The p0650 is an output driver fault within the pcm, an output driver is an internal ground inside the pcm. Before you replace the pcm check the MIL fuse first, it could be blown. If it isnt then you would be looking at a possible pcm problem, her is how it works, Output driver modules (ODMs) are used by the powertrain control module (PCM) to turn ON many of the current-driven devices that are needed to control various engine and transaxle functions. Each ODM is capable of controlling up to 7 separate outputs by applying ground to the device which the PCM is commanding ON. Unlike the quad driver modules (QDMs) used in prior model years, ODMs have the capability of diagnosing each output circuit individually. DTC P0650 set indicates an improper voltage level on the output circuit that controls the malfunction indicator lamp (MIL).
Post back with what you find.
