For Canada

System Description
The headlamp system for Canada vehicles is equipped with 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 BCM.

Power is supplied at all times
- to headlamp relay-1 terminal 2,
- to headlamp relay-1 terminal 3
- through 20 A fuse [No. 57, located in the fuse, fusible link and relay block (J/B)],
- to headlamp relay-1 terminal 7
- through 20 A fuse [No. 55, located in the fuse, fusible link and relay block (J/B)],
- to headlamp relay-2 terminals 1 and 3
- through 15 A fuse (No. 73, located in the fuse, fusible link and relay box),
- to headlamp battery saver control unit terminal 7
- through 10 A fuse [No. 6, located in the fuse block (J/B) No. 1], and
- to BCM terminal 105
- through 10 A fuse [No. 3, located in the fuse block (J/B) No. 1].

When the ignition switch is in the ON or START position, power is also supplied
- to daytime light control unit terminal 3
- through 10 A fuse (No. 82, located in the fuse, fusible link and relay box), and
- to headlamp battery saver control unit terminal 1 and
- to BCM terminal 68
- through 10 A fuse [No. 1, located in the fuse block (J/B) No. 1].

When the ignition switch is in the ACC or ON position, power is supplied
- to BCM terminal 60
- through 10 A fuse [No. 21, located in the fuse block (J/B) No. 1].

When the ignition switch is in the START position, power is supplied
- to daytime light control unit terminal 2
- through 10 A fuse [No. 14, located in the fuse block (J/B) No. 1].

Ground is supplied
- to daytime light control unit terminal 16
- through body grounds E42 and E62,
- to headlamp battery saver control unit terminals 4 and 11
- through body grounds M25 and M115, and
- to BCM terminals 56 and 113
- through body grounds M24 and M114.

HEADLAMP OPERATION

Power Supply to Low Beam and High Beam
When lighting switch is in 2ND or PASS position, ground is supplied
- to headlamp relay-1 terminal 1
- to headlamp relay-2 terminal 2
- from headlamp battery saver control unit terminals 2 and 8
- through headlamp battery saver control unit terminals 3 and 9
- through lighting switch terminals 12 and 8
- through body grounds M25 and M115.

Headlamp relays are energized and then power is supplied to headlamps.

Low Beam Operation
When the lighting switch is turned to 2ND position and placed in LOW positions, power is supplied
- from terminals 5 and 6 of headlamp relay-1
- to terminal 3 of each headlamp

Ground is supplied
- to terminal 4 of each headlamp
- through body grounds E24 and E42.

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 position and placed in HIGH position or PASS position, power is supplied
- from terminal 5 of headlamp relay-2
- to terminals 4 and 5 of daytime light control unit and
- to combination meter terminal 9 for the HIGH BEAM indicator.

Ground is supplied
- to headlamp LH terminal 2
- through daytime light control unit terminals 10 and 13, and
- to combination meter terminal 10 for the HIGH BEAM indicator
- through lighting switch terminals 9 and 8
- through body grounds M25 and M115, and
- to headlamp RH terminal 2
- through daytime light control unit terminals 9 and 14
- through lighting switch terminals 6 and 5
- through body grounds M25 and M115.

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 BCM terminal 135.

After counting 45 seconds by the RAP signal from the BCM to headlamp battery saver control unit, the ground supply to both terminal 1 of headlamp relay-1 and terminal 2 of headlamp relay-2 from headlamp battery saver control unit terminals 2 and 8 is terminated.

Then headlamps are turned off.

The headlamps are turned off when front door (driver or passenger side) 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 supplied
- to headlamp battery saver control unit terminals 5 and 13 from lighting switch terminal 11, and then
- to both terminal 1 of headlamp relay-1 and terminal 2 of headlamp relay-2 from headlamp battery saver control unit terminals 2 and 8
- through headlamp battery saver control unit terminals 3 and 9, and
- through lighting switch terminal 12.

Then headlamps illuminate again.

AUTO LIGHT OPERATION
For auto light operation, refer to "AUTO LIGHT OPERATION" in "HEADLAMP (USA)".

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 headlamp RH terminal 1
- through headlamp RH terminal 2
- to daytime light control unit terminal 9
- through daytime light control unit terminal 6
- to headlamp LH terminal 1
- through headlamp LH terminal 2
- to daytime light control unit terminal 10.

Ground is supplied
- to daytime light control unit terminal 16
- through body grounds E42 and E62.

Because the high beam headlamps are now wired in series, they operate at half illumination.

Operation:

OPERATION
After starting the engine with the lighting switch in the "OFF" or "1ST" position, the headlamp high beam automatically turns on. Lighting switch operations other than the above are the same as conventional light systems.
