Real-World Repair Story
Real-World Repair Story
A customer brought in an ’11 Buick Enclave (which uses the same platform and ECM as the Acadia) with an intermittent stalling problem that no one could solve. It threw no consistent codes, just an occasional U0100 for lost communication. After checking all the usual suspects—wiring, grounds, fuel pressure—we focused on the ECM. On the bench, we found that heat soak was causing an internal processor to fail. We installed a pre-programmed 2010-2011 Acadia ECM like this one, and the problem was solved instantly. These intermittent issues are where a quality, tested module makes all the difference.
