    Hey everyone,

    I am new to the community and I am looking for advice in troubleshooting problems that have recently come up with my newly purchased used 2009 Toyota Prius.

    A little history on the car: I have had to the car for about three months and overall it has passed general inspection and has driven fairly well. The car has 114,165 miles on the odometer, a clean CarFax, and has been maintained frequently over the years.

    Last week, while driving on the highway, as I was accelerating past 70 mph, the red warning triangle showed up on the dashboard and I immediately pulled over onto the emergency lane. It was the only light that came on and it was on for less than 5 seconds and then the light went off when I decelerated. The accelerator was less responsive when the light popped up. After some time stopping, I then drove home under 70 mph and the ride was okay; no lights came on and the car was accelerating appropriately.

    I took it into the auto shop the next day and 4 DTC codes came up:
    C0200 Right front wheel speed sensor signal fault
    C0205 Left front wheel speed sensor signal fault
    C1241 Too low or too high battery voltage
    C1300 Fault in CCU

    Found the front anti-lock brake sensors having a delayed/erratic operation on acceleration. Also found the skid control module in need of replacement. A battery test was done with the results saying the the battery was in good condition.

    I was quoted around $3K worth of repair costs + labor, in the case of my car being in the worst case scenario. I am unsure of what to do right now because my car continues to drive fine and I am a little skeptical about both ABS sensors failing at the same time, especially when I got the car inspected so recently. I would like to fix the car for as little money as possible and am considering getting a used replacement skid control module and getting that installed. I am also debating bringing my car to another auto shop that specializes in hybrid repairs because my current auto body shop has told me that they are just basing repairs of off the cascade of codes that came back.

    Any advice on my current situation? And if I were to buy a replacement skid control module, where would be the best place to purchase one?

    Thanks!

    We can probably recommend some shops in CA, what area are you close to?

    You should first check the oil level on your car, make sure that's within the specified area on the dipstick. Then you should check the 12v battery, make sure it's not bad (under 12v). If the 12v battery is low, charge it up before you do any further diagnostics.

    I suspect your 12v battery may be low and causing some errors. Testing the 12v battery is usually free at most auto shops

    $3000 is a very expensive amount. I would get 2nd and 3rd opinions.

    Oil levels and battery were both checked and are both in good condition!
    I live in the Riverside/ Redlands area, not too many hybrid specialists in the area that I know of.

    In a similar situation here in Italy, the mechanic has coded all the control units, coded the steering angle sensor and reset fault memory: now everything seems ok.
    The car is an "Auris HSD" like a Prius MY13

    I was told by Toyota that I have a bad ABS actuator. I bought one used from lowmileageparts and now after having it installed by a mechanic, I was told that it is defective. I cannot get lowmileageparts to answer the phone. I have left messages and they do not return my calls, nor respond to emails. Does anybody know anything about this business? Also, the codes indicate the ABS, but I have been told it could be the ECU. Any ideas?

    In a similar situation, did you get to a resolution please?
