Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, brake fluid.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical shorts.

2. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove the sensor connectors (if applicable) and inspect for damage.
Clean the sensor and the mounting area to remove dirt or debris.
Reconnect the sensors and ensure they are securely fastened.

3. Check Brake Fluid Level

Remove the cap from the brake fluid reservoir.
Inspect the fluid level; if low, top it off with manufacturer-recommended brake fluid.
Replace the cap securely after checking.

4. Test ABS Module

Reconnect the battery.
Use the OBD-II scanner to check for ABS module functionality and clear any stored codes.
If codes persist, further diagnostic testing of the ABS module may be necessary.

5. Check Traction Control Switch

Locate the traction control switch on the dashboard.
Ensure the switch is in the "ON" position; if it is stuck or malfunctioning, replace the switch.
