Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to prevent any electrical shorts.

2. Inspect ABS Wheel Speed Sensors

Remove the wheel to access the ABS sensor.
Clean the sensor and the area around it to ensure no debris is present.
Check the sensor's connector for corrosion or loose connections.
Reinstall the wheel and lower the vehicle.

3. Check Brake Fluid Level

Open the master cylinder reservoir cap.
Visually inspect the brake fluid level; it should be within the recommended range.
If low, top off with the manufacturer-recommended brake fluid type (DOT 3 or DOT 4).
Replace the cap securely.

4. Inspect Wiring and Connectors

Trace the wiring from the ABS sensors to the ABS control module.
Look for any signs of fraying, corrosion, or damage.
Repair or replace any damaged wiring as necessary.

5. Test ABS Pump and Relay

Locate the ABS pump and relay in the fuse box.
Use a multimeter to check for proper voltage at the relay while activating the ABS system.
If the pump is faulty, replace it with a new unit following manufacturer specifications.

6. Clear Codes and Recheck

Reconnect the battery.
Use the OBD-II scanner to clear any stored ABS trouble codes.
Perform a test drive to ensure the ABS light is off and traction control is functioning properly.
