System Description
NHEL0207
The parking, license and tail lamp operation is controlled by the lighting switch which is built into the combi-
nation switch and smart entrance control unit. The battery saver system is controlled by the smart entrance
control unit.
Power is supplied at all times
I
to tail lamp relay terminals 1 and 3
I
through 10A fuse (No. 60, located in the fuse and fusible link box), and
I
to smart entrance control unit terminal 49
I
through 10A fuse [No. 13, located in the fuse block (J/B)].
When ignition switch is in ON or START position, power is supplied
I
to smart entrance control unit terminal 27
I
through 10A fuse [No. 1, located in the fuse block (J/B)].
When the ignition switch is in the ACC or ON position, power is supplied
I
to smart entrance control unit terminal 26
I
through 10A fuse [No. 1, located in the fuse block (J/B)].
Ground is supplied to smart entrance control unit terminals 43 and 64.
LIGHTING OPERATION BY LIGHTING SWITCH
NHEL0207S01
When lighting switch is in 1ST (or 2ND) position, ground is supplied
I
to tail lamp relay terminal 2 from smart entrance control unit terminals 19 and 57
I
through smart entrance control unit terminals 20 and 58, and
I
through lighting switch and body grounds E11, E22 and E53.
Tail lamp relay is then energized and the parking, license, side marker and tail lamps illuminate.
LIGHTING OPERATION BY AUTO LIGHT CONTROL SYSTEM
NHEL0207S03
When lighting switch is in AUTO position, ground is supplied
I
to tail lamp relay terminal 2 from smart entrance control unit terminals 19 and 57
I
through smart entrance control unit terminals 43 and 64, and
I
to body grounds E11, E22 and E53.
Tail lamp relay is then energized and the parking, license, side marker and tail lamps illuminate.
BATTERY SAVER CONTROL
NHEL0207S02
Parking, license, side marker and tail lamps will remain on for a short while after the ignition switch is turned
ON (or START) from OFF (or ACC).
Continuity between terminals 19 and 20, and between terminals 57 and 58 of smart entrance control unit will
be disturbed after 45 seconds, then the headlamps will be turned off.
Then the parking, license, side marker and tail lamps are turned off.
The parking, license, side marker and tail 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 parking, license, side marker and tail lamps are illuminated.
When the lighting switch is turned from OFF to 1ST (or 2ND) after the parking, license, side marker and tail
lamps are turned off by the battery saver control, ground is supplied.
I
to smart entrance control unit terminals 20 and 58 from lighting switch terminal 11, and
