Code P15F5 GMC Description
The Engine Control Module (ECM) is constantly sending the Hybrid/EV Powertrain Control Module 1 serial data messages containing commanded engine crankshaft 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 Diagnostic Trouble Code (DTC) P15F5 when it detects a discrepancy in the structure of this message causing its integrity to be questioned.
An intermittent fault in the CAN circuits will cause DTC P15F5 to set.
What are the Possible Causes of the DTC P15F5 GMC?
- Faulty Starter/Generator Control Module
- Starter/Generator Control Module harness is open or shorted
- Starter/Generator Control Module circuit poor electrical connection
- Faulty Engine Control Module (ECM)
