11' Megane 3 RS (ABS fault)

  1. Hi all,

    Last weekend, I inserted the card key before start the engine, Red warning brake fault occur, abs, esp. 2 fault code per below:
    DTC 505004 ABS
    DTC 401001 ABS

    Technician told me that I need to replace the ABS module, any idea/advice? Thanks.

    Noted that I do not upgrade/maintenance any brake parts in Apr, I already checked the below, all look fine: Brake fluid level, fuse #12 5A, ABS sensor and I already replace new battery.

    Last question, it is necessary to re-program/re-map if I plan to replace a 2nd hand ABS module?
     
  2. Have you checked the large 80 or so amp fuse on the pos+ terminal of the battery?

  5. I had a similar issue, where the ABS light came on etc.

    Mine turned out to be a faulty speed sensor.
