System Description
The headlamp system on vehicles for North Europe contains a daytime light control unit. The unit activates
the following whenever the engine is running with the lighting switch in the OFF position:
I Low beam headlamps
I Parking, license, tail and illumination lamps
Power is supplied at all times
I through 10A fuse (No. 34, located in the fuse and fusible link box)
I to daytime light control unit terminal 1 and
I through 40A fusible link (No. C, located in the fusible link and fuse box)
I to ignition switch terminal 1.
Power is also supplied at all times
I through 15A fuse (No. 36, located in the fusible link and fuse box)
I to daytime light control unit terminal 5 and
I to lighting switch terminal 5.
Power is also supplied at all times
I through 15A fuse (No. 37, located in the fusible link and fuse box)
I to daytime light control unit terminal 7 and
I to lighting switch terminal 8.
With the ignition switch in the ON or START position, power is supplied
I through 10A fuse [No. 11, located in the fuse block (J/B)]
I to daytime light control unit terminal 12.
With the ignition switch in the START position, power is supplied
I to daytime light control unit terminal 8.
Ground is supplied to daytime light control unit terminal 10 through body grounds M33 and M754.
HEADLAMP OPERATION (DAYTIME LIGHT CANCEL OPERATION)
When the lighting switch is turned to the 1st or 2nd position, power is supplied
I through lighting switch terminal 12,
I to daytime light control unit terminal 3.
Then daytime light will be canceled. And the lighting system operation will be the same as no daytime light
system.
DAYTIME LIGHT OPERATION
With the engine running and the lighting switch in the OFF position, power is supplied
I from alternator terminal 1
I to daytime light control unit terminal 2,
I through daytime light control unit terminal 9
I to terminal 2 of headlamp LH,
I through daytime light control unit terminal 11
I to terminal 2 of headlamp RH and
I through daytime light control unit terminal 6
I to tail lamp and illumination.
Ground is supplied to terminal 3 of each headlamp through body grounds F36, F47 (LH) and M33, M754 (RH).
