Driver Airbag Module (DAB) and Clock Spring Repair Procedures

Removal

1. 1
   Before removing the steering wheel, set the front wheels in the straight-ahead position.

   If the steering wheel or front tires are not aligned straight ahead, this may affect the steering wheel rotation amount and may damage the wire inside the clock spring.

2. 2
   Disconnect the battery negative cable.

   After disconnecting the negative battery cable, wait at least thirty seconds.

3. 3
   Release the connector lock, then disconnect the driver airbag module connector (B).

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

4. 4
   Remove the steering wheel. (Refer to Steering System - "Steering Column and Shaft")
5. 5
   Loosen the screws and remove the steering column cover (A).

   

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

   

Inspection

Driver Airbag (DAB)

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

Never attempt to measure the resistance of the airbag module (squib) circuit, even with the specified tester. Measuring the circuit resistance with a tester may cause accidental airbag deployment, which can 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 even one defect is found during the following inspections, the clock spring must be replaced with a new one.
7. 7
   Inspect the connectors and protective tube for damage, and terminals for deformation.

   

Clock Spring

Installation

1. 1
   Before installing the steering wheel, set the front wheels in the straight-ahead position.

   If the steering wheel or front tires are not aligned straight ahead, this may affect the steering wheel rotation amount and may damage the wire inside the clock spring.

2. 2
   Disconnect the battery negative cable.

   After disconnecting the negative battery cable, wait at least thirty seconds.

3. 3
   Center the clock spring before installing it on the steering wheel.

   1. Turn the clock spring clockwise until it stops.

      

   2. Turn the clock spring 3 turns counterclockwise and make sure the arrow aligns with the mark (??). (For a 18-channel heating wire, turn 2 turns counterclockwise.) (Once the arrow is aligned with the mark (??), the clock spring is automatically locked.)

      

4. 4
   Connect the clock spring harness connector and the horn harness connector to the clock spring.
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 module (DAB) connector, then install the driver airbag module (DAB) on the steering wheel.
7. 7
   Connect the negative battery cable.
8. 8
   After installing the airbag, check that the system operates correctly:

   Turn the ignition switch ON; the SRS indicator should illuminate for approximately six seconds before turning off. Make sure the horn operates.
