Code result
C0081
Wheel Speed Mismatch
Moderate severity
What it means
Rear axle wheel speeds differ beyond the plausibility threshold. Wheel-speed signals feed ABS, ESC, traction control, transmission and odometer — a single dropped signal disables all of these safety functions until repaired.
Is it safe to drive?
Use caution
The vehicle is usually drivable for short distances, but the problem can worsen or affect emissions. Diagnose and repair as soon as practical.
