VOLTAGE CHART

Measurement condition (Battery voltage is 12 V)	Tester connection	Switch condition	Specified condition
Battery positive (+) → Terminal 1 (+B) Battery negative (-) → Terminal 2 (GND)	1 (+B) - 4 (LH) 1 (+B) - 5 (RH)	0	10.4 to 11.2 V
		1	9.2 to 9.9 V
		2	7.9 to 8.6 V
		3	6.6 to 7.3 V
		4	5.3 to 6.0 V
		5	4.0 to 4.8 V

If the result is not as specified, replace the headlight leveling switch.

Inspect the illumination of the switch.

Apply battery voltage to the headlight leveling switch connector.

Check that the illumination comes on.
