Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety while working on the electrical system.

2. Check and Replace Fuses

Locate the fuse box; refer to the owner’s manual for the specific location of the ABS fuses.
Remove the fuse and inspect it for any signs of damage or burnout.
Replace any blown fuses with new ones of the same amperage.

3. Inspect and Clean Wheel Speed Sensors

Raise the vehicle securely using jack stands.
Locate the wheel speed sensors at each wheel hub.
Disconnect the electrical connector from the sensor.
Clean the sensor and mounting area with a soft cloth to remove any dirt or debris.
Reconnect the sensor and ensure it is securely mounted.

4. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Check the fluid level; if below the minimum line, top it off with the manufacturer-recommended brake fluid.
Inspect for any signs of leaks around the reservoir and brake lines.

5. Inspect ABS Module and Wiring

Locate the ABS module, typically found near the master cylinder.
Visually inspect the module and wiring for any signs of damage or corrosion.
If necessary, test the module with a multimeter to check for proper voltage and ground.

6. Clear Error Codes and Test Drive

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any error codes.
Conduct a test drive to ensure the ABS light does not reappear and the braking system functions correctly.
