About this episode

A 2015 Chevrolet Traverse with a no-crank issue leads to a deep dive into multiple electrical failures, likely caused by a lightning strike. The diagnostic journey uncovers no communication with the ECM, a faulty fuse box, a shorted fuel pump control module, and a BCM with internal shorts causing turn signals to stay on. The episode highlights detailed testing methods, GM network architecture, and the complexities of diagnosing intertwined module failures. The host shares insights on interpreting test results and the unusual challenges posed by this vehicle's condition.
