How Does StabiliTrak Work?
The StabiliTrak automatic traction control system uses sensors to monitor the driver’s inputs and the vehicle’s movement and then applies selective braking and throttle control to help the driver maintain control of the vehicle.
StabiliTrak comprises several components, including sensors, a computer module, and an actuator. Sensors determine the direction and rotation of the vehicle’s wheels. Then the computer module determines if the car is going in the desired direction.
Suppose the computer module detects that the vehicle is not going in the intended direction. To help bring the car back on track, a signal is sent to the actuator, which applies brakes to one or more wheels or reduces the engine’s power.
Furthermore, StabiliTrak can be used in conjunction with the traction control system to offer improved grip in slippery conditions. When StabiliTrak detects a wheel slipping. To maximize traction and grip, it reduces engine power and applies brakes.
StabiliTrak has different names for different vehicles. For instance, in BMW cars, it is known as Dynamic Stability Control (DSC), while in Honda, it’s known as Vehicle Stability Assist (VSA). Whatever the name is, the purpose is the same, to control the stability and traction of the cars.
What Type of Sensors Does StabiliTrak Use?
The service stability system uses several sensors to monitor the vehicle’s movement and the driver’s inputs. Here goes the list of the sensors.
- Steering Wheel Angle Sensor: This sensor detects the steering wheel’s position and rotation rate. It also uses this information to determine the driver’s intended direction of travel.
- Yaw Rate Sensor: It detects the vehicle’s rotation around its vertical axis and uses this information to determine the vehicle’s actual direction of travel.
- Lateral Accelerometer: Lateral accelerometer detects the side-to-side acceleration of the vehicle and uses this information to determine whether the vehicle is sliding or spinning.
- Wheel Speed Sensors: This particular sensor detects the rotational speed of each wheel and uses this information to determine whether the vehicle is oversteering, understeering or if there’s a wheel losing traction
- Throttle Position Sensor: It measures the position of the throttle and how much power the engine is delivering to the wheels.
Summary:StabiliTrak comprises sensors, a computer module, and an actuator. The actuator applies brakes to one or more wheels or reduces the engine’s power to help the car get back on track.
StabiliTrak: What Causes the Light to Come On?
There are several reasons why the “Service Stabilitrak” warning light may come on in a vehicle equipped with the StabiliTrak system. Here are a few common reasons for what causes StabiliTrak.
Reason 1: Faulty Input/Output Sensor
The input and output sensors are responsible for receiving the critical data from traction control. The data then gets delivered to the ECU and ABS braking systems. The StabiliTrak warning light comes on When one of these sensors malfunctions.
Reason 2: Faulty Power Steering Sensor
The Vehicle Stability Control Module receives information from the power steering sensor and input sensor about how much assistance is being provided by the power steering system while driving. The sensor would not be able to communicate the level of assistance to the vehicle if it malfunctioned.
Reason 3: Stability Control Module Problems
All vehicle systems are monitored by the Stability Control Module to ensure the vehicle stays stable on the road. As a result, If the controller malfunctions, it may not be able to accurately monitor the car’s systems.
Reason 4: ABS System Malfunction
The StabiliTrak system controls the ABS modules to adjust brakes when the car is out of control automatically. In case of a malfunction of the ABS Module, it may be unable to properly control the brake system, leading to potential loss of control over the vehicle.
Reason 5: Bad or Faulty Connection
When a GM-LAN communication line is damaged, the Service StabiliTrak warning light illuminates. The GM-LAN communication line is a bundle of wires encased in plastic and runs toward the transmission.
To safeguard the wiring and transmission parts, a heat shield is securely attached to the transmission. A break in the communication line can cause the warning light to activate.
Reason 6: SCM Module Inconsistency
The SCM module controls the vehicle’s stability and traction control system. It automatically controls all the sensors and the data to improve the stability and traction of the vehicle in extreme driving situations. If the module malfunctions, the service stabiliTrak message will appear. Expert diagnosis and an immediate fix are a must.
Summary:The “Service Stabilitrak” warning light may come on due to issues with sensors, the stability control module, the ABS system, or communication lines.
