Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, basic hand tools, torque wrench.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn the ignition to the ON position without starting the engine.
Retrieve and note any ABS-related error codes for further analysis.

3. Inspect Wheel Speed Sensors

Locate the ABS wheel speed sensors at each wheel hub.
Clean any debris or dirt from the sensor and its mounting area.
Check the wiring harness connected to each sensor for damage or wear.
If any sensors are damaged, replace them with OEM-spec parts.

4. Check ABS Control Module

Locate the ABS control module, usually found near the master cylinder.
Inspect for any physical damage, corrosion, or loose connections.
If the module is faulty, replace it as per the manufacturer’s specifications.

5. Check Brake Fluid Level and System

Open the hood and locate the brake fluid reservoir.
Ensure the brake fluid is at the recommended level; top up as needed with the specified brake fluid type.
Inspect for any leaks in brake lines or at the calipers, repairing as necessary.

6. Reconnect Battery and Clear Codes

Reconnect the battery after repairs are completed.
Use the OBD-II scanner to clear any stored ABS codes.
Turn off the ignition and then restart the vehicle to ensure the ABS light is off.
