The traction control system relies on wheel speed sensors to determine if one or more wheels are slipping. When new tires are installed, it's possible that one of the wheel speed sensors may have been damaged or disconnected accidentally during the tire replacement process. If a sensor is faulty or not properly connected, it could trigger the TCS light.
Tire Size Discrepancy: If the new tires have a significantly different size or diameter compared to the old ones, it could confuse the traction control system. Modern vehicles with traction control systems rely on precise wheel speed measurements, and a significant difference in tire size could lead to inaccurate readings.
Tire Pressure: Ensure that the tire pressures are set to the manufacturer's recommended specifications. Incorrect tire pressure can affect the wheel speed readings and trigger the TCS light.
Faulty Traction Control System: While less common, it's also possible that there's a fault within the traction control system itself. This could be due to a malfunctioning control module or other internal components.
Since the ABS light hasn't come on and the car drives normally, it suggests that the issue might not be related to a major malfunction in the traction control system. However, it's still important to have the vehicle inspected to diagnose the exact cause of the TCS light staying on.
