This is an internal fault detection of the drive motor generator power inverter module (PIM) assembly. This fault is handled inside the PIM and no external circuits are involved.
The inverter self test is complete.
The control module does not detect voltage at the isolated gate bi-polar transistor (IGBT) bias supply.
• | DTCs P0C0B and P0C0E are Type A DTCs. |
• | The PIM commands the battery energy control module (BECM) to open the high voltage contactor relays. |
DTCs P0C0B and P0C0E are Type A DTCs.
Powertrain Diagnostic Trouble Code (DTC) Type Definitions
Ignition ON, retest for DTC P0C0B or P0C0E.
⇒ | 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.
