Stabilitrak Terminology, How to fix stabilitrak
This section defines key terms related to Stabilitrak, providing a comprehensive understanding of the system’s components and functions.
| Term | Definition |
|---|---|
| Actuators | Actuators are the components that carry out the corrective actions commanded by the Stabilitrak system. These typically include the brakes and throttle, which are manipulated to adjust vehicle speed and direction. For instance, if the system detects a skid, it might apply the brakes to individual wheels or reduce engine power to regain control. |
| Anti-Lock Braking System (ABS) | ABS is a vital component of Stabilitrak, preventing wheel lock-up during braking. By modulating brake pressure, ABS allows the driver to maintain steering control during emergency braking situations. This is essential for Stabilitrak to effectively intervene and prevent skidding. |
| Calibration | Calibration is the process of setting up the Stabilitrak system’s parameters to match the specific vehicle’s characteristics. This ensures accurate sensor readings and proper intervention thresholds. Incorrect calibration can lead to inaccurate system responses, compromising safety. |
| Electronic Stability Control (ESC) | ESC is the broader term for electronic systems designed to enhance vehicle stability and control. Stabilitrak is a specific type of ESC system developed by General Motors. While Stabilitrak incorporates features like traction control and anti-lock brakes, ESC refers to the overall concept of electronically assisted vehicle stability. |
| Fault Codes | Fault codes are diagnostic codes generated by the Stabilitrak system to indicate potential problems. These codes can be read using a scan tool and provide valuable information about the system’s malfunction. Understanding these codes is essential for diagnosing and resolving Stabilitrak issues. |
| Intervention Thresholds | Intervention thresholds define the limits beyond which the Stabilitrak system will intervene to correct a potential loss of control. These thresholds are based on various factors, including vehicle speed, steering angle, and yaw rate. The system constantly monitors these parameters and intervenes when they exceed the pre-determined thresholds. |
| Sensors | Sensors are the eyes and ears of the Stabilitrak system, providing critical data about the vehicle’s state. These sensors include:
|
| Stabilitrak | Stabilitrak is a proprietary electronic stability control (ESC) system developed by General Motors. It utilizes various sensors and actuators to detect and correct potential loss of vehicle control. By analyzing data from sensors, Stabilitrak identifies situations where the vehicle may be losing traction or heading towards a skid. The system then intervenes by applying brakes to individual wheels, reducing engine power, or both, to regain control. |
| Traction Control System (TCS) | TCS is a subsystem of Stabilitrak that prevents wheel spin during acceleration. By sensing wheel slip, TCS applies brake pressure to the slipping wheel(s) and reduces engine power to restore traction. This helps maintain control during acceleration on slippery surfaces, like snow or ice. |
| Yaw Control | Yaw control is a crucial aspect of Stabilitrak that manages the vehicle’s tendency to rotate around its vertical axis (yaw). The system monitors yaw rate and steering input, intervening when necessary to prevent oversteer or understeer. For example, if the vehicle starts to oversteer, Stabilitrak might apply brakes to the inside wheels to counteract the rotation and maintain stability. |
