Care of modern sensors, etc

Yap, PRIME and I assume all PRIUS with a forward-facing camera needs re-calibration if the windshield is replaced. Some glass shops can do it, some can not. I have seen the shop manual posted somewhere on a different thread. It is not a difficult task if you had a place to do it yourself. When I had my windshield replaced, my dealer did it for $150.

 

In theory, you could. But the recalibration procedure itself tests the alignment of the camera much like the way you adjust the headlight beam. I don't think the misaligned camera throws an error code, so you might have a hard time testing it on a road unless you have some very straight flat road with a line and strategically placed objects (or cars).

I guess if you have a window replacement without recalibration, you could just drive and test all the features that use the forward-facing camera, like PCS, DRCC, line departure warning, auto headlight, and if they are not functioning correctly, then you could ask for recalibration. But for a safety reason, I wouldn't recommend doing that just to save a few hundred bucks.

 

Step one of alignment after replacement of front suspension components:

NOTICE:

If the wheel alignment has been adjusted, and if suspension or underbody components have been
removed/installed or replaced, be sure to perform the following initialization procedure in order for the system to function normally:

Perform zero point calibration of the yaw rate and acceleration sensor.
