C0035High urgency

Left Front Wheel Speed Sensor Circuit Malfunction

Chassis · ABS / Stability Control

ABS and traction control likely disabled — drive carefully, avoid hard braking.
What this means

The left front wheel speed sensor is producing an abnormal or absent signal. This disables ABS and potentially ESC/traction control systems. You can still brake normally but will lose the anti-lock benefit in emergency stops. The sensor itself is the most common failure — the wiring harness is a close second especially in regions with road salt.
