• | Perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure. |
• | Review Strategy Based Diagnosis for an overview of the diagnostic approach. |
• | Diagnostic Procedure Instructions provides an overview of each diagnostic category. |
This diagnostic applies to internal microprocessor integrity conditions within the hybrid powertrain control module (HPCM). The HPCM monitors its ability to read and write to the memory. The HPCM processor monitors the data to verify that the indicated engine torque delivered calculation is correct.
• | The control module runs the program to detect an internal fault when the key is ON for 5 seconds. |
• | Ignition voltage is 8-18 volts. |
The control module has detected an internal malfunction.
• | DTC P15F0 is a Type A DTC. |
• | The HPCM commands the battery energy control module (BECM) to open the high voltage contactor relays. |
DTC P15F0 is a Type A DTC.
Powertrain Diagnostic Trouble Code (DTC) Type Definitions
Program the PIM with the latest software version and recheck for DTCs.
⇒ | If the DTC resets after programming or if the PIM already contains the latest software version, replace the PIM. |
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
