Test continuity from SRS module to side airbag connector
Frequently Asked Questions
What causes wires to break at seat track flex points?
The seat harness must flex every time the seat is adjusted. Over thousands of cycles, individual wires can fatigue and break at the flex point near the seat track.
Is this an expensive repair?
It depends on the cause. A simple connector repair may cost $100-$200, while replacing the side airbag module in the seat can cost $400-$800.
Can I see the damage myself?
You may be able to spot obvious damage by looking under the passenger seat, but proper diagnosis requires measuring circuit resistance with specialized equipment.
