Is Your 2015-2016 Suburban Running Rough or Not Starting at All?
If you’re dealing with frustrating engine problems in your Suburban, a faulty Engine Control Module (ECM) is a very likely culprit. As the central computer for your engine, when the ECM starts to fail, it can cause a cascade of issues that seem random and are often difficult to diagnose. I’ve seen hundreds of these GM trucks and SUVs in my shop over the years, and the symptoms of a bad ECM are almost always the same.
Common Symptoms of a Failing ECM
You might be experiencing one or more of these signs. Does any of this sound familiar?
- โ Check Engine Light is on with various communication or sensor codes (like U0100).
- โ The engine cranks but refuses to start.
- โ Unexplained stalling, especially when coming to a stop or at idle.
- โ Rough, inconsistent idling or engine hesitation during acceleration.
- โ A noticeable decrease in fuel economy.
- โ Your scan tool can’t communicate with the ECM.
These problems don’t just go away. They’re caused by the degradation of sensitive electronic components inside the module, often due to years of heat cycles and engine vibration in its location in the front left of the engine bay.
A Real-World Diagnosis
“A customer’s 2016 Suburban 1500 came in last week with these exact symptoms. The owner was frustrated because he’d already replaced a few sensors based on codes, but the intermittent stalling and no-start condition persisted. We hooked up our professional scan tool and found a U0100 ‘Lost Communication with ECM’ code that wouldn’t clear. After verifying the power and ground circuits to the module were good, we knew the ECM itself was the issue. The internal processors were failing, causing it to drop communication with the rest of the vehicle’s network. Replacing the module with a properly programmed unit solved every single one of his issues instantly.”
