why does my Genesis G70 traction control light keep coming on

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is turned off.
• Disconnect the battery to prevent electrical shorts.

2. Check Wheel Speed Sensors

• Tools Required: OBD-II scanner, multimeter
• Remove the wheels to access the wheel speed sensors.
• Inspect each sensor for dirt or damage.
• Test each sensor's resistance with a multimeter; compare readings to manufacturer specifications.
• Clean or replace any faulty sensors.

3. Inspect Brake System

• Tools Required: Brake fluid tester, socket set
• Check the brake fluid reservoir for adequate fluid levels.
• Inspect brake lines and connections for leaks.
• If low fluid is detected, refill with the manufacturer-recommended brake fluid.
• Inspect ABS components for any visible damage or malfunction.

4. Verify Wiring and Connectors

• Tools Required: Wire brush, dielectric grease
• Examine wiring harnesses connected to the traction control system and wheel speed sensors.
• Clean any corrosion from connectors using a wire brush.
• Apply dielectric grease to connectors to prevent future corrosion.

5. Test Traction Control Switch

• Tools Required: Multimeter
• Locate the traction control switch in the cabin.
• Use a multimeter to test for continuity when the switch is activated.
• Replace the switch if it does not function properly.

6. Inspect Tires

• Check all tires for proper inflation and tread wear.
• Ensure that all tires are of the same brand and type.
• Replace any worn or mismatched tires to maintain consistent traction.
