Connect

the

diode-testing

light

to

high-pressure switch and
increase the engine speed
slowly.

When

the

oil

pressure

reaches

160-200KPa,

the

light-emitting diode should
be lighted. If it is not
lighted, then it indicates
that the high pressure
switch is faulty; further
increase the engine speed
up to 2000r/min, then the
oil pressure should reach at
least 200KPa. Otherwise it
indicates

that

the

lubricating

system

is

faulty.
Upon the above inspection,
if the lubricating system
and lubricating oil pressure
switch are both normal,
but the warning lamp
keeps on indicating that
the malfunction is still
present, and it should
inspect

the

circuit

malfunction according to
the circuit diagram.
Pay

attention

when

carrying

out

the

inspection:

for

low

pressure warning switch
circuit, the warning lamp
will be lighted when there
is a short circuit to ground,
so it should emphasize on
inspecting to see whether
there is any grounding;
while for high pressure
warning switch circuit, the
warning lamp will be
lighted when there is an
open circuit as well as
when the engine speed is
over 2000r/min, so it
should

emphasize

on

inspecting to see whether
there is any open circuit.

Coolant

warning lamp

is always on.

The warning

lamp for

coolant is

always on

while driving,

whatever it’s

in cold

condition or

hot condition.

(1) Coolant level
in storage tank is
too low.
(2)

Malfunction

of coolant level
switch.
(3)

Malfunction

of warning switch
for

coolant

temperature.
(4) Warning lamp
circuit

is

grounded.

(1) Inspect to see whether
the

engine

coolant

temperature is actually too
high and the level of the
storage tank is too low.
(2) If all the above
inspection are normal, then
pull out the connector of
the storage tank level
switch. If the warning
lamp is off, it indicates that
the liquid level switch is
faulty.
(3) If the warning lamp is
still on, then connect the
connector of coolant level
switch and pull out the
connector of the coolant
temperature

warning

switch. If the warning
lamp is off, it indicates that
the warning switch of
coolant

temperature

is

faulty; If the warning lamp
is still on, it indicates that
the circuit is grounded
somewhere.

Brake

warning lamp

is always on.

Brake

warning lamp

is still on even

if the hand

brake is

released.

(1) Brake oil level
is too low.
(2)

Malfunction

of brake oil level
switch.
(3)

Malfunction

of

hand

brake

switch.
(4) Warning lamp
circuit is faulty.

(1) Inspect to see whether
the brake oil level is too
low or not.
(2) If the oil level is
normal, then pull out the
connector of brake oil
level

switch.

If

the

warning lamp is off, it
indicates that the brake oil
level switch is faulty.
(3) If the warning lamp is
still on, pull out the
connector of the brake
switch. If the warning
lamp is off, it indicates that
the brake switch is faulty;
If the warning lamp is still
on, it indicates that the
circuit

is

grounded

somewhere.

ELECTRIC WIPER AND WINDSHIELD WASHER SYSTEM

SYSTEM DESCRIPTION

The wiper is mainly consisted of the wiper motor assembly, the three-linkage mechanism,
and the pendulum rod and wiper blade with the tri-directional flexible ball joint. See figure
(wiper-1). The wiper motor is shown in figure (wiper-2).

Wiper motor（wiper-2）

The wiper motor is a speed reducer comprised of a mini permanent magnetic DC motor and a
worm-gear. In order to ensure that the pendulum rod and wiper blade could be positioned
under and parallel with low end of the front window each time after it has stopped. An
automatic stop conducting strip is installed on the back of the worm output shaft of the speed
reducer and 3 conducting contacts that contact with the conducting strip are installed on the
rear cover of the speed reducer. The strip and the contacts jointly perform the automatic stop
function together with the contact of the 0 position of wiper switch.

1. Permanent magnet DC motor

2. Worm-gear speed reducer

3. Wiper motor output shaft

The washer is consisted of 5 parts which including a mini permanent magnet DC motor,
centrifugal water pump, nozzle, liquid storage container and water pipe. The motor and water
pump make up the assembly of the washer motor and the water pump as shown in figure
(Wiper-3):

Washer Motor（wiper-3)

As shown in figure (wiper-4), this assembly is installed on the liquid storage container and
make up the washer assembly together with the liquid storage container. The washer
assembly is installed on the left-hand impeller blade and the capacity of the liquid storage
container is 5.1 L.
