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 deploymentcould result in serious personal injury.
Check the pad cover for dents, cracks or deformities.
Check the airbag module for denting, cracking or deformation.
Check hooks and connectors for damage, terminals for deformities, and harness for binds.
Check the airbag inflator case for dents, cracks or deformities.
Install the airbag module to the steering wheel to check its fit.
If, as a result of the next check, even one abnormal point is discovered, replace the clock spring with a new one.
Check connectors and the protective tube for damage, and terminals for deformities.
