To improve vehicle shift feel, the Transmission Control Module (TCM) is constantly sending the Engine Control Module (ECM) serial data messages with information regarding its request for modifying engine speed or torque. The ECM sets this code when it detects a discrepancy in the structure of this message causing its integrity to be questioned. An intermittent fault in the Controller Area Network (CAN) circuits will cause Diagnostic Trouble Code (DTC) P150C to set.
