I have noticed that sometimes the windscreen in front of the “front camera” (i.e. the one used for lowering beams, etc...) gets fogged up and this affects the functionality of the camera for all of the functions that it is used for. Air conditioning and the windscreen defroster eventually take care of removing the fogging, however this made me think that, as that area is not sealed it will eventually require cleaning (on the inside). Is it possible to temporarily remove the camera plastic casing so that one could clean the inside of the windscreen with a cloth?
Supposedly, it is. I haven't needed to, so this is not from personal experience. Removing LDA Sensor Cover | PriusChat
Thank you. Unfortunately the “instructions” are not very clear. I have asked for further information and hopefully the person that did it is still on the forum. Cheers
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!
I could be wrong, but it seems to me that one could remove the casing without disturbing the camera itself which seems contained within such casing, but independent from it. Once the casing is off, there should be enough space to clean the windscreen with a cloth.
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.
Wow, thank you very much, this is great. I must say that it looks a bit unnerving as my previous experience with plastic is that sometimes it just snaps... However, you have proved my suspicion that that part of the windscreen WILL need to be cleaned from time to time. Thanks again. At some point I will have a go in my car.
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.
I am not fully convinced. The operation for changing the glass involves dismounting the camera and putting it back in place, which is exactly what we are doing here. Unless their concerns are about using non proprietary glass with different optical characteristics? But this would seem odd. Then again, a camera is a camera is a camera. If it was calibrated before I started the operation, then it should still be when I put it back together. Micro movements are irrelevant in any camera operation, unless it is mounted over a microscope.
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.
Hello Jerry, First of all, thank you for the very helpful tutorial you did for us. I know this post is a bit dated, however I have an issue with my ’22 Gen4, the LKA does not work at all, only detecting one side briefly for a second then off, so I’m guessing PCS won’t work either… after cleaning the outside windshield & inspected I can see there is some kind of brown-ish fog or condensation between the inside of the windshield and the camera (that triangle cavity) not clearing with defroster, so I’m sure that’s the culprit. My vehicle is less than 36 mo. and with only 18k miles, so it should be under warranty + plus the extended warranty the finance guy begged me to purchase stating he needed to provide food to his children --anyhow… I have an appointment at the dealership this coming Friday for it, as they state they need diagnose the problem so they can determine if it’s covered under warranty or not. It should be certainly covered as the car has no modifications nor I attempted to tamper with it plus that component is part of Safety Sense 2.0, but I’m afraid they can play the “no faulty code found, no claim” card. So in that case I’m planning on following your tutorial. My only concern is if the camera being off by a micro movement (by unclipping it and clipping it back after cleaning the glass) you know, half of a millimeter when projected to a distance can be huge at the end, perhaps there are plastic tabs getting bent a bit never returning to original position causing micromovements… so I’m scared if that’s the case the car may apply brakes per PCS incorrectly by seeing an overpass or something due to being un-calibrated. Since you did it for this tutorial, did you have any issues with calibration thereafter? Also, did you see any gasket or seals on the camera assembly that gets deteriorated making this more a recurrent thing? Is your LKA working reliable after you did the clean up? Hope you can clarify. Thank you for your support. -FC
PCS and adaptive cruise control depends on the forward radar located behind the Toyota emblem, in the engine bay. You should not be getting AEB or FCW as a result of miscalibrated camera.
Mine seems to be all closed in, so it never gets fogged over. I do think it may be impaired by a muddy windscreen, because I noticed it wandering over to the shoulder a bit more than normal when it was dirty.
