Hyundai Accent (HC): Airbag Module / Driver Airbag (DAB) Module and Clock Spring

- Description

• Driver Air Bag (DAB)DAB is installed in the steering wheel, and electrically connected to the SRSCM via clock spring. It is deployed during frontal impact to protect the driver.

• Clock SpringClock spring delivers actuation signal, generated by the sensors installed in the front and right/left sides of a vehicle, to the inflator (gas generator) of the driver air bag module via internal cable.It also delivers actuation signal of the steering wheel remote control switch and horn to relevant systems via internal cable.

• 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. Driver Air Bag (DAB)
2. Steering Wheel
3. Clock Spring

1.Disconnect the battery negative cable and wait for at least three minutes before beginning work.

• Be careful not to put a tool into a wrong hole. 

5.Remove the steering wheel.(Refer to Steering System - "Steering Wheel")

6.Remove the steering wheel and steering wheel column shround(Refer to Steering System - "Steering Column and Shaft")

7.Disconnect the clock spring connector, then remove the clock spring.

• 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 airbag 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.

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.

1. Set the front tires straight-ahead.

2. Turn the ignition switch OFF.

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

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

5.Factory setting for the clock spring is neutral.

1)If white cable is visible through the product's 10 O' Clock Neutral Check Window, then the spring is at neutral.

2)If white cable is not visible through the product's 10 O' Clock Neutral Check Window, then manually adjust the setting to neutral.

6.Clock spring manual neutral setting procedure.

(1)Turning the clock spring clockwise untill the stop and then 3 revolution counterclockwise.

• Do not rotate until it stops counterclockwise

(2)If white cable is visible through the 10 O' Clock Neutral Check Window, then the spring is set to neutral.

7.Install the steering wheel column shroud and the steering wheel.(Refer to Steering System - "Steering Column and Shaft")

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

• When install the Driver Airbag (DAB) module, Fix the horn wire and DAB inflator wire tightly with wire clip (A).

9.Connect the battery negative cable.

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

• Turn the ignition switch ON; the SRS indicator light should be turned on for about six seconds and then go off.

• Make sure horn button works.
