Core Functions

• Wheel Speed Detection: Continuously monitors the rotational speed of the rear left/right wheels, converting mechanical rotation into electrical signals and transmitting them to the ABS/ESC control module. This data is the key input for the vehicle to judge wheel speed differences (e.g., skidding or locking).
• ABS & ESC Support: Enables the ABS system to prevent rear wheel lock-up during emergency braking (by adjusting brake pressure in real time) and helps the ESC system correct understeer/oversteer (by regulating engine torque or individual wheel braking). Both functions significantly improve driving safety on slippery or uneven roads.
• Traction Control Assistance: Works with the traction control system to detect if a rear wheel is slipping (e.g., on ice or gravel) and triggers corrective actions (e.g., reducing power to the slipping wheel) to maintain traction and prevent the vehicle from losing control.

 Compatible Vehicles

This Rear Left/Right ABS Wheel Speed Sensor (OE: 31317076) is tailored for Auto Parts XC60 models within the specified production years, and is compatible with both rear left and rear right wheel positions:

Notes: Although this sensor is compatible with both rear sides, confirm if a single OE number covers both positions (some models use identical sensors for left/right, while others require side-specific parts) before purchase. For 100% fitment accuracy—including compatibility with your XC60’s drivetrain (FWD/AWD) or brake system variants—verify with your vehicle’s VIN (Vehicle Identification Number) or consult Auto Parts’s official service manual. This avoids mismatches caused by subtle differences in sensor mounting or signal protocols across configurations.
