    Same day i got “ P lock malfunction when park “ with a non stop beep
    One week after i got the abs light on and a circled sign and a slip light too
    And the last week t GOT THE STEERING WHEEL LIGHT ON TOO
    SO NOW ITS HARD TO MOVE THE WHEEL
    i take it to different places no one knows what’s wrong with my car
    I take to the dealership to do the diagnostic and they say that they do know i pay 140$
    And they say that i have to pay 470$ for another diagnostic , the say its may
    I find a problem with the water pump and i changed
    And I thought its the engine ECU
    I changed and programmed but its not that the problem
    One of the mechanics told me its maybe one of the ecu

    What was the voltage and did the Prius get to “ready”?

    P3014 was displayed. What was that blocks voltage (or the individual modules) compared to the others?

    Any accident history or rodents around the area you park?

    What was the 12 volt battery showing at rest overnight?

    If according to what you say is that this problem occurred while in that pothole, tgr codes in my view were triggered by that impact.

    Clear the codes, and see if it comes back again. If it does not come back, then it was a result of the impact. Maybe ecu on the battery pack area, has lost communication with dome of the sensors on that car.

    The battery block #4 should not cause the loss of CAN between the other sensors as shown on your scan.
    Do you have a tech stream to see if you could access the steering sensor side and calibrate it?

    Ah the root cause:).

    More questions:
    • Did the tire go flat?
    • Have you checked the wiring to ensure it is all there and no damage?
    • Have you had it on a lift and checked for damage?
    • What package level is your Prius?
    If you don’t have access to Techstream, I’d look up another shop as you will need professional software (like Techstream) to clear the codes once you finish your investigation and fix the problem.

    2 members who have shops near you that could help are @Avi's Advanced Automotive and @sfv41901 from Hybrid Pit;).

    Good luck and keep us posted (y).

    There are speed sensors and if they are misaligned or the electronics are bad, you’ll have issues;).

    You’ll need to put the rear up and investigate. From your comments above, this might be above your skill set, so I’d look to contact the members mentioned above.

    Good luck and keep us posted (y).
