Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to avoid electrical shock.

2. Inspect the ABS Fuses

Locate the fuse box, usually under the dashboard or in the engine compartment.
Remove the ABS fuse and check for continuity using a multimeter.
If the fuse is blown, replace it with a fuse of the same amperage.

3. Check Wheel Speed Sensors

Lift the vehicle using a jack and secure it on jack stands.
Access each wheel and locate the ABS wheel speed sensor.
Inspect the sensor for physical damage and ensure it is securely mounted.
Disconnect the sensor connector and check for any corrosion or dirt.
Use a multimeter to test the sensor's resistance; it should be within the manufacturer's specifications.

4. Inspect Wiring and Connectors

Visually inspect the wiring harness connected to the ABS module for any signs of wear or damage.
Check connectors for corrosion or poor connections.
Repair or replace any damaged wiring or connectors as needed.

5. Test the ABS Module and Pump

Reconnect the battery and use a scan tool to activate the ABS module.
Listen for the operation of the ABS pump; it should activate briefly when the ignition is turned on.
If the pump does not operate, further testing of the module's power supply and ground connections may be necessary.

6. Top Off Brake Fluid

Check the brake fluid reservoir; if low, top it off with the manufacturer's recommended brake fluid.
Inspect for any leaks in the brake system that could cause fluid loss.
