WIRING - SYSTEM CIRCUIT DIAGRAM 71-77

Description:

• Low beam control
The current of the battery flows from the low beam relay R2 in the engine
compartment fuse box and provides supply power. When the combination switch
is in the low beam position, the body control module connector C035 pin D15 is
grounded, the low beam relay R2 coil generates a magnetic field after electrified,
and the contact is closed. Then the current flows from the low beam relay R2 pin
5 and divided into two paths: one is from fuse F22 to the front right combination
lamp pin 2, through the low beam filament and pin 5 and grounded, the low beam
starts to work; The other is from fuse F21 to the front left combination lamp pin 2,
through the low beam filament and pin 5 and grounded, the low beam starts to
work.

• High beam control
71
When the combination switch is in the high beam position, the body control module
connector C035 pin D14 is grounded, the high beam relay R6 coil generates a
magnetic field after electrified, and the contact is closed. Then the current flows
from high beam relay R6 pin 5, through the fuse F27, output to the front right
combination lamp and front left combination lamp pin 1 respectively, then through
the high beam filament and grounded via pin 5, the high beam starts to work.
• Passing lamp control

When the combination switch is in the overtaking light position, the body control
module connector C036 pin E8 is grounded, the high beam relay R6 coil generates
a magnetic field after beeing electrified, and the contact is closed.Then the current
flows from high beam relay R6 pin 5, through the fuse F27, output to the front right
combination lamp and front left combination lamp pin 1 respectively, then through
the high beam filament and grounded via pin 5, the high beam starts to work.
