• | 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 and each Motor Control Module (MCM) utilize a programmable logic device (PLD) to perform certain input and output functions. The HPCM monitors the ability of the PLD to perform these functions.
• | The control module runs the program to detect an internal fault when the key is ON. |
• | Ignition voltage is 8-18 volts. |
The control module has detected the internal PLD has not turned ON or OFF correctly.
• | DTC P16F9 is a Type A DTC. |
• | The HPCM commands the battery energy control module (BECM) to open the high voltage contactor relays. |
DTC P16F9 is a Type A DTC.
A low 12V battery condition, an intermittent loss of power, or loss of communication to the drive motor generator power inverter module assembly (PIM) may set this DTC.
Powertrain Diagnostic Trouble Code (DTC) Type Definitions
⇒ | If the specified DTCs have set, repair them first. Refer to Diagnostic Trouble Code (DTC) List - Vehicle. |
⇒ | If the specified DTCs have set, repair them first. Refer to Diagnostic Trouble Code (DTC) List - Vehicle. |
⇒ | If the DTC resets, 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.
