Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Retrieve and Address Fault Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Retrieve and document any ABS-related fault codes.
Clear the codes and see if they reappear after a test drive.

3. Inspect Wheel Speed Sensors

Raise the vehicle and remove the front and rear wheels as needed.
Locate the wheel speed sensors and visually inspect for cracks or dirt.
Use a multimeter to check the resistance of each sensor (typically 1,000-2,000 ohms).
Clean any debris from the sensor area and check the wiring harness for damage.

4. Check ABS Fuse and Relay

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the ABS fuse and inspect it for continuity.
If the fuse is blown, replace it with the same amperage.
Test the ABS relay by swapping it with another relay of the same specifications.

5. Inspect ABS Control Module

Locate the ABS control module, typically near the master cylinder.
Check all connectors for corrosion, dirt, or loose connections.
Clean any corrosion with electrical contact cleaner and resecure connections.

6. Brake Fluid and System Check

Check the brake fluid level; top off with the recommended DOT fluid if low.
Inspect the brake lines for leaks or physical damage.
If leaks are found, replace the affected brake lines.

7. Reassemble and Test

Reattach the wheels and lower the vehicle.
Reconnect the negative battery terminal.
Start the vehicle and perform a test drive to ensure the ABS light does not reappear.
