    Hello all I’m Amar from France, I’m new.
    Got a 2021 Prius + / Prius V ZVW40.

    I'm facing some problems with the Abs electrical circuit (Left rear sensor error from Techstream) more precisely the output of the Skid control ECU which i could not managed to find the location to make a voltage measurement.
    I ve checked the voltage at the Left rear sensor = 0V DC (compare to the
    Right rear sensor = 14V DC).
    Today I ve checked the voltage at the strap connector inside the car
    = 0V DC.

    Has anyone the TOYOTA PRIUS V / PRIUS α / PRIUS + 2012 - 2021 SERVICE MANUAL in order to get the wiring diagram (found some on internet but not the right one)

    Thanks for your help.

    For the most accurate diagrams you need to access Toyota's TIS online system.

    However the odds are good the speed sensors connect to the skid ecu as shown below. Zero voltage usually means a bad wire, typically in the moving sections of the cable.
