RH or LH adjustment cannot be carried out with low beams on

Low beam alignment button on exterior lights control panel sends a command directly to the Instrument Panel Node (NQS), which controls the actuator motors by sending different voltage signals.

		Results of the tests
1	CHECKING ELECTRICAL EQUIPMENT	All OK	Problems met	Operation
	Check the continuity of the control signal wiring between the junction node and the LH or RH headlamp using a multimeter to measure the voltage at the headlamp connector See   E3080  HEADLAMP AGLINMENT CORRECTOR	Continue to Step 2	Wiring broken	Renew the wiring See   E3080  HEADLAMP AGLINMENT CORRECTOR
2	CHECKING ELECTRICAL EQUIPMENT	All OK	Problems met	Operation
	Check the continuity of the actuator motor positive supply wiring between the junction node and the LH or RH headlamps measuring the supply voltage at the headlamp connector using a multimeter See   E3080  HEADLAMP AGLINMENT CORRECTOR	Continue to Step 3	Wiring broken	Renew the wiring See   E3080  HEADLAMP AGLINMENT CORRECTOR
3	CHECKING ELECTRICAL EQUIPMENT	All OK	Problems met	Operation
	Check earth connection of RH or LH motor See   E3080  HEADLAMP AGLINMENT CORRECTOR	Continue to Step 4	Wiring broken	Renew the wiring See   E3080  HEADLAMP AGLINMENT CORRECTOR
