Toyota Sequoia Lights Brake, VSC Track and BSC OFF

Look when the pedal gets hard the fault is the servofrane, the menbrane dilates and dies, nothing more than that

Hello, I have the same problem with my toyota Runner bagonet, I see the VSC Track and VSC OFF, the Scanner does not come out failure code. I wanted to know how this failure is diagnosed or how it is given. or where can I lower the repair manual. or some tutorial. Thank you already

Friend Your problem is the servofreno, he has a connector on the left side that indicates to the module, when there is a problem and commands to turn on those lights, change it and automatically will be erased, something more checks the electric connectors that the master brake cylinder has that this also has to do with

Thank you very much dear friends for commenting and cooling issues that can be very much that can be very helpful for each other. The last comment of the electrical system with the module is very close to what happens. I will tell you what are the possible causes and you will tell me when you fix your car if it was that or not, to a friend who asked through this blog contemporas the possible quasas who are investigating from this migraine that he has returned with the problems of the American mobility especially the toyoyas, since the Japanese almost never has this type of problem.
As far as the mechanical is, that is, it is its ABS module that does not work, you have to change, the module or computer of that part is the last thing that we must think that it has been torn. First, scanning is made with scanners that are specifically to the brand, model and year of the car, also take into account that there are engines, others for brakes, others for air conditioners, etc. Not as some mechanics say that with that scanner reads everything is because it does not have the others. Second if the scanner does not want to read or it is hard for him and does not want calibrate After all this, you will have to review the ECU OPLULO or brain of the ABS as well as the module or brain of the VSC OFF and VSC Track. I have not been able to do all these steps that after wasting so much time and money and a lot of research and I could draw these conclusions since not even the same Toyoya technicians know how to admit their defects and how to solve them to the users because as they will see all consultation is paying, I believe that enough with the vehicle does not? Have if they can contribute with new ideas and contributions, and Manueles a hug from Santa Cruz Bolivia. This diagram will give you an idea of ​​those who speak to them.
