Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, and the ignition is off.
Disconnect the negative battery terminal for safety.

2. Retrieve and Analyze Diagnostic Codes

Use an OBD-II scanner to retrieve any ABS-related error codes.
Record the codes and refer to a service manual to determine potential issues related to the codes.

3. Inspect ABS Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Clean the sensors and their mounting areas with a brake cleaner to remove dirt or debris.
Check the sensor connectors for tightness and signs of corrosion.
If damaged, replace the wheel speed sensor with a new one.

4. Check and Replace Fuses

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the ABS fuse using the diagram on the fuse box cover.
Use a multimeter to test the fuse for continuity; replace if necessary.

5. Brake Fluid Inspection

Check the brake fluid reservoir for proper fluid level.
If low, add the appropriate DOT fluid as specified in the owner’s manual.
If the fluid is discolored or contaminated, perform a brake fluid flush.

6. Reconnect and Reset

Reconnect the negative battery terminal after completing repairs.
Use the OBD-II scanner to clear any codes and reset the ABS light.
Start the vehicle and test the ABS and traction control lights.
