    Recently replace the passenger wheel bearing and wheel speed sensor on my 2021 Toyota Prius XLE AWD-e.

    After replacement, basically every error message relating to the ABS actuator is freaking out.

    After extensive research, it looks like it’s a somewhat common ABS glitch that happens with the Prius.

    I believe that jumping the ABS through the pins, pumping the brakes 8 times, and then resetting the car will fix my problem.

    The only issue I have is that I cannot find an OBD2 diagram for the 2021 Prius, and I don’t want to jump it incorrectly.

    It looks like pin 4 is almost always the Chassis Ground, but which pin is the Brake pin?

    Any/all help or suggestions welcome. It is not a faulty wheel bearing or sensor, as we get accurate live data from the sensor.

    Thanks in advance.
