Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to ensure safety while working on electrical components.

2. Scan for Error Codes

Use an OBD-II scanner to read ABS-related error codes.
Document any codes found for reference when diagnosing the issue.

3. Inspect ABS Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Disconnect the sensor connector and inspect wiring for damage.
Clean any dirt or debris from the sensor and mounting area.
Reconnect the sensor and secure it properly.

4. Check Brake Fluid Level and Condition

Open the hood and locate the master cylinder reservoir.
Inspect the brake fluid level; it should be between the minimum and maximum marks.
If low, top off with the manufacturer-recommended brake fluid type (DOT 4).
Check the fluid for contamination; if dirty, flush and replace the fluid.

5. Inspect ABS Control Module

Locate the ABS control module, typically found near the brake master cylinder.
Check the module's wiring harness for loose connections or corrosion.
If necessary, replace the ABS control module based on diagnostic findings.

6. Test and Bleed Brake System

If any hydraulic leaks are found, repair or replace the affected components.
Bleed the brake system to remove any air using the appropriate procedure.
Reconnect the battery and clear any error codes from the OBD-II scanner.
