Those who drive a Chevrolet Silverado are likely familiar with the StabiliTrak feature. It monitors each wheel’s speed and helps maintain the truck’s stability by regulating the braking pressure and engine torque. If the system fails, however, the Service StabiliTrak alert will activate.
Wheel speed sensors are the most common cause of StabiliTrak failure. As the sensors are exposed to road debris and dirt, they can become blocked, rusted, or otherwise compromised. This can result in the sensors sending erroneous data to the system, triggering the Service StabiliTrak alert.
Thankfully, repairing StabiliTrak is extremely simple. First, look for evidence of damage, corrosion, or clogging on the wheel speed sensors. If any of the sensors are broken, they must be replaced.
The following step is to verify that the wiring and connectors are in good condition. If any of the wire is frayed or disconnected, it will need to be replaced.
Once the wheel speed sensors and wiring are in good condition, the system should be reset. Turn the key to the “on” position and hold the StabiliTrak button for 10 seconds. This should reset the system and disable the indicator light.
You should be able to restore functionality to your Silverado’s StabiliTrak system by thoroughly inspecting and replacing any damaged components.
