Frequently Asked Questions
What does the seat track position sensor do?
It reports the front-to-back position of the seat to the SRS module so the airbag system can adjust deployment force based on how far the passenger sits from the dashboard airbag.
Can items stored under the seat cause this?
Yes. Items under the seat can interfere with the sensor or damage the wiring, causing intermittent or permanent faults.
Is this the same as the seat occupancy sensor?
No. The seat track position sensor measures the seat's sliding position, while the occupancy sensor detects whether someone is sitting in the seat and their approximate weight.
