Solution

1. Preparation

Gather tools and materials: OBD-II scanner, multimeter, socket set, brake fluid, cleaning supplies.
Ensure the vehicle is parked on a level surface with the engine off and the keys removed from the ignition.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "On" position without starting the engine.
Retrieve and record any ABS-related error codes.

3. Inspect ABS Components

ABS Wheel Speed Sensors:
- Remove the wheel corresponding to any faulty speed sensor indicated by the error codes.
- Inspect the sensor for physical damage or dirt; clean if necessary.
- Use a multimeter to check the resistance of the sensor, ensuring it falls within manufacturer specifications.
Wiring and Connectors:
- Visually inspect the wiring harness for fraying or corrosion.
- Ensure all connectors are firmly seated and free of corrosion.

4. Brake Fluid Check

Locate the brake fluid reservoir and check the fluid level.
If the fluid is low, top it off with the recommended brake fluid type (DOT 3 or DOT 4).
If the fluid appears contaminated, flush the brake system and refill with fresh brake fluid.

5. ABS Module Inspection

Access the ABS module, usually located near the master cylinder.
Check for any visible signs of damage or leaks.
If the module is faulty, replace it with a new unit following manufacturer specifications.

6. Test and Clear Codes

After repairs, reconnect any components removed.
Use the OBD-II scanner to clear any stored error codes.
Start the engine and observe if the ABS light turns off.
