What’s In A Steering Column: Haptic Feedback
I-CAR · November 25, 2019
Summary
This article explains that modern steering columns contain complex haptic feedback systems, which use motors and control modules to vibrate the steering wheel for lane departure and lane keep assist alerts. Because these systems are computer-controlled, they can set diagnostic trouble codes (DTCs) and require specialized diagnostic scanning and testing to ensure proper post-repair functionality.
What to do on the job
Perform a diagnostic scan to check for DTCs and verify that the lane departure warning/lane keep assist systems are enabled and functioning properly during post-repair testing.
How to use it
Use this document to justify the necessity of pre- and post-repair scanning on vehicles equipped with lane departure warning or lane keep assist systems, and to support labor times for verifying and testing haptic feedback steering column components.
