GM “Service StabiliTrak” Causes & Fix

By the Radman Auto Repair team, independent auto repair in Etobicoke since 1999 · Updated November 2026

StabiliTrak is GM’s stability and traction control. When the system sees a fault, or when the engine computer reports a problem such as a misfire, it switches itself off and shows “Service StabiliTrak”, often with the traction light and sometimes reduced power. The message is a symptom; the codes tell you the cause.

Symptoms

What Causes It

Before You Start

• Park on level ground, set the parking brake and chock the wheels. Never work under a car held up only by a jack: use rated jack stands.
• Let the engine and exhaust cool before you touch them; coolant systems are under pressure when hot.
• Wear safety glasses and gloves, and disconnect the 12V battery before unplugging electrical parts or working near airbags.
• Check for open recalls on your VIN (Transport Canada or the manufacturer’s site) before you buy parts: a recall repair is free at the dealer.
• Stability control is off while the message is on: drive carefully, especially on snow and ice.

Step-by-Step: GM Service StabiliTrak

1. Scan all modules. Read codes from the engine computer and the ABS (EBCM) module, not just the engine.
2. Fix engine codes first. If there are misfire or throttle codes, fix those; StabiliTrak often returns on its own.
3. Check the battery. Test the battery and charging voltage; low voltage sets random module faults.
4. Check wheel speed sensors. Compare all four wheel speeds in live data while driving slowly; a sensor reading zero or erratic is the fault.
5. Inspect the sensor and wire. Look for a broken wire, corroded connector or rust lifting the sensor at that wheel.
6. Check the steering angle. With the wheels straight, the steering angle in live data should be close to zero.
7. Check the brake switch. Confirm the brake lights and the brake switch reading change when you press the pedal.
8. Repair and calibrate. Replace the faulty part, clear the codes and calibrate the steering angle sensor if your scan tool calls for it.

When to Stop and Bring It In

• There are ABS module or internal codes.
• The message comes with brake warning lights or a hard pedal.
• You can’t read ABS codes with your scan tool.
• Steering angle calibration isn’t possible with your tool.

Alex is a great guy. He took the time to respond by phone and walk me through my options for my Tesla Model Y 2024 and gave me his perspectives as a Tesla owner. Top recommendation in my books for the Toronto area.

I cannot say enough good things about Livio and the team at Radman Auto Repair in Rexdale. We brought in my son’s 2015 Mitsubishi Lancer because the A/C was malfunctioning. We had already been to two other shops, paid for diagnostics, and received different explanations, so we were frustrated and unsure what to do next. Livio was outstanding. He listened carefully, looked at the issue, and explained everything clearly and in detail in a way that actually made sense. He was able to narrow down what was going on within minutes, without guessing, pressure, or recommending unnecessary work. What really stood out was that he did not charge us another diagnostic fee after learning we had already paid for two separate diagnoses. Even better, the work was completed the same day, which was a huge relief. It is rare to find a mechanic who is knowledgeable, honest, patient, efficient, and genuinely focused on helping customers understand the real issue before they spend money on repairs. Livio truly gets it. We are so happy we found Radman Auto Repair and would highly recommend Livio and his team to anyone looking for trustworthy, skilled, and customer-focused service..

My 2015 Honda CR-V was blowing hot air and making noise when the A/C was on. The Compressor and Expansion valve needed replacement due to metal debris in the system. I rarely write reviews, but I felt it would be wrong not to appreciate Radman for their service, especially after what I went through before finding them. I’m writing this one month after the repair because I wanted to test my A/C on multiple long trips before recommending them. One thing I learned from this experience is that many mechanics know how to replace parts, but very *few follow the right procedures* and perform the proper checks. I initially went for a cheaper repair at a local mechanic. The problem came back, and afterward he didn’t seem to know what to do next. I found Radman through Google reviews without any personal recommendation, so I was taking a chance. They properly diagnosed the issue, explained everything clearly before starting the work, didn’t exaggerate the problem, and charged me a reasonable price. A/C issues can be complicated but they answered all my questions and I honestly haven’t had such a good and detailed conversation with a mechanic in the GTA about an A/C problem. Their knowledge and experience with A/C systems really stood out. I also had a catalytic converter issue. Another mechanic simply recommended replacing it, which would have cost at least $2,000. Radman explained that considering the age and condition of my 2015 CR-V, such an expensive replacement might not make sense. They gave me the replacement cost but also suggested trying Cataclean first. I tried it, and so far I haven’t had any issues. After a month and several long trips, my A/C is still working well. It’s rare to find this combination of knowledge, transparency, and honesty. Thank you, Radman, for the knowledgeable and honest service. I genuinely appreciate it.

I fix my cars myself but I always go to Radman for AC work. Been coming here for years and they do great work and are fairly priced. The guys are honest and reliable. Very clean waiting room too!

Finding a mechanic who actually understands EVs and is completely trustworthy is hard to come by, but ⁠Radman Repair is excellent. The service was top-notch, they explained everything to me with so much patience, and the overall experience was a 10/10. 100% recommended!
