Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors on each wheel.
Remove the sensor's connector and inspect for corrosion or damage.
Clean the sensor and the mounting area with electrical contact cleaner.
Reconnect the sensor and ensure it is securely mounted.

3. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Inspect the fluid level; it should be between the MIN and MAX marks.
If low, top off with the recommended brake fluid type (DOT 3 or DOT 4).
Inspect for any leaks in brake lines or at the calipers.

4. Test ABS Module

Reconnect the battery and use an OBD-II scanner to check for ABS module codes.
If codes indicate a malfunction, check wiring and connections leading to the ABS module.
If necessary, replace the ABS module according to manufacturer specifications.

5. Functionality of Traction Control Switch

Locate the traction control switch, typically found on the dashboard.
Remove the switch and check for continuity using a multimeter.
If the switch is faulty, replace it with a new one.
