    Is there a way to recalibrate the skid ecu with a techstream? I seem to see alot of older & some recent post about needing to replace it. But has anyone been successful in just recalibrating or resetting one?
    I am getting C0215, c1242, c1247, c1311, c1313, c1377

    Many will use techstream, doubtful if there are any other options.

    Maybe this post/thread would be helpful : Trouble codes after skid control ECU replacement | PriusChat

    Have you have already been through the step by step workups for the above DTCs ? (C0215, c1242, c1247, c1311, c1313, c1377)

    Please follow up and update in this thread.

    Ok so the Prius had a bad battery & was throwing all kinds of codes before the replacement. Now it is throwing just 2 abs/vcs/trac codes: C1256, c1345. There is no loud buzzing warning & the brake pedal is firm. Before battery change it was not throwing the C1256.. Why isn't the car setting off a buzzing assuming as most do the abs accumulator is bad? Any tips would be helpful.. Also I tried resetting the codes with no luck.

    Did you click on the small snowflake looking icon to retrieve the 'detailed code' (subcode, INF, or secondary code) ?

    Knowing the subcode(s) can help narrow down the issue and potentially save time, money, and effort in solving the problem
