ABS Light coming on at specific Speed

[Rubes]

Hello,

So just recently i've started to notice that my ABS light comes on at a specific speed and stays on for about 20-30 mins (haven't timed it). The speed is around highway speed. I've got a DC5S. Anyone know of this issue? Why it's coming on? Is it a fault? Or is it meant to when your going faster.

could be speed sensor thats faulty, check ur brake fluid levels, could even be the abs module itself, doubt it though, just trouble shoot through the service manual, gives a complete run down on the exact problems

check the ABS ECU for codes to point you in the right direction

sound like wheel speed sensor problem.
