71-130 WIRING - SYSTEM CIRCUIT DIAGRAM

Description:

• When the ignition switch is ON/ST, the current passes through fuse F32 in the
instrument panel fuse box to pin 7 of the combination switch so as to supply power.
When the circuit outputs from the battery via fuse F8 of the engine compartment
and passes through pin 1 & 2 of front wiper high-speed relay R11 and pin 2 & 1of

low-speed relay R10,Separately to the body control module pins D24、D23 the
front wiper assembly is powered.
• LO position of front wiper switch
When the front wiper switch is in high-speed position, pin 3 of the combinition switch
is grounded and pin 2 outputs signals to pin D3 of ECU C035 in order to provide
a high-speed signal. When the current flows from pin D24 of ECU C035 to pin 2
of front wiper high-speed relay R10 and passes through the coil of relay R10, a
magnetic field is produced and the contact is closed. When the current passes
71
through the contact of relay R10 to pin 3 of the front wiper assembly and is grounded
at pin 4 of the assembly, the front wiper assembly operates at a high speed.

• HI position of front wiper switch
When the front wiper switch is in low-speed position, pin 3 of the combinition switch
is grounded and pin 1 outputs signals to pin D2 of ECU C035 in order to provide
a low-speed signal. When the current flows from pin D23 of ECU C035 to pin 2 of
front wiper low-speed relay R11 and passes through the coil of relay R11, a
magnetic field is produced and the contact is closed. When the current passes
through the contact of relay R11 to pin 5 of the front wiper assembly and is grounded
at pin 4 of the front wiper motor, the front wiper assembly operates at a low speed.

• Washing position of front wiper switch
When the front wiper switch is in washing position, the current inputs from pin 7 of
the combinition switch via pin 6 and outputs to pin 2 of the front washer motor in
order to activate the motor. Meanwhile, the current flows from pin 5 of the
combinition switch to pin E26 of ECU C036 to provide signals for the front wiper.
