Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Clean Wheel Speed Sensors

Tools Required: Socket set, cleaning brush, brake cleaner.
Remove the wheel on the affected side to access the wheel speed sensor.
Visually inspect the sensor for any damage or debris.
Clean the sensor and its mounting area with brake cleaner and a brush.
Reinstall the sensor and wheel, then repeat for the other side if necessary.

3. Check and Replace ABS Fuse

Tools Required: Fuse puller or pliers.
Locate the ABS fuse in the fuse box (refer to the owner's manual for exact location).
Pull the fuse and inspect it for continuity; replace if blown with the same amperage rating.
Reinstall the fuse in the fuse box.

4. Test ABS Pump and Module

Tools Required: Multimeter.
Reconnect the battery terminal and turn the ignition key to the "On" position without starting the engine.
Use a multimeter to test the ABS pump and module for proper voltage and functionality according to the manufacturer’s specifications.
If the pump fails to engage or shows improper voltage, it may need replacement.

5. Brake Fluid Inspection

Tools Required: Brake fluid tester or gauge.
Check the brake fluid level in the master cylinder reservoir.
If low, top off with the recommended brake fluid (DOT 3 or DOT 4 as specified).
Inspect for leaks in the brake lines and around the master cylinder.

6. Replace Faulty Components

If any components (wheel speed sensors, ABS pump, or module) are found to be faulty during testing, replace them with OEM or high-quality aftermarket parts.
Follow the manufacturer's installation instructions and torque specifications during reassembly.
