Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to avoid any electrical shorts.
Ensure the vehicle is on a level surface and securely raised with jack stands if needed.

2. Inspect and Replace Wheel Speed Sensors

Tools Required: Socket set, multimeter, cleaning brush.
Locate the wheel speed sensors at each wheel hub.
Disconnect the electrical connector of each sensor.
Remove the sensor using a socket.
Clean any debris around the sensor mounting area.
Inspect the sensor for damage or wear; replace if necessary.
Reinstall the sensor and reconnect the electrical connector.

3. Check and Refill Brake Fluid

Tools Required: Brake fluid (DOT 3 or DOT 4 as specified in the owner’s manual), funnel.
Open the hood and locate the master cylinder reservoir.
Check the brake fluid level; if low, clean the area around the cap and remove it.
Using a funnel, add the appropriate brake fluid until the level reaches the "full" mark.
Replace the cap securely.

4. Inspect ABS Control Module and Wiring

Tools Required: Basic hand tools, multimeter.
Locate the ABS control module, typically found near the brake master cylinder.
Visually inspect the module and wiring for any signs of damage or corrosion.
Use a multimeter to test the voltage and ground at the ABS module connections.
Repair or replace any damaged wiring or connectors.

5. Reconnect Battery and Clear Codes

Reconnect the battery terminals securely.
Use the OBD-II scanner to clear any stored ABS codes.
Ensure the ABS warning light is off after clearing.
