Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and turn off the ignition.
Disconnect the negative terminal of the battery to prevent electrical short circuits.

2. Inspect and Replace ABS Fuse

Locate the fuse box; refer to the owner’s manual for the specific location of the ABS fuse.
Remove the ABS fuse and inspect it for continuity. If blown, replace it with a fuse of the same amperage.
Reinstall the fuse and reconnect the battery.

3. Check and Clean Wheel Speed Sensors

Lift the vehicle using a jack and secure it with jack stands.
Locate the ABS wheel speed sensors on each wheel hub.
Disconnect the electrical connector and visually inspect the sensor and wiring for damage.
Clean the sensor mount area and the sensor using a brake cleaner, and reattach the connector securely.

4. Inspect Brake Fluid

Open the hood and locate the brake fluid reservoir.
Check the brake fluid level; if low, top it off with manufacturer-recommended brake fluid.
If the fluid appears contaminated (dark or debris present), perform a brake fluid flush and replace it.

5. Test ABS Module

Reconnect the battery and turn on the ignition without starting the engine.
Use a diagnostic tool to check for any remaining error codes related to the ABS.
If codes persist, consider testing the ABS module functionality or replacing it if it is found to be defective.
