Is ADAS calibration needed after replacing a steering rack or steering column?
Short answer: Usually a steering angle sensor calibration is required, and some makers also call for an alignment and a camera calibration after steering component replacement; follow service information for the sequence.
The steering angle sensor tells the stability control and lane keeping systems where the wheels are pointed. Replacing a rack, column, intermediate shaft or clock spring can change the relationship between the steering wheel center and the actual wheel angle, even if everything is reassembled carefully.
Most procedures start with a wheel alignment, because tie rod position changes with a new rack. After toe is set with the steering wheel centered, perform the steering angle zero point calibration with a scan tool. Electric power steering racks may also need an end-stop learn or a software configuration step. Some vehicles list a forward camera calibration afterward.
Finish with a road test, checking that the steering wheel is straight, stability control lights stay off, and lane keeping assistance centers the vehicle normally. Support the vehicle on rated stands or a lift during the repair, and never work under a vehicle held only by a jack.
