Fog/Driving Lamp: Description and Operation

OUTLINE
Power is supplied at all times
- 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)], and
- to front fog lamp relay terminal 3
- through 15 A fuse (No.6, located in the fuse and fusible link box).

When ignition switch is in ON or START position, power is supplied
- to headlamp battery saver control unit terminal 1
- through 10 A fuse [No.30, located in the fuse block (J/B)], and
- 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)].
Ground is supplied to headlamp battery saver control unit terminals 4 and 11.

When Ignition Switch is in ON or START Position
Ground is supplied
- to headlamp RH relay terminal 2 from headlamp battery saver control unit terminal 8.
- through headlamp battery saver control unit terminal 9, and
- through lighting switch, and body grounds E11, E22 and E53.
Headlamp RH relay is then energized.

When Ignition Switch is in OFF or ACC Position
When lighting switch is in 2ND (or 1ST) 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 RH relay terminal 2 from the headlamp battery saver control unit. The headlamp RH relay is then energized.

FOG LAMP OPERATION
The fog lamp switch is built into the combination switch. The lighting switch must be in the 2ND position and LOW ("B") position for fog lamp operation.
With the fog lamp switch in the ON position, ground is supplied
- to fog lamp relay terminal 2
- through the fog lamp switch, lighting switch and body grounds E11, E22 and E53. The fog lamp relay is energized and power is supplied
- from fog lamp relay terminal 5
- to terminal 1 of each fog lamp.
Ground is supplied to terminal 2 of each fog lamp through body grounds E13 and E41. With power and ground supplied, the fog lamps illuminate.

BATTERY SAVER CONTROL
When the ignition switch is turned from ON (or START) to OFF (or ACC) positions while fog lamps 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 1 of headlamp RH relay from headlamp battery saver control unit I terminal 8 is terminated.
Then fog lamps are turned to off.
Fog lamps are turned off when driver or passenger side 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 fog lamps are illuminated.
When the lighting switch is turned from OFF to 1st or 2ND after fog lamps are turned 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
- to headlamp RH relay terminal 2 from headlamp battery saver control unit terminal 8.
Then the fog lamps illuminate again.
