phone GEELY MK 2008 Workshop Manual

Geely “MK” series sedans (JL7132U,JL7132HU,JL7152U,JL7152HU,JL7162U) are brand
new superior models developed by Geely Group who has fully proprietary intellectual property
rights. As a result of the three years of involvements and efforts of the experts from Geely Automo-
bile Research Institute, these sedans reach international leading level in model design, power,
sense of comfort, safety and manufacturing technology while featured in beautiful appearance,
economy, environment protection and safety. The meaning of MK implied that Geely Automobile
has a great development from caterpillar to butterfly. With respect to the power, Geely “MK” series
sedans are equipped with 1.3L, 1.5L, and 1.6L EFI engines developed and manufactured by Geely
itself, and has reached “Chinese III” (Euro III) emission standard.
This manual contains a detailed description of the structures and principles, servicing and adjustment,
removal, assembling technology and matching clearance of the parts of the Geely “MK” sedans
with torque information of the bolts and nuts as well as schematic diagram for special tool operation.
This manual also introduces the transmission control system of the automatic transmission models,
vehicle electric circuits and elaborates ABS system, SRS, BOSCH M7.9.7 electronic control fuel
injection and ignition system, rear parking radar, sound, air conditioning and onboard hands-free
phone system. You can refer to this manual for the information about the regular maintenance,
servicing, adjustment, troubleshooting, removal and installation procedure, specific operations of
the “MK” sedans.
This manual covers the matching relation among the engine assembly, transmission assembly and
the vehicle, but does not have the further description of the structures and principles of the engine
and transmission assemblies and their servicing process. You can refer to the service manuals
solely prepared for engine assembly and transmission assembly for these information.
All information in this manual is based on the latest products released at the time of publication of
this manual. However, the specifications and procedures may need to be modified, and the subse-
quent change will be revealed in later versions.
This manual is prepared by Geely Automobile Research Institute under the assistance of technical
staff from Zhejiang Geely Automobile Co., Ltd and Geely International Corporation. Readers
discovering during the use of this manual the errors and careless omissions due to limited skills of
the preparers and tight schedule are encouraged and pled to contact Geely International in time for
our timely correction of the mistakes.ForewordGeely International Corporation

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"

III. Troubleshooting:1.Whether power supply is normal or not.
2. Increase mobile phone output volume.
3. Confirm whether mobile phone interface line is correct, (replace
with new mobile phone interface line).
4. When mobile phone works, confirm whether there is relay
closing sound in hands-free telephone box.
5. If there is relay closing sound, check whether anything is wrong
with socket drop-out line.
Adjust mobile phone output volume.
Check receiving signal of mobile phone. No. Symptom Possible cause

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"
