When the TC light appears on the car dashboard, it indicates that the traction control system is either turned off or malfunctioning. TC stands for Traction Control, a system designed to enhance vehicle mobility. When the ABS (Anti-lock Braking System) detects wheel slippage, it applies brakes to the slipping wheel to prevent loss of traction. During operation, the yellow TC indicator on the dashboard will flash to alert the driver. The traction control system uses electronic sensors to detect when a driven wheel's speed is lower than the driving wheels. Upon detecting this, it sends signals to adjust ignition timing, reduce throttle opening, decrease acceleration, downshift, or apply wheel braking to prevent further slippage. This system significantly improves driving stability and climbing capability.

What procedures are required for car wrap color change?

The "Motor Vehicle Change Registration Application Form", identity proofs and copies of the motor vehicle owner and agent, the motor vehicle registration certificate, the motor vehicle driving license, and payment of all previous fines are the procedures required to apply for a change in the body color of a motor vehicle. According to Article 6 of Chapter 2 of the "Road Traffic Safety Law", if the color change area of a motor vehicle does not exceed 30%, there is no need to go through the change registration process. Conversely, if it exceeds 30%, it must be filed and registered within 10 days after the vehicle color change. Precautions for vehicle wrap color change: Before preparing to change the color of a vehicle wrap, it is necessary to consult the vehicle management office where the vehicle is registered to confirm whether the region allows motor vehicles to change color using wraps. If the region does not support this method, it will be impossible to complete the filing procedures after the color change, and the only option will be to remove the wrap entirely and restore the vehicle's original color. Additionally, according to Article 10 of the "Motor Vehicle Registration Regulations": Owners are no longer required to apply to the vehicle management office in advance. They can first change the vehicle color, install body kits, replace the engine, etc., and then apply to the vehicle management office for change registration. Furthermore, registered motor vehicles must apply for change registration under the following circumstances: Change of body color. Replacement of the engine. Replacement of the body or frame. Replacement of the entire vehicle due to quality issues. Change of use nature, such as converting a commercial motor vehicle to a non-commercial one or vice versa. The motor vehicle owner's residence moves out of or into the jurisdiction of the vehicle management office. In addition, according to Article 15 of the "Road Traffic Safety Law of the People's Republic of China": Police cars, fire trucks, ambulances, and engineering rescue vehicles must spray emblem patterns and install alarms and signal lights as required. Other motor vehicles are not allowed to spray, install, or use emblem patterns, alarms, or signal lights that are specific to the aforementioned vehicles or similar to them.
