Lost Comm Powertrain Module

Explicação diagnóstica e técnica
U0100 sets when the gateway or another control module stops receiving any messages from a powertrain-side module or smart sensor -- the ECM/PCM, TCM, or one of the engine-bay LIN-networked sensors (MAP, MAF, EGR, turbo boost, fuel pressure, and similar) that report over a low-speed sub-bus feeding into the high-speed backbone. These nodes live in the engine compartment where connectors see more heat-cycling, vibration, and oil/coolant contamination than any other module class, so a burned or corroded engine-harness connector is the leading cause, followed by a blown fuse for that module's dedicated power circuit.

Estes 199 códigos de diagnóstico compartilham um mesmo mecanismo de detecção e um mesmo caminho de reparo; por isso o MechanicDB os agrupa em uma única família de falhas redigida, em vez de repetir a mesma explicação 199 vezes.
