what does it mean if my Volkswagen Golf MK7 (2015-2019) traction control light is on

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 at each wheel hub.
• Remove any mud or debris around the sensors to ensure proper function.
• Disconnect the sensor wiring harness and visually inspect for any damage.
• Clean the sensor and connector using electrical contact cleaner before reconnecting.

3. Check Brake Fluid Level

• Open the hood and locate the brake fluid reservoir.
• Inspect the fluid level; if low, top off with the recommended brake fluid (DOT 4).
• Look for any leaks in brake lines or around the master cylinder.

4. Examine ABS Control Module

• Access the ABS control module, typically located near the brake master cylinder.
• Inspect all wiring and connectors for signs of wear or corrosion.
• If damage is found, repair or replace the wiring as necessary.

5. Test Traction Control Switch

• Locate the traction control switch on the dashboard.
• Use a multimeter to test the switch for continuity.
• If the switch is faulty, replace it.

6. Tire Inspection

• Check all tires for proper pressure, tread depth, and any visible damage.
• Inflate tires to the manufacturer's recommended pressure if necessary.
• Replace any damaged or worn tires.
