Lane Departure Warning (LDW) and Lane Keep Assist (LKA) utilize a forward-facing camera, typically positioned near the rearview mirror, to detect lane markings and maintain vehicle centering. When functioning correctly, these systems are unobtrusive; however, malfunctions can have severe consequences. Thus, proper calibration of Advanced Driver-Assistance Systems (ADAS) is critical for safety. Calibration involves accurately aligning the camera and sensors to ensure they perceive the road as intended by the manufacturer. Even minor changes in camera angle, such as those resulting from windshield replacement, front-end repairs, or suspension changes, can adversely affect system performance, underscoring the importance of maintaining optimal camera positioning. As a matter of fact, many manufacturers now require wheel alignment before ADAS calibration is performed, because ADAS calibration aligns sensors to the vehicle’s geometric centerline (thrust angle) – if the wheels are not aligned correctly, it can lead to system failure or dangerous conditions. Naturally, at TechZone Auto we offer expert-level wheel alignment as well.
When calibration is done correctly, the system provides timely warnings if you drift out of your lane and applies smooth, accurate steering input to guide the vehicle back. It feels natural and predictable. When calibration is skipped or done incorrectly, the system may struggle to detect lane markings, trigger alerts too late, or worse, apply steering corrections that feel abrupt or wrong. Some drivers experience constant false warnings, while others get no warning at all. In extreme cases, the system may shut itself down or steer the vehicle in an unsafe direction.
Following OEM procedures is critical. These systems are designed to work within very tight tolerances, and guessing or cutting corners can leave the vehicle less safe than before the repair. At TechZone Auto we provide professional ADAS calibration to individual vehicle owners, as well as to hundreds of local collision shops. Our shop uses latest OEM information, state-of-the-art calibration tools, and has performed over 10,000 (yes, ten thousand) calibrations to date.
The biggest risk of incorrect calibration is trust. A driver who can’t rely on their safety systems may ignore warnings or overreact when the car intervenes unexpectedly. That split second of confusion can be the difference between avoiding an accident and being involved in one. Lane Departure and Lane Keep Assist calibration aims to restore confidence in vehicle performance by ensuring accurate road perception and response.
