What is the code for car spin?

Car spin refers to an uncontrolled skid caused by excessive speed exiting a corner or insufficient tire grip. When a moving vehicle experiences lateral movement (sideways sliding) of one or both axles due to braking, rotational inertia, or other factors, this phenomenon is called a skid. Below is relevant information: Types of car skids: There are three types - four-wheel skid, front-wheel skid, and rear-wheel skid. Car skids, especially rear-wheel skids, pose significant threats to driving safety and often lead to severe traffic accidents such as collisions, rollovers, or roadside ditch crashes. According to statistics from a certain Chinese province regarding fatal traffic accidents where drivers bore primary responsibility, 40% were caused by rear-wheel skids, with 50% of these occurring during braking and turning maneuvers - highlighting the need for heightened awareness. Specific causes: Reasons for car skids include slippery road surfaces (wet, oily, or icy conditions) that reduce friction coefficients asymmetrically, decreasing wheel load and road adhesion. Even slight lateral forces can trigger wheel skids. Additionally, imbalanced braking resistance across wheels (uneven braking force between left/right wheels, varying friction coefficients, or uneven load distribution) can cause pulling and frequently lead to wheel skidding.
Last time when I took a sharp turn on a slippery road, the SPIN yellow light suddenly flashed on the dashboard. After the wheels briefly skidded, the car body was immediately pulled back. This SPIN actually indicates that the traction control system is working. When the car detects a wheel spinning, it automatically activates the assistance system, braking the skidding wheel while reducing engine power output. I specifically looked it up – most mainstream models' ESP systems now have this feature, which is like having an invisible hand helping the driver stabilize the direction. It's important to note that SPIN is not a fault code but a safety reminder.
Our rally racing modification friends often discuss this. SPIN essentially represents the critical state where the tires exceed the friction limit, professionally referred to as the 'slip rate value.' The SPIN warning that regular drivers see on the dashboard is actually a user-friendly expression by the ESP system when it detects danger. The key point is that when the system intervenes, you must avoid slamming on the brakes or steering erratically. The correct approach is to hold the steering wheel steady and ease off the throttle. I’ve heard that drivers in northern snowy regions see this warning light flash several times a week during winter.
