Fleets should ensure advanced driver safety assistance system (ADAS) sensors are recalibrated after repairs to make sure they work correctly, said Steve Greenway, senior partnership manager at Nationwide Windscreen Services.
“All new cars are being equipped with some form of ADAS,” he told visitors at Fleet Management Live. These include autonomous emergency braking, lane keep assist and adaptive cruise control, many of which rely on sensors mounted behind windscreens.
Their accuracy can be affected by certain repairs or maintenance tasks, such as windscreen replacement and wheel alignment, as well as mechanical and accident repairs which affect the geometry of a vehicle.
Neil Hilton, head of business development, garage equipment, at Hella Gutmann, said: “If sensors are not calibrated correctly, then occasionally you will get warning lights on the dashboard, but more often the most common symptom is incorrect function and then you get deactivation of the corresponding ADAS system.”
Greenway added: “It is best practice requirement for sensors to be recalibrated.”
