Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, basic hand tools
Gather necessary tools and ensure the vehicle is parked on a level surface with the engine off.
Disconnect the negative terminal of the battery for safety.

2. Inspect Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Remove any dirt or debris from the sensors using a clean cloth.
Check the wiring harness and connectors for any signs of wear or damage.
Use a multimeter to measure the resistance of the sensors; it should fall within the manufacturer's specifications (typically around 1,000-2,000 ohms). Replace any faulty sensors.

3. Check Brake Fluid Level and System

Inspect the brake fluid reservoir to ensure it is filled to the recommended level.
Look for any visible leaks in the brake lines or around the brake calipers.
If leaks are found, replace damaged lines or components and top off the brake fluid with the manufacturer-recommended type.

4. Examine the ABS Module

Locate the ABS module, usually found near the brake master cylinder.
Inspect the module for any visible damage or corrosion.
Check the wiring connected to the ABS module for loose connections.
If necessary, re-solder or replace damaged wires.

5. Test Traction Control Switch

Locate the traction control switch on the dashboard.
Use a multimeter to ensure the switch is functioning properly when pressed (continuity should be present).
Replace the switch if it is defective.

6. Software Update

Reconnect the battery terminal.
Power on the vehicle and check the settings menu for any available software updates.
If updates are available, follow the prompts to install them.
