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 shock.

2. Check and Replace Fuses

Tools Required: Fuse puller or pliers.
Locate the fuse box (typically under the dashboard or in the engine compartment).
Identify the ABS fuse using the fuse diagram.
Remove the ABS fuse and inspect it for damage; replace if blown.

3. Inspect and Clean Wheel Speed Sensors

Tools Required: Socket set, cleaning brush or cloth.
Lift the vehicle using a jack and secure it on jack stands.
Remove the wheel to access the wheel speed sensor.
Inspect the sensor for dirt or debris; clean if necessary.
Check the sensor’s wiring for damage and reconnect any loose connections.
Repeat for all four wheels.

4. Refill Brake Fluid

Tools Required: Brake fluid (DOT 3 or as specified in the owner’s manual).
Locate the master cylinder reservoir.
If the brake fluid level is low, remove the cap and carefully add brake fluid to the recommended level.
Replace the cap securely.

5. Test ABS Module

Tools Required: Multimeter.
Reconnect the battery terminal.
Use a multimeter to check the voltage at the ABS module connector while the vehicle is running.
If voltage is absent, further diagnose wiring issues or consider module replacement.
