Used Tire Without
hub
Deployed HarnessDeployed Harness h. Try to disconnect at a location far away from the vehicle the
connector of the wire harness for deployment of the driver
airbag assembly, connect with the two terminals of the
battery removed from the vehicle and deploy the airbag
(see the figure on the right). g. Put three used tires without hubs onto the tire used to fix the
driver airbag assembly (see the figure on the right).
i. The deployed driver airbag assembly shall be scrapped according to the scrapping procedures.Notice
Make sure to deploy the driver airbag assembly when there is no person close by.
After the driver airbag is deployed, the gas generator is of high temperature. Keep it for over 30 minutes
until it gets cool for use.
If the driver airbag can't be deployed, please contact the Geely service station for help.5-71SRS (Supplemental Restraint System)-

firstly confirm whether voltage of storage battery is normal, when conduct motor drive test, vehicle must be in idle
state.MK-60 ABS system -ABS System Check5-103Fault code is 01276 1
[Description ] When vehicle speed exceeds 20 km/h, ABS ECU monitors that
motor can not work normally, it will record this fault code
[Prompt ] When this fault appears, wiring harness connection between motor
and ECU may get loose. Use hydraulic pressure unit functional
testing of fault diagnosis instrument to drive motor for this test.Possible cause

Power supply is discon-
nected or earthed

Motor wiring harness gets
loose

Motor is damaged
Pull out motor wiring harness plug, connect
battery power source directly to motor plug, see
whether motor works or not?
Check safety wire and ABS ECU joint
Connect motor wiring harness
Turn ignition switch to ON position
Eliminate fault code
Use fault diagnosis instrument to conduct
hydraulic control unit diagnosis
Whether fault recurs
Refer to "key points of occasional fault
repair"

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.
