Hello,

A good video on how to test the clock spring, this one is removed from vehicle:

There are 2 types of driver air bag, with single or dual stage ignition
So, the clock spring will either have 1 or 2 airbag squibs.

You will need to remove the steering wheel air bag to carry out any tests on the airbag clock spring.

To remove the airbag first disconnect the 12V battery.

A good video how to remove airbag/steering wheel:

See image below for wiring/pin data

Continuity testing is best done using a voltmeter on ohm setting.
