Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely supported.
Disconnect the negative battery terminal to prevent electrical issues.

2. Inspect and Replace Wheel Speed Sensors

Locate the Wheel Speed Sensors: Remove the wheel and brake assembly to access the sensors.
Disconnect the Sensor Connector: Unplug the electrical connector from the wheel speed sensor.
Remove the Sensor: Unscrew the sensor from its mounting point using a socket set.
Inspect the Sensor: Check for physical damage or excessive wear. Clean any debris or dirt from the mounting area.
Install New Sensor (if necessary): Place the new sensor in position and tighten it to the manufacturer’s torque specification (usually around 7-10 lb-ft).
Reconnect the Sensor Connector: Ensure the electrical connector is securely attached.

3. Check and Refill Brake Fluid

Locate the Brake Fluid Reservoir: Open the hood and find the brake fluid reservoir.
Check Fluid Level: Inspect the fluid level; if low, clean the reservoir cap and top off with the manufacturer-recommended brake fluid (usually DOT 3 or DOT 4).
Replace Cap: Securely close the reservoir cap.

4. Inspect the ABS Module

Locate the ABS Module: Usually found near the master cylinder or under the driver's side dashboard.
Check Connections: Ensure all electrical connectors to the ABS module are secure and free of corrosion.
Scan for Codes Again: If previous codes were found, clear them and check if the light returns after reassembly.

5. Reconnect Battery

Reattach the negative battery terminal and ensure it is tight.
