ABS HECU assy.III. Replace hydraulic control unit1. Press lock catch on joint side, remove wire harness of pump motor.
2. Remove 4 screws as as shown in the figure, the removed old screws
can not be reused.
3. Separate hydraulic control unit HCU from electronic control unit
ECU.
4. Mount new hydraulic control unit HCU onto electronic control unit
ECU.
5. Use new screw to fix ECU onto HCU, tightening moment: 3-4N.m.
6. Insert motor wiring harness, note that lock catch must be in right
position.MK-60 ABS system -
Removal and Installation5-117Schematic diagram for removal of ABS HECU brake oil pipe5. When system is opened, don't use compressed air or move the vehicle.
6. After removing ABS assembly, use appropriate plugs to plug up hydraulic delivery outlets as soon as possible.
Remove other parts that might hinder work.
7. Please use HZY4 brake fluid, do not use mineral oil.
8. Use brake fluid to soak sealing member and Oring, do not use engine oil or brake ointment.
9. After repair, check whether function of routine brake system and ABS brake is reliable and normal or not.
10. Check whether there is any leakage at all Hydraulic couplers.II. Removal of HECU1. Turn off ignition switch and disconnect storage battery minus earth wire.
2. Remove wiring harness plug from ABS HECU assembly.
3. Step down the pedal >60mm, use pedal bracket to fix it, so master cylinder center valve will be turned off, when
system is opened, brake fluid will not flow out from outlet.
4. Put a clean pad under hydraulic controller.
5. Firstly remove brake hard tube (A, B) on HCU connecting with master cylinder, make sign. Plug up the outlet
with a plug immediately.
6. Remove brake pipe (1 - 4) to wheels and make sign. Plug up the outlet with a plug immediately.
7. Remove the screw cap fixing HECU onto the bracket.
8. Remove the entire HECU from bracket.

Flashing way of malfuntion code 17 for O2 sensor (3) Each fault code will blink for three times, interval time is 3s, after blinking for the third times, after an
interval of 3s, next fault code will blink. After blinking of all fault codes is finished, they will blink from begining
again. The following diagram shows engine fault warning lamp blinking mode for oxygen sensor fault code 17.5-127Terminal No. Terminal definition
4 Power supply (-)
7 Bus (signal)
16 Power supply (+)Diagnosis connector Notes: use tester cable to connect handheld tester with diagnostic interface, turn ignition switch to ON position,
operate tester, if tester displays that communication is not possible, the vehicle or tester fails.
Inspection diagnosis
1. Check engine fault warning lamp
(1) When ignition switch is turned to ON position and engine does not run, engine warning lamp on
instrument should illuminate.
(2) When engine runs, engine fault warning lamp should go out. If it still illuminates, diagnostic system
detects system fault or abnormity.
2. Use handheld tester to check diagnostic code
(1) Connect handheld tester according to corresponding pin.
(2) Turn ignition switch to ON position, turn on main switch of handheld tester.
(3) Use handheld tester to detect and check diagnostic code, refer to fault diagnostic code table. (For
operation of handheld tester, see instruction manual of handheld tester)
3. Engine fault warning lamp displays fault code through blinking code, so professional may make fault
judgment in case of emergency.
(1)Turn ignition switch to ON position.
(2) Short signal pin (9#) and negative pole (4#) for more than 2. 5s,then disconnect them,detection fault lamp
on dashboard will blink the faults in fault code according to their occurrence sequence.See from terminal outlet
endConnect in jump way over 2.5s and
disconnect

Chapter 10 On-board Vehicle TelephoneI. Key points for use of Geely hands-free car telephone: 1. Microphone of hands-free car telephone is installed on the back of steering wheel upright column, away from
driver to ensure talking effect. During talking, do not open window, otherwise noisy wind might influence talking
effect.
2. Since there are many kinds of mobile phones in Chinese market, in order to ensure talking effect, please
select interface line corresponding to your mobile phone, otherwise talking effect might be influenced. At present,
Nokia, Motorola, Siemens interface lines are available.
3. To use, insert one end of mobile phone interface line into 8 core RJ 45 stand on automobile panel, connect
the other end to earphone output port of the mobile phone. When mobile phone is not connected, automobile sound
works normally, when mobile phone receive a call, CD becomes quiet automatically, at the same time, loudspeaker
in the vehicle is switched to hands-free telephone output. This hands-free car telephone is provided with response
button at the top of microphone, however, new style of mobile phone does not support manual response function
for the time being, while supports automatic response function, namely it receive the call automatically after
ringing for three times.
4. After talking is finished, automobile sound will return to original state automatically.
5. During daily use, note that contact insertion and withdraw force of mobile phone interface line should not
be too large, so as to avoid damage.
6. Hands-free car telephone has no volume switch, volume of loudspeaker voice may be adjusted by regulating
the volume of handset earphone.II. Circuit diagram5-129On Board Vehicle Telephone-On-board Vehicle TelephonePlease Refer to "MK WIRING DIAGRAM"

Electric A/D switchChapter 11 Rear Parking Radar SystemI. System principle Reversing radar system mainly adopts ultrasonic ranging technology, utilizes piezoelectric property of
transducer (ultrasonic sensor), excites piezo sheet with voltage with frequency of 40KHZ intermittently, this piezo
sheet is then converted from electric energy to mechanical energy and sent out. When emitted sound wave contacts
object, it will reflect weak sound wave energy to transducer according to sound wave reflection principle, i. e.
convert received weak acoustic vibration signal to electrical signal, after signal amplification processing, it is
transmitted to microprocessor to calculate the distance between vehicle and this object and display the distance.
Then microprocessor determines whether to give caution remind for dangerous object according to varying
degrees.II. Circuit diagramPlease Refer to "MK WIRING DIAGRAM"
