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 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.
