The hybrid powertrain control module (HPCM) uses ignition 1 circuit terminal voltage to monitor the 12V system voltage. Ignition 1 circuit voltage also powers several of the internal drive motor generator power inverter control module (PIM) components.
Ignition is ON.
The control module has detected ignition 1 circuit voltage is 2V or less.
• | DTC P2534 is a Type A DTC. |
• | The HPCM commands the engine OFF. |
DTC P2534 is a Type A DTC.
Powertrain Diagnostic Trouble Code (DTC) Type Definitions
⇒ | If not within the specified range, test the signal circuit for a short to ground or open/high resistance. If the circuit tests normal, replace the PIM. |
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
