(3) Remove the steering column cover and disconnect the connector of wire harness in the lower end.
(4) Remove clock spring.
Installation procedures of the driver airbag assembly
(1) Pre-Check

1- Install steering wheel

2- Connect the wire harness

3- Install driver airbag assembly

4- Screw up the installation screws of the two sides
(2) Connection of the negative (-) terminal of the battery
(3) Check after installation.
Installation procedures of clock spring:
(1) Pre-Check

(3) Check after installation5-66Key points for installation
(1)Pre-Check
a. The new airbag or clock spring shall be checked before being installed.SRS (Supplemental Restraint System)-SRS-General InformationNotice
Use scanner to do adiagnossis of airbag circnit, not to break down.
Keep the removed driver airbag assembly upside down in a clean and dry place.Notice
Keep the removed clock sprint in a clean and dry place.fig.2Installation nutRemoval of steering wheel (see the figure 2)
(1) Remove the installation screws from the middle and remove
the steering wheel.(Disconnect the horn connector)

5-68Notice
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, sometimes
the airbag is unexpectedly deployed in case of static electricity, leading to serious accident.
(2) Check the clock spring
Check the following items, and replace the clock spring if any badness is found.
a. Check the connector and protecting tube for damage and the terminal for distortion.
b. Check the case for damage.
c. Check and see if the joint terminal at the upper end of the clock spring are in conduction with that at the
lower end.
d. A thin probe shall be inserted from the back of the yellow connector of the clock spring.
e. With reference to the figure below, insert thin probes into the current tester to check the conduction of the
terminals.VIII. Key points for scrapping the airbag assembly The 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 deploymentNotice
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.
Deploy inside a vehicle
1) Park the vehicle in a flat area
2) Disconnect the positive (+) and negative (-) terminal cables from the battery and remove the battery from
the vehicle.SRS (Supplemental Restraint System)-
SRS-General Information a. Check the cover for pitting, crack and distortion.
b. Check the connector of the wire harness for damage and the terminal for distortion.
c. Check the case of the gas generator for pitting, crack and distortion.
d. Check the installation status of the airbag assembly. 2. Checking
(1) 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.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.

diagnosis" , proceed according to the following steps.MK-60 ABS system -
ABS Diagnosis5-99I. Check ABS warning lamp1. Check whether ABS warning lamp illuminates in the following way
a. Ignition switch turns to ON, ABS warning lamp illuminates for approximately 1.7s then goes out.
b. If it is not the above-mentioned case, it shows that there is fault, please check fault code.
c. If warning lamp does not illuminate at all, refer to trouble check list without fault code.II. Reading of information state After power on fault diagnosis instrument, turn ignition switch to "ON " position, select function menu item
01, press OK for confirmation, the screen will display the following status information
1. E. g. ECU drawing number and version number:
ABS MK60 IE
2. Code 040907III. Read and eliminate fault code1. After select "02 read fault code" in function selection menu, firstly display total number of fault, if there is no
fault code, display no fault code. Now, press OK key to turn page, look down for fault code and its description.
There is generally P or O before fault code, which represents that this is a persistent fault or a occasional fault.
Persistent fault always exists, while occasional fault may be eliminated, only when run on real vehicle, might it
appear again.
Note:
Read fault code function can not be exited in midway, only after all fault codes are turned over, could it return
to function menu.
Eliminate fault code
2. In function selection function menu 05, press OK key to eliminate fault code, if fault code cannot be eliminated,
it shows that this is a occasional fault, could be detected again only when the vehicle is actually running.IV. Display mode of malfunction codeDisplay code
