I saw a topic on an industry forum run by glassBYTEs that was titled “Hey Bob Beranek!”  Well, I couldn’t ignore that and promised the subject writer I’d answer his questions as best as I can. The questions and answers may help you too.

  1. Should every new install with ADAS be re-calibrated (or at least checked), or only if things don’t seem to be working accurately?

According to Opti-Aim, a recalibration should be completed on every ADAS equipped vehicle after a windshield replacement. Why? The reason – although a fault code may not be triggered/tripped, the camera, bracket, or both may not be perfectly positioned for maximum performance. As I’ve said in previous posts, even if the camera or LIDAR is a millimeter off, it can cause big differences at the reference point. It can mean feet or yards off of being perfect.

  1. What about aftermarket glass? Should only OEM glass be used when ADAS is involved?

Most third-party calibrators can recalibrate aftermarket parts if the ARG parts meet OE specs. However, if the bracket is so far off that it’s outside the limits of the units aiming ability, that part will not allow the unit to be properly recalibrated.

The only way of making sure the glass can be recalibrated properly in advance is by using OE parts. That’s why many dealerships require OE glass before agreeing to do a recalibration. They don’t want to waste time recalibrating something that doesn’t work, or they want to limit their liability.

  1. Is an aftermarket glass from say Pilkington (DOT-15) the same as an OEM Honda branded glass that is marked Pilkington (DOT-15)?

That’s a good question for Pilkington. I will let you know what I find out. I do know Pilkington guarantees they can recalibrate any Pilkington part no matter if it is OE or not, if their calibration tool (Opti-Aim) is used.

Recalibration is complicated and a rapidly changing issue. There are liabilities, products, tools, adhesives, procedures and vehicle design both public and proprietary that come into play. There are scanners, lasers, cameras, LIDAR, and sensors of every type and style mounted to dozens of different parts of the vehicle. Some apply to us and others don’t. We all hope for is a simplified or standardized system that can be recalibrated or self-calibrated. Right now none of us know it but I’ll do my best to keep you up to date.

 Merry Christmas and Happy Holidays to all of my Readers!
