2008 GEELY CK Workshop Manual

2664. Check after installation
(1) Slightly rotate the steering wheel left and right, make sure that there is no abnormality or noise. (Driver
airbag module, clock spring)
(2) Turn the ignition switch ON.
(3) The warning light goes on within 6s, and then goes out.
(4) The trouble shall be eliminated if the warning light remains on when the ignition switch is turned on or
after it goes out after 6s.IV. CHECKING1. Driver airbag assembly checking
Check the following items and replace the related components of the airbag assembly if any badness is
found. The old components shall be deployed before scrapping.
(1) Check the hood for pitting, crack, distortion, etc.
(2) Check the joint of the wire harness for damage and the terminal for distortion.
(3) Check the case of the gas generator for pitting, crack and distortion.
(4) Check the installation status of the airbag assembly.
2. Check the clock spring
Check the following items, and replace the clock spring if any badness is found.
(1) Check the joint and protecting tube for damage and the terminal for distortion.
(2) Check the case for damage.
(3) Check and see if the joint terminal at the upper end of the clock spring are in conduction with that at the
lower end.
(4) A thin probe shall be inserted from the back of the yellow connector of the clock spring.NOTICE
If there is pitting, crack or distortion, replace the airbag assembly with new one. The old components of the
airbag shall be deployed before scrapping.
The circuit resistance of the airbag assembly (squib) cannot be measured even with a designated tester.Since there is current flowing in the squib, when a tester is involved in measuring the resistance, sometimesthe airbag is unexpectedly deployed in case of static electricity, leading to serious accident.

267(5) With reference to the figure below, insert thin probes into the current tester to check the conduction of
the terminals.V. KEY POINTS FOR SCRAPPING THE AIRBAG ASSEMBLYThe airbag shall be deployed according to the following procedures before scrapping the airbag assembly or
a vehicle installed with an airbag.
1. Scrapping of an airbag assembly prior to deployment
(1) Deploy inside a vehicle
1Park the vehicle in a flat area NOTICE
Never insert probe directly from the lower end of the connector.
NOTICE
The airbag shall be deployed before being scrapped.
The airbag shall be deployed outside the vehicle before being changed.
The airbag shall be deployed in the vicinity of a smoke detector since smoke will appear when the airbag is
deployed.
When being deployed, the airbag will create much noise. People nearby shall wear noise muffler to close
their ears. Avoid do the job within the residential areas.

2682Disconnect the positive (+) and negative (-) terminal cables from the battery and remove the battery from
the vehicle.
3The airbag assembly shall be deployed according to the following procedures.
(2) Driver airbag assembly
1Remove the knee bolster.
2Remove the connector (yellow) that connecting the lower end of the clock spring with the wire harness
of the instrument panel (see the figure below).
3Tie two 6m plus wire harnesses for deployment to the adaptor wire harness of the airbag, and wrap the
connecting points with insulating tape for insulation. The other ends of the wire harness for deployment
are connected to each other (short circuited). Unexpected deployment resulted from static electricity
shall be prevented.
4From the yellow connector of the clock spring, lead the airbag adapter wire harnesses out of the vehicle
by means of the wire harnesses for deployment (see the figure below).
5To restrain the noise, close all the windows and doors and put on the vehicle cover. NOTICE
Work must be started 60s after the positive (+) and negative (-) terminal cables are detached from battery.NOTICE
Remove the connector of the clock spring from the wire harness of the instrument, the connector will be
short circuited automatically, which can avoid the possible serious accident resulted from the deployment of
the diver airbag assembly due to static electricity.
NOTICE
The glass will likely break up if there is crack. Vehicle covers shall be put on.

2696Try to disconnect at a location far away from the vehicle the connector of the wire harness for deployment
of the driver airbag assembly, connect them with the two terminals of the battery removed from the
vehicle and deploy the airbag (see the figure below).
7The deployed driver airbag assembly shall be scrapped according to the scrapping procedures.
(3) Deploy outside the vehicle
NOTICE:
Keep the airbag over 6m away from a obstacle or person and deploy the airbag in an open flat area.
1Disconnect the positive (+) and negative (-) terminal cables from the battery and remove the battery
from the vehicle.
2The airbag assembly shall be deployed according to the following procedures.
(4) Driver airbag assembly
1Remove the driver airbag assembly from the vehicle.Vehicle CoverWire Harness
for DeploymentNOTICE
Make sure there is no man inside or near the vehicle and then carry out the operations.
After the driver airbag is deployed, the gas generator is of high temperature. Keep it for 30 minutes until it
gets cool for use.
If the driver airbag assembly cannot be deployed, discuss the problem with the local Geely service station.NOTICE
Work must be started 60s after removal of the battery.NOTICE
When the connector is not connected, the terminals of the driver airbag assembly will be short circuited
automatically, preventing the airbag from being deployed unexpectedly. If the airbag is deployed unexpectedly,
the deployed surface should face up. It should be kept on a flat surface without any other items on it.

2702Prepare two 6m plus wire harnesses for deployment, connect the other two ends to avoid unexpected
deployment in case of static electricity (see the figure below).
3Touch the body of the vehicle with hands for static electricity elimination.
NOTICE:
The above-mentioned procedures can prevent the unexpected deployment due to static electricity and shall
therefore be performed strictly.
4Cut off the wire harnesses of the driver airbag assembly and connect them with the two wire harnesses
for deployment, and make sure to wrap up the connecting location with insulating tape for insulation (see
the figure below).
5Install the unused bolts on to the inside bolt of the driver airbag assembly, and tie a thick wire securing the
wheel rim.
6Pass the deployment wire harness of the driver airbag assembly through an old tire with rim, and fix
upwards the driver airbag assembly by means of the wire connected to the bolts, etc (see the figure
below).Wire Harness

272Chapter 8 MK-20 ABS SystemSection 1 ABS DiagnosisI. Check the ABS Warning Light1. Check the ABS Warning Light goes on as the following:
1Turn the ignition switch to ON, the ABS Warning Light goes on for about 1.7 seconds and then goes off.
2If the above condition is not satisfied, it indicates that there is a fault, please check the DTC.
3If the warning light does not light up at all, refer to the Non-DTC fault inspection table.II. The Reading of the information statusAfter connecting the scan meter, turn the ignition switch to¡°ON¡±, select the function menu item 01, press
OK to confirm, the screen will display the following information:
1. ECU drawing number and its version:
ABS MK20 IE
2. Code 01901III. Read and Clear the DTC1. After selecting the "02 Read DTC" in the function menu, it displays the total amount of the fault, if there
is no DTC, then it displays no DTC. Then, press OK button to proceed to next page to review the DTC
and its description. Generally, there is a P or O before the DTC, indicating that it is a Persistent fault or
Occasional fault. Persistent fault remains existing all the time, while the Occasional fault can be cleared
and is only able to reoccur during the driving.
Note:
The reading of the DTC can not be quitted middle way, you can return to the function menu only
after reading all the DTC.
Clear DTC
2. Select function menu item 05, press OK button to clear the DTC, if the DTC can not be cleared, it
indicates that the DTC represent exist all the time, if the saved DTC can be cleared, it indicates that it is
occasional fault can only be detected during the driving.

273IV. DTC Display Method
V. HCU DiagnosisUse the scan meter to diagnose the Hydraulic Control Unit (HCU), select the "3 HCU diagnosis" in the
options and perform the following procedures.
* Perform the above step 2 - 8 test for each wheel in the following order LF RF LR RR.
* If the result of some one of the above steps is different from the normal result, it indicates that the
corresponding element fails the normal operation, please check the corresponding element.
