    Hi Chap Sir,
    i have Toyota harrier 2008 hybrid which is domestic Japan model of Lexus RX400h. I had an issue with my master brake cylinder last year and I changed it with the used part and I spent around $1200 issue was 1) C1246 - master Cylinder pressure sensor
    2) C1256 - Accumulator low pressure

    now again I am getting the same issue and my Acumirator motor runs continuously with 10sec bracks. since I saw this post and above someone says your suggestion worked and I just wondering can mine also sorted. can you please help me?


    regards
    Virantha
