Hello
I have lancer ralliart 2006. When it's speed above 130 km/h any touch of braking pedal will lead abs to start working without any warning light. I did a test for wheel speed sensors and all of them are the same. Please I need help.

i'm not sure I understand what you're saying...what do you mean by "ABS to start working"?

Start working means. Start vibrating without any need. Hopefully it will be cleared now.

are you sure that's not just the car vibrating? you say the ABS warning light doesn't come on...that comes on when the ABS system is faulted, so if the system at least thinks it is working OK, the light should remain off..

so even if you only very lightly pressed the brake pedal, you're saying anti-skid system engages? That would mean part of the system is detecting a skid. so if you are slamming on the brakes, then what you describe is perfectly normal. If a light press of the brake pedal causes it, then I would inspect the ABS rings.

yea I don't htink that's the abs system that's vibrating, might be a wheel bearing or you might need new tires.
