the connectors for damage, and the terminals for
deformation.

2. Install the air bag module to check fit or alignment with the

steering wheel.

3. Check the steering wheel for noise, binding or difficult

operation and excessive free play.

.

Seat belt with pre-tensioner
1. Check the seat belt for damage or deformation.
2. Check the seat belt with pre-tensioner for cracks or

deformation.

3. Check that the unit is installed correctly to the vehicle body.
