System Description (For Canada)
EKS006VD
The headlamp system for Canada vehicles contains a daytime light control unit that activates the high beam
headlamps at approximately half illumination whenever the engine is running. If the parking brake is applied
before the engine is started the daytime lights will not be illuminated. The daytime lights will illuminate once the
parking brake is released. Thereafter, the daytime lights will continue to operate when the parking brake is
applied. If the daytime light control unit receives a ground signal from the generator, the daytime lights will not
be illuminated. The daytime lights will illuminate once a battery positive voltage signal is sent to the daytime
light control unit from the generator.
Power is supplied at all times
●
through 15A fuse (No. 38, located in the fuse and fusible link box)
●
to daytime light control unit terminal 3 and
●
to lighting switch terminal 5.
Power is also supplied at all times
●
through 15A fuse (No. 37, located in the fuse and fusible link box)
●
to daytime light control 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. 5, located in the fuse block (J/B)]
●
to daytime light control unit terminal 12.
With the ignition switch in the START position, power is supplied

●
to daytime light control unit terminal 1.
Ground is supplied to daytime light control unit terminal 9 through body grounds E12 and E54.
HEADLAMP OPERATION
Low Beam Operation
When the lighting switch is turned to the headlamp ON (2ND) position, low beam (B), power is supplied
●
from lighting switch terminal 10
●
to headlamp RH terminal D and
●
to daytime light control unit terminal 4.
Ground is supplied to headlamp RH terminal E through body grounds E12 and E54.
Also, when the lighting switch is turned to the headlamp ON (2ND) position, low beam (B), power is supplied
●
from lighting switch terminal 7
●
to headlamp LH terminal D.
Ground is supplied
●
to headlamp LH terminal E
●
from daytime light control unit terminal 7
●
through daytime light control unit terminal 9
●
through body grounds E12 and E54.
With power and ground supplied, the low beam headlamps illuminate.
High Beam Operation/Flash-to-pass Operation
When the lighting switch is turned to the headlamp ON (2ND) position, high beam (A) or flash-to-pass (C)
position, power is supplied
●
from lighting switch terminal 9
●
to headlamp RH terminal M and
●
to daytime light control unit terminal 8.
Also, when the lighting switch is turned to the headlamp ON (2ND) position, high beam (A) or flash-to-pass (C)
position, power is supplied
●
from lighting switch terminal 6
●
to combination meter terminal 11 for the high beam indicator and

●
to daytime light control unit terminal 5
●
through daytime light control unit terminal 6
●
to headlamp LH terminal M.
Ground is supplied in the same manner as low beam operation.
Ground is supplied to combination meter terminal 10 through body grounds M14 and M68.
With power and ground supplied, the high beam headlamps and high beam indicator illuminate.
DAYTIME LIGHT OPERATION
With the engine running, the lighting switch in the OFF or 1ST position and parking brake released, power is
supplied
●
through daytime light control unit terminal 6
●
to headlamp LH terminal M
●
through headlamp LH terminal E
●
to daytime light control unit terminal 7
●
through daytime light control unit terminal 8
●
to headlamp RH terminal M.
Ground is supplied to headlamp RH terminal E through body grounds E12 and E54.
Because the high beam headlamps are now wired in series, they operate at half illumination.
OPERATION (FOR CANADA)
After starting the engine with the lighting switch in the OFF or parking lamp (1ST) position, the headlamp high
beams automatically turn on. Lighting switch operations other than the above are the same as conventional
light systems.
●
A: High beam position
●
B: Low beam position
●
C: Flash-to-pass position
●
O : Lamp ON
●
X : Lamp OFF
