Hello, I have an error says " check pcs system. I took the car to dealers but it seems they are guessing as they tell different reasons. I found the brake oil lower than it was but not sure if it could be the reason. I had it scanned and here's the result: ABS/VSC/TRC = FAULT Advanced parking guidance system = FAULT Prius 2010 I attached a screenshot
Sounds like the PreCollision System. How many miles? Have you got a code reader or know someone who does? Any work to the brakes recently?

If it is the pre collision system, that would include the seatbelt pre-tensioners also, which might be another site for a bad electrical connection to occur. But the posted diagnostic codes in the computer would be helpful if you have a Techstream type of reader that will correctly interpret them.
There is a buzzing sound every 10 seconds comes out of the left side of the engine whenever I come close to open the car and then the sound continues It's 150.000 mile This is the sound I hear even when the car is turned off 20161031_111519 by Zuinat posted Oct 31, 2016 at 2:04 PM
the video didn't load. did you scan with a toyota specific scanner? also, you may want to try disconnecting the 12v negative for a few minutes, but you might want to scan codes first. the buzzing noise is probably the brake accumulator. has it gotten worse, or is it new altogether. mine buzzes when i open the drivers door, and now and then while driving.
The site doesn't support the vid. Here's a picture instead. this thing in the picture always keeps buzzing and vibrating and yes I scanned it
Is this a sound you hear when opening the driver's door, buzzing that goes on for about 10 seconds? If so, that is normal; it's the brake system pressurizing.
it's like the sound I hear when I open the door but it's constant and not sure if it comes from the ABS or something else. it comes from the thing indicated in the picture
Here in the states we had a recall for the brake booster. Did you get one in your neck of the woods? It sounds like the system is continually trying to pressurize but cannot. Sounds like blow by of the fluid or there might be air in the system. What is your brake pad thickness? Any work done recently on the brakes? Do you use a lot of regen braking or use the friction brakes? Have to use the brakes for an extended period of time where heat may have boiled the fluid, creating air in the system?
