How to Reset Service Stabilitrak Light GMC Sierra [5 steps]

Did you suddenly see the StabiliTrak warning light in the driver information display while driving?

It means your GMC Sierra’s wheel may slip, and it could become a safety issue while driving.

Most GM cars have StabiliTrak sensors to warn drivers when a wheel is slipping.

When you see the StabiliTrak warning light on your dashboard, you should diagnose the actual cause before resetting the warning light.

The StabiliTrak warning light can also be reset directly, but this is not a permanent fix.

In this article, I have explained the StabiliTrak warning light’s meaning, causes, and resetting steps.

What is StabiliTrak?

StabiliTrak is a safety feature known as an “Electronic Stability Control System.”

It is designed to balance vehicle stability and prevent slides or skids.

Most GM vehicles use this feature, including the GMC Sierra.

StabiliTrak uses different sensors to monitor vehicle speed, wheel slippage, and steering angle.

When the StabiliTrak system notices unusual responses, it changes the engine’s torque, slows down the vehicle, or applies the brakes to stabilize the truck.

The system is helpful when snowy or rainy, especially if the road is wet or slippery.

The StabiliTrak system is put in to keep a car safe and easy to drive by keeping it from sliding or skidding.

Symptoms of Bad Service StabiliTrak

If there are any issues with the StabiliTrak system, you will experience the following six common symptoms:

  1. StabiliTrak warning light
  2. Hard Shifting
  3. Rough idling
  4. Unresponsive braking
  5. Changes in handling
  6. Trouble codes such as C05621, P0121, P0011, P0300, etc.

When you see any of these six symptoms, you should check the car to see what is wrong with the StabiliTrak.

What Causes StabiliTrak Light to Come On [6 Causes]

Several factors may cause the StabiliTrak light to come on.

But the most common causes that are directly responsible for the StabiliTrak warning light coming on are listed below:

1. Faulty Wheel Speed Sensor

The StabiliTrak system functions based on signals coming from sensors.

The wheel speed sensor is one of those sensors.

StabiliTrak triggers the warning light if the faulty sensor sends incorrect data.

2. Faulty Alternator

The alternator is a crucial part of supplying electricity during engine operation.

A faulty alternator causes various problems, including the StabiliTrak warning light.

3. Faulty Brake System

The StabiliTrak system is directly related to brake systems, like ABS modules or brake pressure sensors.

The ABS module and the brake pressure sensors are essential for a properly functioning StabiliTrak system.

The warning light may show up if there are problems with the ABS or the brake pressure sensor.

4. Faulty Steering Angle Sensor

The steering angle sensor is one of many sensors that StabiliTrak relies on.

If there is a problem with the steering angle sensor, the StabiliTrak warning light can come on.

5. Electrical Issue

Many electrical wires connect the StabiliTrak system and sensors.

The sensors and StabiliTrak may both be working, but there may be a problem with the electrical connections.

That’s why the warning light may appear on the vehicle’s dashboard.

6. Issues with the StabiliTrak Module

The StabiliTrak warning light may also come on due to problems with the StabiliTrak module itself.

Therefore, when the warning light illuminates, you should also check the StabiliTrak system.
