Kia Sportage: Driver Airbag (DAB) Module and Clock Spring

Description and Operation

 Description

Driver Airbag (DAB) is installed in the steering wheel and electrically connected to SRSCM via the clock spring. It protects the driver by deploying the air bag when frontal crash occurs. The SRSCM determines deployment of the Driver Airbag (DAB).

CAUTION

Never attempt to measure the circuit resistance of the air bag module (squib) even if you are using the specified tester. If the circuit resistance is measured with a tester, accidental airbag deployment will result in serious personal injury.

 Inspection

Driver Airbag (DAB)

If any improper parts are found during the following inspection, replace the airbag module with a new one.

CAUTION

Never attempt to measure the circuit resistance of the airbag module (squib) even if you are using the specified tester. If the circuit resistance is measured with a tester, accidental airbag deployment will result in serious personal injury.

1. Check pad cover for dents, cracks or deformities.

2. Check the air bag module for denting, cracking or deformation.

3. Check hooks and connectors for damage, terminals for deformities, and harness for binds.

4. Check airbag inflator case for dents, cracks or deformities.

5. Install the airbag module to the steering wheel to check for fit or alignment with the wheel.

Clock Spring

1. If, as a result of the following checks, even one abnormal point is discovered, replace the clock spring with a new one.

2. Check connectors and protective tube for damage, and terminals for deformities.

Installation

1. Remove the ignition key from the vehicle.

2. Disconnect the battery negative cable from battery and wait for at least thee minutes before beginning work.

3. Connect the clock spring harness connector and horn harness connector to the clock spring.

4. Set the center position by setting the marks between the clock spring and the cover into line. Make an array the mark ( ) by turning the clock spring clockwise to the stop and then 2.0 revolutions counterclockwise.

5. Install the steering wheel column cover and the steering wheel. (Refer to the Steering System group - Steering Column and Shaft)

6. Connect the Driver Airbag (DAB) module connector and then install the Driver Airbag (DAB) module on the steering wheel.

7. Secure the Driver Airbag (DAB) with the new mounting bolts.

Tightening torque: 7.8 ~ 10.8 N.m (0.8 ~ 1.1 kgf.m, 5.1 ~ 8.0 lb-ft)

8. Connect the battery negative cable.

9. After installing the airbag, confirm proper system operation:

1. Turn the ignition switch ON: the SRS indicator light should be turned on for about six seconds and then go off.
2. Make sure horn button works.
