For Canada

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.
And battery saver system is controlled by the headlamp battery saver control unit and smart entrance control unit.
Power is supplied at all times
- to headlamp LH relay terminals 1 and 5
- through 15 A fuse (No.68, located in the fuse and fusible link box), and
- to headlamp RH relay terminals 1 and 5
- through 15 A fuse (No.69, located in the fuse and fusible link box), and
- to headlamp battery saver control unit terminal 7
- through 10 A fuse [No.12, located in the fuse block (J/B)].
Ground is supplied
-to daytime light control unit terminal 16 and
-to headlamp battery saver control unit terminals 4 and 11
When the ignition switch is in the ON or START position, power is also supplied
- to daytime light control unit terminal 3,
- to headlamp battery saver control unit terminal 10, and
- to smart entrance control unit terminal 33
- through 10 A fuse [No.10, located in the fuse block (J/B)], and
- to headlamp battery saver control unit terminal 1
- through 10 A fuse [No.30, located in the fuse block (J/B)).
When the ignition switch is in the START position, power is supplied
- to daytime light control unit terminal 2
- through 10 A fuse [No.21, located in the fuse block (J/B)].

HEADLAMP OPERATION
When Ignition Switch is in ON or START Position

Ground is supplied
- to headlamp LH relay terminal 2 from headlamp battery saver control unit terminal 2
- through headlamp battery saver control unit terminal 3, and
- to lighting switch terminal 12, and
- to headlamp RH relay terminal 1 from headlamp battery saver control unit terminal 8
- through headlamp battery saver control unit terminal 9, and
- to lighting switch terminal 12.
Headlamp relays (LH and RH) are then energized.

When Ignition Switch is in OFF or ACC Position
When lighting switch is in 1ST (or 2ND) position, ground is supplied
- to headlamp battery saver control unit terminals 5 and 13
- from lighting switch terminal 11.
And then, ground is also supplied to headlamp LH and RH relays terminal 2 from headlamp battery saver control unit. Headlamp relays (LH and RH) are then energized.

Low Beam Operation
When the lighting switch is turned to 2ND and LOW ("B") positions, ground is supplied
- to terminal 2 of the headlamp LH
- through daytime light control unit terminals 11 and 15
- through lighting switch terminals 10 and 8
- through body grounds E11, E22 and E53.
Ground is also supplied
- to terminal 2 of the headlamp RH
- through daytime light control unit terminals 8 and 12
- through lighting switch terminals 7 and 5
- through body grounds E11, E22 and E53.
With power and ground supplied, the low beam headlamps illuminate.

HIGH BEAM OPERATION / FLASH-TO-PASS OPERATION
When the lighting switch is turned to 2ND and HIGH ("A") or PASS ("C") positions, ground is supplied
- to terminal 1 of LH headlamp
- through daytime light control unit terminals 10 and 14, and
- to combination meter terminal 27 for the HIGH BEAM indicator
- through lighting switch terminals 9 and 8
- through body grounds E11, E22 and E53.
Ground is also supplied
- to terminal 1 of RH headlamp
- through daytime light control unit terminals 9 and 13
- through lighting switch terminals 6 and 5
- through body grounds E11, E22 and E53.
With power and ground supplied, the high beam headlamps and HIGH BEAM indicator illuminate.

BATTERY SAVER CONTROL
When the ignition switch is turned from ON (or START) to OFF (or ACC) positions while headlamps are illuminated, The RAP signal is supplied to terminal 10 of the headlamp battery saver control unit from smart entrance control unit terminal 5.
After counting 45 seconds by the RAP signal from the smart entrance control unit to headlamp battery saver control unit, the ground supply to terminal 2 of headlamp LH and RH relays from headlamp battery saver control unit terminals 2 and 8 is terminated.
Then headlamps are turned off.
The headlamps are turned off when LH or RH door is opened even if 45 seconds have not passed after the ignition switch is turned from ON (or START) to OFF (or ACC) positions while headlamps are illuminated. When the lighting switch is turned from OFF to 2ND after headlamps are turned to off by the battery saver control, ground is supply
- to headlamp battery saver control unit terminals 5 and 13 from lighting switch terminal 11, and
- to headlamp LH and RH relays terminal 2 from headlamp battery saver control unit terminals 2 and 8.
Then headlamps illuminate again.

AUTO LIGHT OPERATION
For auto light operation, refer to "HEADLAMP".

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 7
- to terminal 3 of RH headlamp
- through terminal 1 of RH headlamp
- to daytime light control unit terminal 9
- through daytime light control unit terminal 6
- to terminal 3 of LH headlamp.
Ground is supplied to terminal 1 of LH headlamp.
- through daytime light control unit terminals 10 and 16
- through body grounds E11, E22 and E53.
Because the high beam headlamps are now wired in series, they operate at half illumination.
