Code P15F2 2014 Chevrolet Silverado Description

This diagnostic applies to internal microprocessor integrity conditions within the Engine Control Module (ECM). The hybrid powertrain control module is internal to the power inverter module, often referred to as the drive motor generator power inverter module and is not serviced separately. The hybrid powertrain control module sends an engine torque requested message to the ECM over the serial data circuits. The ECM monitors the data to verify the indicated engine torque requested calculation is correct. The ECM processor monitors the data to verify that the engine torque command is correct. The Diagnostic Trouble Code (DTC) will be set when the control module has detected an internal malfunction.
