Working on cars with Advanced Driver Safety Systems (ADAS) brings a unique set of challenges. As an automotive technician, it's important during an inspection to be on the lookout for any signs that these high-tech systems might be out of calibration. Even something as minor as a fender bender or a replaced windshield can throw off ADAS calibration, affecting how the car's safety features perform.
When servicing or inspecting a customer's 'newly purchased used car' with ADAS, it's important to be aware of any knocks, bumps, or details that could obscure a camera or events that may have previously damaged the sensors - like a crash. A car might look great on the outside and even drive smoothly, but if its ADAS isn't properly set up, it's not necessarily road-safe. These systems, like automatic braking or lane-keeping, can have hidden issues due to improper repairs or calibration.
For example, a seemingly perfect used car might have had a windshield replaced but the camera wasn't recalibrated correctly. So the adaptive cruise control set to adjust the vehicle speed when a car is say 20 feet in front of you, might not register until 4 feet! Because the camera wasn't properly calibrated the vehicle is now too close to the car in front of it.
So when a customer arrives with a 'new to them' used car at your shop, either for inspection or real repair, it requires more than a physical inspection. The ADAS systems should be inspected for proper operation by use of a scan tool and/or physically driving the vehicle. This responsibility might be hefty, but for those of us in the industry, it's just part of the job. Properly functioning ADAS systems can be the difference between a narrow escape and a serious accident!
