(2) 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 

 

1. Permanent magnet DC motor 
2. Worm-gear speed reducer 
3. Wiper motor output shaft 

 

 

 

                    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.

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): 

 

 

1-Water inlet 
2-Impeller blade 
3-Pump body 
4-Water outlet 
5-Permanent magnet DC motor 

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.
