Code P15FC GMC Description
The Hybrid/EV Powertrain Control Module 2 is constantly sending the Hybrid/EV Powertrain Control Module 1 serial data messages containing contactor status data. These serial data messages are sent through circuits which are part of a communication network called the Controller Area Network (CAN).
The Hybrid/EV Powertrain Control Module 1 sets DTC P15FC 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) P15FC to set.
