    I'm getting codes C1241, C1259,C1310, P1241. All of them have to do with the skid control ecu. Should I replace the ecu? Any suggestions?

    DTC P1241 is not a valid Prius DTC. Perhaps you meant C1241 which points to low voltage on the 12V bus?

    DTC C1259 and C1310 both point to a problem with the hybrid drivetrain.

    My suggestion is that you should get Mini VCI to read the DTC because your car probably has a problem with the hybrid drivetrain and additional DTC will have been logged by the hybrid vehicle ECU or the traction battery ECU.

    It is premature to talk about replacing the skid control ECU.

    Another suggestion is that you let us know when the car last operated correctly without reporting any DTC, and whether anything unusual happened to the car prior to the DTC being logged (like the car running out of fuel, suffering accident damage, being in a flood, etc.)

    I'm sorry but I don't quite understand. Do these codes show up on the dash display or are you using a specific code reader?
    Thanks

    Thanks for the reply,
    The car was running fine then the triangle with exclamation point, and, check engine and ((!)) came on. It kinda felt like it didn't wanna more when I hit the gas ( like it did before I changed the hv battery). I replaced it with a refurbished one from reinvolt ( bought out by dorman).
