    I have prius 2011 200k KM equiped with PCS, for some reason while i am driving msg appeared on the dash ( Check pcs system / check hybried system) with orange triangle and start losing the speed , i check the car with OBD using the following app (torque pro, car scanner) no errors, also i have check the car with techstream also there are no errors stored.

    With two following procedures i can clear the errors
    - clear errors by using the torque pro
    - start the turn off the car three times and on the forth time everything's back to normal

    This happening almost eveyday, i though there are some dirt on the lens (front toyota logo and underneath sensors) i clean it but nothing happened.


    For your kind help.

    You need techstream to read the hybrid system error. OBD2 generic reader might not work.

    Going to the Dealer tomorrow. They have Techstream. Last 2 weeks ago, it has same issue so I called some technician from FB. They replaced the traction Battery. Clear the codes. But they couldn’t clear the PCS system. It was fine for 2 weeks the indicator arrows in the dash came back. They said that the rear speed sensor might be bad. I took the car home replaced the Rear passenger hub. Tried resetting it by shorting the terminal 4 and 13 Where you put the OBDIi reader. Start the car but the Check PCS system still there with the ! Light abs lights break lights still lit. It’s up to the Dealer now what can they do. I might just end up trading it in‍♂️.
