13、ECU coding

Coding the new ECU after replacing/ repairing ECU or HECU. Otherwise ABS

warning light cannot work normally.

Coding ECU with instrument, go to steps as follows：

将故障诊断仪与诊断插座连接

选择[万用 OBD-16]诊断接头

在功能项目中选择“控制单元编码”

屏幕上显示“请输入新的编码_ _ _ _ _”

（ 此车的编码为：01901）

按“确认”键后，屏幕上即显示

1J0907379 P ABS 20 IE CAN

001

Coding: 01901

WSC: 000001

编码完成，退出

Screen display “ please input new coding_ _

_ _ _ _” (The coding for this car: 01901)

Press“ok ” key, screen displays

Select “ control unit coding

”

Selection [Versatile OBD-16]diagnosis socket

Connect diagnosis instrument and diagnosis

socket

End coding and

quit

14、Charging and evacuating
1. Wet HCU

If HCU is wet type, charge and evacuate according to conventional brake system

after replacing HCU.
2. Dry HECU

If HCU is dry type, besides charging and evacuating according to conventional

brake system after replacing HCU, it should be operated the second loop of HECU
with instrument.

Appendix 1

Question and answer for ABS

1. What is ABS?

ABS is abbreviation for Anti-lock Brake System. ABS ensures good brake
stability and steering on various roads to get best brake distance.

2. Why need ABS?

When braking, front wheel will lock up to lose steering ability; while rear
wheel will lock up to run to a side or slide. ABS will help you to control
vehicle and to steer clear of barrier during braking.

3. How to distinguish if your vehicle equipped with ABS?

Firstly, you could observe if the ABS warning light on instrument cluster or
on switchboard is on in short period. Secondly, you may ask your dealer.

4. How does ABS work?

The ECU in ABS will adjust the pressure on each wheel brake through solenoid
according to VSS signal. It just likes a good driver but with much faster
reflection.

5. How to distinguish ABS is working?

When ABS is working, you will feel the vibration of brake pedal, and hear the
noise of hydraulic controller is working. Keep step down on the pedal. At the
most situations, the brake distance for vehicle with ABS is shorter than the
vehicle without ABS, especially on icy road or wet road. Please remember to
turn steering wheel to steer clear of barrier.

6. What should do if ABS is fault?

Once ABS is fault, ABS warning light will be on. ABS will not work, but the
conventional brake system is working. So you could brake vehicle as usual way.

7. When will ABS light be on?

ABS light will be on for about 1.7s after engine starting, then turns off.
Only ABS is fault, ABS light will be on again. So once ABS light is on, go
to service station at once. Don’t try to repair ABS by yourself.

Appendix 2

How to use ABS?

Always step down brake pedal to keep enough and lasting brake force for ABS.

56

Keep enough brake distance. When driving on good road, keep at least 3 s of

braking from front vehicle. When driving on bad road, keep more time for
braking.

Practice ABS braking before driving. Get ready for pedal’s vibration when

ABS is working. Parking place and square are the best place for practicing.

Read owner’s manual carefully to better understand each instruction offered

by manufacture.

Don’t drive vehicle with ABS at random. It’s dangerous to turn sharp or steer

hard.

Don’t step down brake pedal repeatedly. When driving vehicle with ABS, it

will cause ABS on and off frequently, which will decrease the ability of braking
and increase braking distance. In fact, ABS will control brake ability
automatically.

Don’t forget to turn steering wheel. ABS supply steering control ability for

driver, but itself cannot steer automatically.

Don’t be afraid of the noise of hydraulic system’s working and pedal

vibration. The noise is normal and means ABS is working.
