 DIPPED HEADLAMPS
2. Wiring broken2. Restore or, if necessary, replace the wiring
3. Mechanical installation of front sensor (brackets, connecting rods) incorrect3. Refit front sensor correctly    Op. 5540C42 SENSOR FOR CORRECTING/ALIGNING GAS DISCHARGE LIGHTING UNITS ON FRONT SUSPENSION - R R
4. Mechanical installation of rear sensor (brackets, connecting rods) incorrect4. Refit rear sensor correctly    Op. 5540C46 SENSOR FOR CORRECTING/ALIGNING GAS DISCHARGE LIGHTING UNITS ON REAR SUSPENSION - R.R.
