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 shock or short circuits.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Retrieve and record any error codes related to the ABS system.
Note the specific codes, as they will guide the next steps in diagnosing the issue.

3. Inspect ABS Components

ABS Fuse Check
- Locate the fuse box and identify the fuse for the ABS system.
- Remove the fuse and inspect it for continuity; replace if blown.
Wheel Speed Sensor Inspection
- Lift the vehicle using a jack and secure it with jack stands.
- Remove the wheels to access the wheel speed sensors.
- Visually inspect the sensors for damage; clean any dirt or debris.
- Use a multimeter to check the sensor’s resistance according to manufacturer specifications.

4. Brake Fluid and Module Inspection

Brake Fluid Level
- Check the brake fluid reservoir; refill with the correct type of brake fluid (DOT 3 or DOT 4) if low.
ABS Module
- Inspect the ABS control module for any corrosion, particularly on electrical connectors.
- If corrosion is found, clean the connectors with an electronic cleaner and a soft brush.

5. Reassemble and Test

Reinstall the wheels and lower the vehicle.
Reconnect the battery.
Clear the error codes using the OBD-II scanner and test drive the vehicle to see if the ABS light and traction control issue have been resolved.
