Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, torque wrench, brake fluid, and electrical cleaner.
Disconnect the battery by removing the negative terminal to ensure safety.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove the screws or bolts securing the sensors and gently pull them out.
Clean the sensors with electrical cleaner to remove dirt and debris.
Reinstall the sensors securely and torque to manufacturer specifications.

3. Check and Replace ABS Fuse

Locate the fuse box in the engine compartment or cabin as per the owner’s manual.
Remove the ABS fuse and inspect it for damage.
If blown, replace it with a new fuse of the same amperage.

4. Inspect Wiring and Connectors

Visually inspect the wiring harness connected to the ABS module and wheel speed sensors.
Look for frayed wires, corrosion, or loose connections.
Repair or replace any damaged wiring or connectors as needed.

5. Test ABS Module and Pump

Reconnect the battery.
Use a multimeter to check for proper voltage at the ABS module.
Activate the ABS system by performing a brake test and monitoring the pump operation using the OBD-II scanner.

6. Refill Brake Fluid if Necessary

If the brake fluid level is low, add the recommended type of brake fluid (DOT 3 or DOT 4, as specified in the owner's manual).
Bleed the brakes if air is present in the system.
