Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface, and the engine is off.
Disconnect the battery (negative terminal) to ensure safety.

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 for any signs of fraying or disconnection. Repair or replace as necessary.

3. Check Brake Fluid and System

Open the hood and locate the brake fluid reservoir.
Ensure the brake fluid is at the recommended level. If low, top off with the manufacturer-recommended brake fluid (DOT 3 or DOT 4 as specified).
Inspect the brake lines for leaks or damage. Repair or replace as necessary.

4. Inspect ABS Module and Wiring

Locate the ABS module, typically found near the master cylinder.
Visually inspect the module and wiring harness for any damage.
If necessary, use a multimeter to test the electrical connections for continuity.

5. Test Traction Control Switch

Locate the traction control switch on the dashboard.
Use a multimeter to test for continuity when the switch is pressed. Replace the switch if it is faulty.

6. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any error codes stored in the system.
