What’s In A Seat: Active Headrests
I-CAR · December 9, 2019
Summary
This article highlights the evolution of automotive seats and active headrests, which utilize mechanical or pyrotechnic systems to mitigate whiplash during rear-end collisions. Because these advanced safety systems are computer-controlled, they require diagnostic scanning to identify Diagnostic Trouble Codes (DTCs) and ensure proper post-repair functionality.
What to do on the job
Identify if the vehicle is equipped with active headrests and perform a diagnostic scan to check for DTCs and verify proper system operation.
How to use it
Use this document to justify diagnostic scanning charges and labor time for inspecting, resetting, or replacing active headrest components following a collision, especially when dealing with pyrotechnic or mechanical restraint deployments.
