Solution

1. Preparation

Gather tools and parts needed for the repair.
Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, brake cleaner, and safety glasses.
Safety Warnings: Ensure the vehicle is on a flat surface and securely supported with jack stands. Disconnect the battery before working on electrical systems.

2. Retrieve and Analyze DTCs

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn the ignition to the ON position without starting the engine.
Record any ABS-related trouble codes and refer to the service manual for specific troubleshooting steps based on the codes.

3. Inspect and Replace Wheel Speed Sensors (if necessary)

Remove the wheel and tire assembly to access the wheel speed sensor.
Disconnect the sensor's electrical connector and remove the mounting bolt.
Inspect the sensor for damage or debris; clean or replace it as necessary.
Reinstall the new or cleaned sensor, ensuring it is securely mounted and connected.

4. Check and Repair ABS Module Connections

Locate the ABS control module and disconnect the electrical connector.
Inspect for corrosion or loose connections; clean terminals if necessary.
Reconnect the module securely and ensure no wires are pinched or damaged.

5. Verify Brake Fluid Level

Open the brake fluid reservoir cap and check the fluid level.
If the fluid is low, top it off with the manufacturer-recommended brake fluid.
Replace the cap and ensure it is secure.
