Clean windscreen in front of camera

Supposedly, it is. I haven't needed to, so this is not from personal experience.

I have wondered about that too. The pages and pages of instructions and warnings in the owner's manual attest to the fact that this would probably not be a DIY process. Cleaning of the interior glass inside the camera housing would require removal and subsequent recalibration of the camera. I'm just now coming up on 5000 miles and managed the other day to acquire a windshield star near the lower right corner. Darn Arizona roads. The brochure from the Safelite AutoGlass company that repaired my windshield indicates that subsequent to windshield replacement on a vehicle that has one of these Advanced Driver Assistance Systems they will perform a recalibration and warranty it for 12 months. Nothing specific to that system mentioned in the Toyota Maintenance Log.

 

I'm working on a video or at least pictures right now. It's easy to do, but it's hard to get a camera on it while doing it and my hands are starting to shake. Break time!

 

No, the camera has to come out. My wife is doing her PT for her knee replacement now. She said she would hold the camera for me when she's done. There are too many things that take two hands and there's no place to position the camera on a tripod to do it solo. I'll try to be done here in a couple hours.

 

From the maintenance manual "If the forward recognition camera has been replaced with a new one or the windshield glass has been removed and installed, it is necessary to perform Forward Recognition Camera Learning." so it looks like it's okay to remove the camera without calibrating? I haven't tried it though.

 

All done. I couldn't find a video online, so I made one. Many thanks to my patient wife who did the camera work where I didn't have enough hands.

 

In the Repair Manual (more info), Toyota writes, “If the forward recognition camera has been replaced with a new one or the windshield glass has been removed and installed, it is necessary to perform Forward Recognition Camera Learning.”

I assume the inverse is true, too: if neither the camera nor the glass is new, then learning (adjustment) isn’t needed.

 

Given that your info doesn't give a location, that's possible. I have no idea how cold it is where you are.

Not in the least. It works just like before since it went right back in the same place. What surprised me was how loosely it fits in its bracket and how loose the bracket is in its mount.

 

Awesome! Thank you for creating the video, Jerry.
