Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to prevent electrical shorts.

2. Check ABS Fuses

Locate the fuse box and find the ABS fuse.
Remove the fuse and inspect it for continuity.
Replace with the same amperage fuse if blown.

3. Inspect Wheel Speed Sensors

Lift the vehicle and secure it on jack stands.
Locate and visually inspect each wheel speed sensor for dirt or physical damage.
Clean the sensors using a soft cloth; replace any damaged sensors.

4. Check Brake Fluid Level

Open the brake fluid reservoir cap.
Inspect fluid level; top up with manufacturer-recommended brake fluid if low.
Replace the cap securely.

5. Inspect Wiring and Connectors

Check the wiring harness connected to the ABS module for signs of wear or damage.
Clean any corrosion on connectors with electrical contact cleaner.
Ensure all connections are secure.

6. Test ABS Module

Reconnect the battery.
Use the OBD-II scanner to initiate a self-test of the ABS system.
Ensure the module activates correctly and check for any new error codes.
