Hyundai i30 (PD) 2018-2025 Service Manual / Restraint / Airbag Module / Driver Airbag (DAB) Module and Clock Spring

Components and components location

Components

1. Driver Air Bag (DAB)
2. Steering Wheel

3. Clock Spring

Description and operation

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 Spring

Clock 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.

Repair procedures

Removal

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

Remove the driver airbag module.

[Without Paddle Shift]

–	Putting in a flat tool (Ø5mm) into the guide hole and then press the pin.

[With Paddle Shift]

–	Putting in a flat tool (Ø5mm) into the guide hole (A) and then rotate it.

•	After inserting the tool, press the DAB fixed pin in the direction of the arrow as illustration below.

Disconnect the air bag connector (A) and horn connector (B).

•	The removed airbag module should be stored in a clean, dry place with the pad cover facing up.

4.	Remove the steering wheel and steering wheel column shroud (A). (Refer to Steering System - "Steering Column and Shaft")

5.	Disconnect the clock spring (A) and horn connector, then remove the clock spring.

Inspection

Driver Airbag (DAB)

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

•	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.

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.	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.

Assemble the neutral state clock spring.

[Clock Spring Manual Neutral Setting Procedure]

1)	Turn the clock spring clockwise until it stops.

2)	When it comes to a stop, turn it counter-clockwise and align the neutral mark ( ▶◀ ).

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

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).

7.	Connect the battery negative cable.

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.
