Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical short circuits.

2. Retrieve Error Codes

Connect an OBD-II scanner to the vehicle's diagnostic port.
Turn on the ignition without starting the engine.
Retrieve and record any ABS-related error codes for further analysis.

3. Inspect Wheel Speed Sensors

Locate each wheel speed sensor near the brake assembly.
Disconnect the electrical connector from each sensor.
Inspect the wiring for frays or breaks.
Clean the sensor and the mounting area to ensure proper function.
Reconnect the sensors and ensure they are securely fastened.

4. Check ABS Module and Fuse

Locate the ABS module, often found near the master cylinder.
Inspect for any visible damage or leaks.
Check the ABS fuse located in the fuse box; replace if blown.
If necessary, consult the owner's manual for the fuse location and specifications.

5. Brake Fluid Inspection

Open the hood and locate the brake fluid reservoir.
Check the fluid level and condition; top off with the appropriate brake fluid type if low.
If the fluid is contaminated, perform a brake fluid flush.

6. Test Drive

Reconnect the negative battery terminal.
Start the vehicle and perform a test drive to see if the ABS light remains off.
Monitor braking performance and ensure no unusual noises or behaviors are present.
