Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative terminal of the battery to ensure safety.

2. Check and Replace ABS Fuse

Locate the fuse box according to the owner’s manual.
Remove the ABS fuse using a fuse puller or pliers.
Inspect the fuse visually and with a multimeter for continuity.
Replace with a new fuse of the same amperage if blown.

3. Inspect and Clean Wheel Speed Sensors

Raise the vehicle safely and support it with jack stands.
Remove the wheels to access the brake components.
Locate the wheel speed sensors at each wheel hub.
Disconnect the sensor harness and inspect for dirt or damage.
Clean the sensor with brake cleaner and a soft cloth; reattach.

4. Check Brake Fluid Level

Locate the brake fluid reservoir under the hood.
Ensure the fluid level is between the minimum and maximum marks.
If low, top off with the manufacturer-recommended brake fluid type (DOT 3 or DOT 4).
Recheck for any leaks in the brake lines or connections.

5. Inspect ABS Control Module and Wiring

Visually inspect the ABS control module for any signs of damage or corrosion.
Check wiring harnesses connected to the module for frays or disconnections.
If any damage is found, repair or replace the affected components.

6. Test ABS Pump

Reconnect the battery and turn on the ignition without starting the engine.
Listen for the ABS pump to activate; it should make a humming sound.
If there is no activation, further diagnostics may be needed on the pump or module.
