Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to prevent electrical shorts.

2. Check Brake Fluid Level

Open the hood and locate the brake master cylinder.
Inspect the brake fluid level; if low, top it off with the appropriate DOT fluid as specified in the owner's manual.

3. Inspect ABS Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Clean any dirt or debris from the sensor area with a soft cloth.
Disconnect the sensor connector and inspect for damage or corrosion.
Reconnect the sensor securely.

4. Test ABS Relay and Fuses

Locate the fuse box and find the ABS relay and fuses.
Remove the fuses and relay, then test them for continuity with a multimeter.
Replace any blown fuses or faulty relays with OEM parts.

5. Clear Codes and Test Drive

Reconnect the battery.
Use the OBD-II scanner to clear any stored ABS fault codes.
Conduct a test drive to see if the ABS light re-illuminates.

6. Replace Faulty Components

If trouble codes indicate a specific faulty sensor or component, replace it with an OEM part.
Follow manufacturer specifications for installation and torque values.
