Sub-step 2: Locate the wheel speed sensor; it is typically mounted on the brake rotor or hub assembly.
Sub-step 3: Disconnect the electrical connector from the sensor.
Sub-step 4: Unscrew the sensor from its mount (usually requires a Torx or socket wrench).
Sub-step 5: Install the new sensor (if faulty) by reversing the removal steps and ensuring it is securely mounted.

3. Brake Fluid Check and Replacement

Sub-step 1: Locate the brake fluid reservoir under the hood.
Sub-step 2: Check the fluid level; if low, top it off with the appropriate DOT-rated brake fluid (refer to the owner's manual for specifications).
Sub-step 3: If the fluid is contaminated, drain the reservoir and replace it with fresh brake fluid.

4. ABS Module Inspection
