Diagnostic Steps

  1. Safety Precautions

    • Ensure the vehicle is parked on a flat surface.
    • Turn off the engine and remove the key from the ignition.
    • Allow the vehicle to cool down if it has been running.

  2. Tools Required

    • OBD-II scanner with ABS functionality.
    • Multimeter.
    • Socket set.

  3. Scan for Error Codes

    • Connect the OBD-II scanner to the vehicle's diagnostic port, located under the dashboard.
    • Turn the ignition to the "ON" position without starting the engine.
    • Use the scanner to read any stored ABS-related trouble codes.
    • Note down the codes for reference.

  4. Inspect Wheel Speed Sensors

    • Jack up the vehicle and secure it with jack stands.
    • Remove the wheels to access the wheel speed sensors located near the brake rotors.
    • Visually inspect each sensor for damage, dirt, or debris.
    • Use a multimeter to check the resistance of each sensor. Refer to the vehicle's service manual for the correct resistance range.
    • Clean any dirt or debris from the sensor and the sensor ring.

  5. Check ABS Wiring and Connectors
