System DescriptionNLEL0351The headlamp system on vehicles for North Europe contains a daytime light unit. The unit activates the fol-
lowing whenever the engine is running with the lighting switch in the OFF position:
+Low beam headlamps
+Parking, license, tail and illumination lamps
Power is supplied at all times
+through 10A fuse (No. 38, located in the fusible link and fuse box)
+to daytime light unit terminal 1 and
+to lighting switch terminal 11.
Power is also supplied at all times
+through 15A fuse
+to daytime light unit terminal 3 and
+to lighting switch terminal 5.
Power is also supplied at all times
+through 15A fuse
+to daytime light unit terminal 2 and
+to lighting switch terminal 8.
With the ignition switch in the ON or START position, power is supplied
+through 10A fuse [No. 20, located in the fuse block (J/B)]
+to daytime light unit terminal 7.
With the ignition switch in the START position, power is supplied
+through 10A fuse [No. 21, located in the fuse block (J/B)]
+to daytime light unit terminal 6.
Ground is supplied to daytime light unit terminal 9 through body grounds E24 and E73.
HEADLAMP OPERATION (DAYTIME LIGHT CANCEL OPERATION)NLEL0351S01When the lighting switch is turned to the 1st or 2nd position, power is supplied
+through lighting switch terminal 12,
+to daytime light unit terminal 11.
Then daytime light will be canceled. And the lighting system operation will be the same as no daytime light
system.
DAYTIME LIGHT OPERATIONNLEL0351S02With the engine running and the lighting switch in the OFF position, power is supplied
+from alternator terminal 3
+to daytime light unit terminal 8,
+through daytime light unit terminal 5
+to terminal 3 of headlamp LH,
+through daytime light unit terminal 4
+to terminal 3 of headlamp RH and
+through daytime light unit terminal 10
+to tail lamp and illumination.
Ground is supplied to terminal 2 of each headlamp through body grounds E24 and E73.

+When replacing belt, make sure the new belt has the same
number of ribs as the old one.
2. Inspect drive belt deflections by pushing on the belt midway
between pulleys.
3. Turn crankshaft two revolutions and re-check drive belt deflec-
tion.
Adjust if belt deflections exceed the limit.
