Driver Airbag Module (DAB) and Clock Spring Repair Procedures

Removal

1. 1
   Disconnect the negative battery cable and wait at least three minutes before starting work.
2. 2
   Remove the airbag module mounting bolts (2EA).

   

3. 3
   Remove the wire clip (C) and disconnect the horn connector (A).

   

4. 4
   Release the connector lock, then disconnect the driver's airbag module connector (B).

   Store the removed airbag module in a clean, dry place with the trim cover facing up.

6. 6
   Disconnect the clock spring and horn connector, then remove the clock spring.

   

Inspection

Driver Airbag (DAB)

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

1. 1
   Inspect the pad cover for dents, cracks, or deformation.
2. 2
   Inspect the airbag module for dents, cracks, or deformation.
3. 3
   Inspect the hooks and connectors for damage, terminals for deformation, and the harness for pinching.
4. 4
   Inspect the airbag inflator housing for dents, cracks, or deformation.

   

5. 5
   Install the airbag module on the steering wheel to check its fit or alignment with the wheel.
6. 6
   If at least one abnormal point is found during the following inspections, replace the clock spring with a new one.
7. 7
   Inspect the connectors and protective tube for damage, and terminals for deformation.

   

Installation

1. 1
   Remove the ignition key from the vehicle.
2. 2
   Disconnect the negative battery cable from the battery and wait at least three minutes before starting work.
3. 3
   Connect the clock spring harness connector and the horn harness connector to the clock spring.
4. 4
   Set the center position by aligning the marks on the clock spring and cover. Make an array mark (xx) by turning the clock spring clockwise until it stops, then turn it counterclockwise 2.0 turns.

   

5. 5
   Install the steering column shroud and steering wheel. (Refer to Steering System - Steering Column and Shaft group)
6. 6
   Connect the driver airbag (DAB) module connector and horn connector, then install the driver airbag (DAB) module to the steering wheel.
7. 7
   Secure the driver's airbag (DAB) with new mounting bolts.

   Tightening torque: 7.8 ~ 10.8 N·m

   

8. 8
   Connect the negative battery cable.
9. 9
   After installing the airbag, check that the system operates correctly:

   A.	Turn the ignition ON; the SRS indicator should illuminate for approximately six seconds, then turn off.

   B.	Check that the horn button operates.
