DTC P0650: Malfunction Indicator Light Control Circuit: Description

Powertrain Control Module (PCM) uses Output Driver Modules (ODM) to control many functions of the engine and transaxle. The ODMs supply the ground path for the PCM-controlled device when the PCM commands the device on. Each ODM can control several outputs. Unlike quad driver modules used in earlier model years, the ODMs are able to diagnose each output circuit. The PCM monitors ODMs for circuit conditions that are incorrect for the commanded state of the ODM. If PCM detects an improper circuit condition in the ODM that controls the Malfunction Indicator Light (MIL), DTC P0650 will set.
