Your Lancer X ABS light staying on usually points to a wheel speed sensor fault. Learn the likely causes, what to check first, and if it’s safe to drive.
Seeing that amber ABS light glowing on your Lancer X's dash can be unsettling, but don't panic. In most cases, it's a wheel speed sensor that's either dirty, damaged, or has a wiring issue. The ABS system uses these sensors to monitor wheel speed, and when one fails, the computer can't do its job—so it turns on the light and disables ABS.
