Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a level surface, and engage the parking brake.
Disconnect the negative terminal of the battery to prevent accidental electrical shorts.

2. Address Fault Codes

Reconnect the battery and turn the ignition to the "ON" position (do not start the engine).
Use the OBD-II scanner to clear any previously stored ABS trouble codes.
If codes return after clearing, proceed with further diagnostics based on the specific codes.

3. Inspect and Replace Wheel Speed Sensors

Tools Required: Socket set, torque wrench, multimeter.
Locate the wheel speed sensors at each wheel hub.
Disconnect the sensor connector and inspect for corrosion or damage.
Use a multimeter to test the sensor resistance; replace if out of specifications.
Reinstall the new sensor and torque the bolts to the manufacturer’s specification.

4. Check and Replace ABS Fuse

Locate the fuse box in the engine compartment or cabin, as indicated in the owner’s manual.
Remove the ABS fuse and check for continuity using a multimeter.
Replace the fuse if blown, ensuring it meets the required amperage.

5. Inspect ABS Module and Wiring

Visually inspect the ABS module mounted near the master cylinder.
Check the wiring harness for signs of wear, fraying, or corrosion.
Repair or replace damaged wiring as necessary.
Reconnect all electrical connections securely.

6. Brake Fluid Inspection

Check the brake fluid reservoir for proper fluid level.
If the fluid is low, top it off with the manufacturer's recommended brake fluid type.
Inspect for any leaks in the brake lines or around the master cylinder.
