How to Reset the Service StabiliTrak Light in a GMC

If you’re reading this article, you’ve likely asked yourself recently, “Why is my StabiliTrak and traction control light on?” Warning lights are your vehicle’s way of alerting you when something is amiss with its stability or traction control systems. While the underlying issue might be as simple as a minor software glitch, you could have a more serious problem with your vehicle’s sensors or modules. In this article, we’ll explain what you can do to troubleshoot and reset your StabiliTrak system to resolve simple malfunctions before bringing your vehicle in for a professional evaluation.

What Is StabiliTrak in GMC Vehicles?

StabiliTrak is GM’s proprietary electronic stability control system that protects drivers and passengers in challenging weather and road conditions. This system works with the traction control system to prevent wheel slippage, correct understeering or oversteering, and help drivers maintain control in low-traction scenarios, such as wet, icy, or uneven roads. StabiliTrak monitors your vehicle’s movement using sensors that track steering angle, wheel speed, and direction.

When a discrepancy between the driver’s intended path and the vehicle’s actual motion is detected, the system either reduces the engine’s power or applies braking force to each wheel individually. This realigns the vehicle and reduces the risk of skidding or fishtailing. The StabiliTrak system is standard in many GMC models, including newer versions of the Sierra, Yukon, Denali, and Acadia.

Common GMC StabiliTrak Issues

The StabiliTrak system is a wonderful safety feature when it works. However, like any other advanced part of your GMC vehicle, it can malfunction. If you see a “Service StabiliTrak” warning on your dashboard, it’s important to address it promptly. Here are some common issues to be aware of so you can troubleshoot:

• Difficulty engaging or disengaging StabiliTrak: Difficulty activating or deactivating the StabiliTrak system could indicate a faulty switch or malfunction in the system’s electronic components.
• Impaired cruise control functionality: StabiliTrak and cruise control share many sensors and components, so issues within the system can interfere with cruise control performance, causing it to fail to activate or function correctly.
• Problems with traction control system activation: Traction control warnings may appear on the dashboard, or the system might not operate as expected. The StabiliTrak system works with the traction control system, so sensor or module malfunctions in one can affect the other.
• Loss of ABS efficiency: StabiliTrak relies on ABS sensors and modules to function correctly, so malfunctions in these components can compromise both systems.

Neglecting service StabiliTrak warnings can lead to decreased vehicle stability, impaired braking performance, and potential safety hazards. If you’re experiencing any of these problems, schedule a GMC service for a StabiliTrak reset. Request a diagnostic appointment with our service center today, and we’ll help you uncover and repair the issue.

How To Reset the StabiliTrak System on a GMC

Resetting the StabiliTrak system on your GMC vehicle is a straightforward process that often addresses minor glitches and clears error messages. However, before attempting a reset, verify the cause of the warning light and take the necessary safety precautions. Before proceeding, address all potential system issues, such as low brake fluid, incorrect tire pressure, and faulty wiring. Here’s a step-by-step guide on how to reset the StabiliTrak on a GMC Sierra using the manual reset process:

1. Put your GMC vehicle in park and turn off the engine.
2. Turn the steering wheel fully clockwise, then fully counterclockwise.
3. Wait 15 seconds, then restart the vehicle.
4. Disconnect the battery if the warning persists.

If you have tried the manual reset process as instructed above and the Service StabiliTrak light still comes on, you can try the battery disconnect method:

1. Locate the battery under the hood.
2. Using a wrench or pliers, carefully disconnect the negative terminal. Always begin with the negative terminal to avoid electrical mishaps.
3. Wait 10 minutes to allow the residual electrical charge to dissipate.
4. Reconnect the terminal securely, then restart the vehicle. The system should perform a self-check and clear the warning if no underlying issues remain.

For a more precise reset, use an on-board diagnostics scanner compatible with GMC vehicles. Connect the scanner to your vehicle’s on-board diagnostics port, usually under the dashboard. Then, follow the scanner’s instructions to reset the StabiliTrak system.

How To Turn Off GMC’s StabiliTrak and Traction Control

Follow these simple steps to turn off and disable your GMC’s StabiliTrak and traction control systems:

1. Find the traction control button located on your vehicle’s dashboard.
2. Push the traction control button briefly to deactivate the traction control system. The StabiliTrak system will stay on.
3. Press and hold the same button for approximately 15 seconds to deactivate the StabiliTrak system and traction control.

Press the traction control button to reactivate it and your StabiliTrak system. These systems will turn on again after you turn off and restart your vehicle.
