1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative battery terminal to ensure safety.
Allow the vehicle to cool down if it has been recently driven.

Tools Required:

OBD-II scanner
Multimeter
Socket set
Torque wrench
Brake cleaner
Wire brush

2. Inspect and Clean Wheel Speed Sensors

Sub-step 1: Locate the wheel speed sensors at each wheel hub.
Sub-step 2: Remove the sensor mounting bolts using the socket set.
Sub-step 3: Carefully pull the sensor out of its housing and inspect it for dirt or damage.
Sub-step 4: Clean the sensor with brake cleaner and a wire brush if necessary.
Sub-step 5: Reinstall the sensor and torque the bolts to the manufacturer's specifications.

3. Check ABS Module and Wiring

Sub-step 1: Visually inspect the ABS module for any signs of damage or corrosion.
Sub-step 2: Check the wiring and connectors for frays or corrosion; repair or replace as needed.
Sub-step 3: Reconnect any loose connections securely.

4. Verify Brake Fluid Level

Sub-step 1: Open the hood and locate the brake fluid reservoir.
Sub-step 2: Check the fluid level; if it is low, top it off with the recommended brake fluid type (DOT 3 or DOT 4).
Sub-step 3: Inspect the fluid for contamination; if dirty, consider a complete brake fluid flush.

5. Clear Error Codes

Sub-step 1: Reconnect the battery terminal.
