Restore Peak Performance to Your GM Truck or SUV
Is your 2015-2016 Chevrolet Suburban, Tahoe, or other compatible GM vehicle suffering from perplexing engine issues? Unexplained check engine lights, rough idling, stalling, or a sudden drop in fuel economy are common indicators of a failing Engine Control Module (ECM). The ECM is the brain of your vehicle’s engine, managing everything from fuel injection and ignition timing to emissions controls. When it falters, the entire system is compromised. This genuine GM Engine Control Module, part number 12669318, is the definitive solution to restore your vehicle’s factory performance and reliability.
Common Symptoms of a Failing ECM
- ✔ Persistent Check Engine Light (CEL) with communication-related trouble codes (e.g., U-codes).
- ✔ Engine stalling or shutting off unexpectedly while driving.
- ✔ Rough or erratic idling and hesitation during acceleration.
- ✔ Noticeable decrease in fuel efficiency.
- ✔ Misfire codes that don’t resolve after replacing plugs, coils, or injectors.
- ✔ Complete no-start condition where the engine cranks but won’t fire.
- ✔ Intermittent issues with other electronic systems controlled by the ECM.
From the Diagnostic Bay
We had a 2015 Escalade come into the shop with a ghost of a problem. The owner complained of random stalling at red lights and a check engine light that would come and go. We checked for vacuum leaks, tested fuel pressure, and scanned for codes, which showed intermittent communication loss with the ECM. After confirming all wiring and grounds were solid, we knew the internal logic of the original module was failing. We installed a new, VIN-programmed ECM, performed the security relearn, and the truck ran perfectly. The customer was thrilled to have his reliable vehicle back without the dealership hassle and expense. This highlights the importance of addressing the root cause, which is often the ECM itself.
