Solution

1. Preparation

Gather tools and materials: OBD-II scanner, socket set, multimeter, brake fluid, cleaning supplies.
Park the vehicle on a level surface and engage the parking brake.

2. Scan for 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 note any ABS-related trouble codes.

3. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Disconnect the electrical connector and inspect for corrosion or damage.
Use a multimeter to check sensor resistance; it should typically be within the manufacturer's specified range.
Clean the sensors if they are dirty using brake cleaner and reinstall them.

4. Check ABS Fuse

Locate the fuse box, usually under the dashboard or engine bay.
Remove the ABS fuse and inspect it for continuity; replace if blown.
Reinstall the fuse securely.

5. Inspect ABS Control Module

Follow the wiring harness from the ABS module to check for loose connections or damaged wiring.
Ensure that the module is properly mounted and secure.

6. Verify Brake Fluid Condition

Open the brake fluid reservoir cap.
Check the fluid level; top off if low with the manufacturer-recommended brake fluid.
Inspect the fluid for discoloration or debris, indicating contamination.
