Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.

2. Inspect ABS Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Clean any dirt or debris from the sensors using a soft cloth.
Check the sensor wiring for frays, breaks, or loose connections and repair as needed.
Reconnect the connectors securely.

3. Check ABS Fuse

Locate the fuse box and identify the ABS fuse using the owner's manual.
Remove the fuse and inspect for continuity using a multimeter.
If the fuse is blown, replace it with a fuse of the same amperage rating.

4. Brake Fluid Inspection

Check the brake fluid reservoir for proper fluid level.
If low, top off with the recommended brake fluid type (usually DOT 3 or DOT 4).
Inspect the fluid for discoloration or contamination; if contaminated, perform a brake fluid flush and replace.

5. Verify ABS Module

If diagnostic codes indicate an ABS module issue, perform a thorough inspection of the module and its connections.
If necessary, replace the ABS module following manufacturer specifications.
Reconnect the negative battery terminal after all checks and repairs are complete.
