Sorry for the translation (google). I am Spanish.
This happens to me a little after changing the brake pads. checked again that everything is tight and in place.
Sometimes yes and sometimes no, the abs 1 and 2 lights come on, but it is not like when there is disconnection of the system, but something similar to 50% of light. When this is the case, sometimes it flashes very quickly on the same light (it does not go out between flashes). It turns on or off sometimes after some strong bump, but other times it does it alone, the Poltergeist always starts from a few minutes running.
With the warning lights on, I then checked the ABS braking hard with the rear wheel and it works correctly. I accelerated strongly in the wet and the TCS was fired (correct).
I realized then that the indicator light of the TCS (the orange on the left side) does not come on.
Does anyone know if it is related that when this light melts, is it affecting the correct functioning of the central lights of the ABS?
