Solution

1. Preparation

Gather tools and parts required.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Clean any dirt or debris from the sensors using a soft cloth.
Check the wiring harness for any signs of wear or damage.
If damaged, replace the wheel speed sensor with a new one.

3. Check Brake Fluid Level

Locate the brake fluid reservoir in the engine compartment.
Inspect the fluid level, ensuring it is within the recommended range.
If low, top off with the appropriate brake fluid type (DOT 3 or DOT 4).
If the fluid is contaminated, perform a brake fluid flush and replace with fresh fluid.

4. Test ABS Module

Reconnect the battery terminal.
Use the OBD-II scanner to check for ABS module communication.
If communication fails, inspect the wiring and connectors to the ABS module for loose connections.
If necessary, replace the ABS module.

5. Inspect Traction Control Switch

Locate the traction control switch on the dashboard.
Test the switch operation by toggling it on and off.
If the switch is not functioning correctly, replace it with a new switch.
