In low-speed operation

Check the front brusher motor
Connect the anode lead to the terminal 2 (1) from accumulator, and

the cathode lead to terminal 3, at this time, the front wiper motor

should be in low-speed operation, otherwise change the front

brusher motor.

In high-speed operation

 Connect the anode lead to the terminal 1(2) from the accumulator,

and cathode lead to terminal 3, in such condition, the front wiper

motor should be in high-speed operation.

In case the operation fails to meet the requirement, change the front

wiper motor.

in operation

stop running at the stop position

a.

Run the front wiper motor at low speed and stop it at any

positions excluding the stop position by disconnect the

anode lead from the terminal 2 (1).

b.

Connect the terminals 2 and 5.\

c.

Connect the anode lead to the terminal 6 (4) from the

accumulator, and the cathode lead to terminal 3, check

whether the wiper motor parks at the stop position after

it running for another time, if the requirement is not

satisfied, change the front brusher motor.

Remark: items in parenthesis is for Dr and SF.

Rear brusher motor inspection

Connect the anode lead to the terminal 3 from the accumulator, and

the cathode lead to terminal 4, at this time, the wiper motor will be

in normal operation, disconnect the terminal 3, the rear wiper motor

should stop running at any position excluding the stop position.

Connect the anode lead to terminal 3 from the accumulator, and

cathode lead with terminal 4, at this time, the wiper motor should

be in normal operation, under such condition, disconnect the

terminal 3, which is connected with terminal 1, and the anode lead

is connected to the terminal 2, in such case, the rear wiper motor

should stop running at the stop position.

In case the operation fails to satisfy the specified requirement,

change the rear wiper motor.

Inspection on Washer Motor

Connect the anode lead to the terminal 1 from the accumulator, and

the cathode lead to the terminal 2, at this time the washer motor

should be in normal operation.

Notice: this test should be finished rapidly (within 20 seconds).

In case the operation fails to meet the specified requirement, change

the washer motor.

Definition for connecting wire of central control lock

1.

Y/V

Connect the power

to the cell anode on vehicle, in front of which a fuse of 15 A should be set, and

anode of 12V

when the motor is started, the voltage should not less than 10V

2.

B1

Unlocking output of

the locking wire of the CCL actuator, and the grounding wire at the normally

 central control lock:

closed contact inside the relay will contact with the normally opening contact at

 the common spots inside relay when unlocking with REMOTE CONTROLLER

 or manually, the wire will output 12 V voltage.

3.

LG

locking signal of

The CCL locking signal is connected to the unlocking wire of actuator of CCL,

 central control lock

and the normally closed contact in the interior relay is grounding wire, which will

output 12 V voltage when unlocking with REMOTE CONTROLLER or manually

and the common spots of relay contacting the normally opening contact.

4.

non-connection

There is no wire connected at present

5.

G/R

Right turn lamp

Connected to the anode wire of the right turn lamp on the vehicle, and it will output

12 V voltage in operation.

6.

G/Y

Left turn lamp

Connected to the anode wire of left turn lamp on the vehicle, and it will output

12 V voltage when in operation

7.

Br

Negative input of

Which is connected to the door switch and it is grounding when the  door is

door switch

opened (the indoor lamp will light)

8.

GD

ON power check cable

Connected to the ON wire of the locking door( there will be 12 v voltage when

rotating the key at 

ON

 position.

9.

Non-connection

This wire is not connected temporarily

10. GD/B Lock head lamp output

There will be 12 V voltage outputted in this wire when opening the door, and will

be powered off (no output) ten seconds later after the door is closed

12. Y/B

Locking signal

Connected to the locking signal wire of CCL at the left front door, and connect

to the grounding wire when in operation.

13. B

Power cathode

Connect to the body (grounding wire) it should be as short as possible, because

the overlong wire will produce the interference source.
