    2013 Prius (2?). 115,000 Miles. (Purchased with roughly 100,000 miles late October 2016).


    Driving (normal) today and noticed the following lights turn on:

    • TRACTION
    • BRAKE
    • ABS
    • ((!))

    All came on at once. All are solid (not blinking).

    Car is still driving great. Brakes work fine, although a little stiff (ABS is off).



    CHECKED SO FAR:

    • Brake Fluid: Level, no apparent leaks
    • Brake Pads: Nothing unusual
    • Fuses: No issues
    • Tire Pressure: No issues
    • 12v Battery: Healthy, disconnect and reconnected
    • OBDii: No codes — tried with my cheap one and also an advanced one from garage-mechanic



    VARIABLES:

    • I drive in San Francisco, the most transmission-friendly city on earth.
    • It rained earlier in the day
    • Last oil change 2 weeks prior at Midas (they also did a brief inspection, which supposedly included brakes. Only thing mentioned was to replace Cabin Air Filter, which I rejected, along with a tire rotation).



    MY SITUATION:

    I'm on a super-tight budget... Used all my savings to buy the car (to Uber/Lyft) and move to SF just 2 months ago — the cost of parking alone has nearly crippled me. I don't trust the Toyota dealership or their prices, and will not go until I've ruled out every possibility with 3rd party mechanics.



    MY STRATEGY (and really my only option):

    To deduce possible issues, in order of cost.


    Any and all help is greatly appreciated, and I'd like to thank everyone in advance for taking the time to read this. It really means a lot to me.


    P.S. I'm posting this on the evening of Friday, Dec 23. If anyone in SF has a(n affordable Prius) mechanic to recommend, let me know...especially if they're open Saturday, Xmas Eve.

    I also ask that we keep the comments/replies strictly relevant so that any Prius owners with the same issue after me can find the fix in a clear, timely manner — I will be following up once I've reached a solution.

    THANKS AGAIN, Happy Holidays!

    Sounds like a bad wheel bearing,you need techstream software to find out which one

    Hey Tankyuong, thanks for the quick reply. Much appreciated!

    Techstream? Is that Toyota's in-house software? Are they the only ones who have it, or can other mechanics get access?

    What makes it sound like a bad wheel bearing? Here's what I forgot to mention in the original post: I've found dozens of threads with the same issue, but nearly all ended up having different solutions.

    Thanks again,


    Tobias

    I had a similar issue this week in my 2013, but I only have 41,000 miles on it. The ICE would not start. Virtually all of the dash lights except the fuel economy center section stayed on. Replaced the 12v battery, good to go!

    Welcome to Prius Chat (y)!

    When the lights came on at once, what was the car doing (hit a pothole, drive through standing water, just start out from a light or from a parking space after sitting for awhile, open stretch of road at xx speed,etc.)?

    You say the 12v is healthy, what were the readings off of the multimeter (at rest, under load, after a drive)?

    Checked electrical connections to ensure no loose ones?

    Keep us posted(y)!

    Wondering if one of the wheel rotation sensors (part of the ABS system) is not functioning properly.

    If there are warning lights, there will be DTC codes but as was pointed out Techstream software (a mini-VCI cable can be purchased with software from Ebay to connect to the OBDII port) may be needed to read them.

    If you are in SF there are lots of good hybrid mechanics around - Luscious Garage being one of them.

    Good luck and let us know the cause of your car's problem.

    Possible I guess but I think there are other things ahead of that on the "likely" list.
    Wheel speed sensors are the most likely cause.

    The good news is that you have "standard" brakes with the ABS off.
    The bad news is that you might need a LOT of brake work on a car with 100K miles.
    An independent shop is a good place to start.
    But given your financial situation be SURE to ask up front what the diagnosis will cost you AND that they won't do anything to it that will require repairs before it's drivable again (hold it hostage to a big repair bill). Get both of those things in writing.

    Do the brakes feel "off", ie: they work, but feel a little different? I know our 2010 has had several instances where the lights came on, coupled with "Check Hybrid Sytem" notice, and a noticeable difference in brake "feel". They work, but seem to have reverted to some default mode, not quite as responsive.

    In your shoes? I would at least get a diagnostic done at a dealership, should not exceed $100. Depending on what codes they find with Techstream, it may be under warranty. Anyway, go from there.

    There's an outstanding indie garage in San Francisco called Luscious Garage. They are the best Prius mechanics in the nation. Their prices are also great. Take it there.

    i am having same problem now all lights of brake systems are on , abs, traction control, skid control and emergency brake. lights came on when my car was at the dealer to check the vibration i had last week, @Raytheeagle , my car is at the dealership again, they told me i need to replace the whole ecu over $4000. could this be a minor thing like others suggested here? like cheap obd scanner i probably have ? or speed sensor? , my abs is not working now and i get a beep every time i hit a hump probably coming from traction control. any ideas? need help

    Do you have Techstream or know someone who does?

    If you are experiencing drivability issues, there are issues. What codes did the dealer pull to come up with the ECU replacement?

    Keep us posted (y).

    dealer did not replace anything yet, codes are b1585, c1345, c1451.
    now , the regenerative not working and no abs or traction at all, takes a long time for battery to charge and it seems to be mostly on the 2nd bar.
    i went back to the dealer and left the car there, told them its their fault. i really did not have this issue when i came in to the dealer at saturday morning, im sure they messed with the wire harness that goes to the traction ecu or created some short circuit. they will call toyota HQ tomorow

    Well the c1345 is related to the skid ECU, so it sounds reasonable:(. One option is to source off of eBay and replace.

    For c1451, here’s a good read:

    How do you reset ABS light & yellow ((!)) ?

    I’d see about the brake bleeding invalid mode, then reset the battery and see if c1345 returns;).

    Keep us posted (y).

    i dot have that scanner . dealer tried several times to reset but no success, other codes came at 2nd attempt of reset, for them it is obvious they didnt do anything wrong, but they could have damaged a wire or the ecu themself. im not letting them convince me its my fault. anyways after reading today of some other members posts, tthis issue could be many other things and not only the ecu.
