(2) Disconnect the connector of the wire harness.

(3) Remove the components of airbag assembly.

(4) Remove steering wheel.

3. Removal procedures of clock spring:

(1) Remove the driver airbag assembly (disconnect the connector).

(2) Remove steering wheel gently (see the precautions).

(3) Open the upper closure of the combination switch, locate and

disconnect the connector of wire harness in the lower end.

5. Installation procedures of clock spring:

(1) Pre-Check

Thread the line at the upper end of the clock spring through hole on the body part of the steering

wheel

Connection and fixation of the clock spring and steering wheel

(2) Install the upper hood of the combination switch

(3) Install the steering wheel

(4) Install the airbag assembly components

(5) Connect the negative (-) terminal cable of the battery

(6) Check after installation

6. Removal of steering wheel (see the figure below)

(1) Remove the installation screws from the middle and remove the steering wheel.(Disconnect the horn

connector)

NOTICE:

Due to the tight engagement of the spline and the steering column, it is hard to separate the steering wheel

from the column. Don't try to remove the steering wheel by force (otherwise the clock spring under the

steering wheel will be damaged). The correct way is to turn the nut on the steering column shaft end for

several pitchs and then lift the steering wheel upward.
