The 14 V power module, also called the accessory DC power control module, constantly monitors system input and output voltage. This sensor is internal to the 14 V power module and is not serviced separately from the control module.
The vehicle is ON.
Voltage greater than 450 V has been detected.
| • | DTCs P1E40, P1E41 and P1E42 are Type C DTCs. |
| • | The power inverter module requests the hybrid powertrain control module 2 to open the high voltage contactor relays. |
DTCs P1E40, P1E41 and P1E42 are Type C DTCs.
DTCs P1E41 and P1E42 may indicate that the high-voltage contactor relays may have opened while large current flow was present. Conditions such as loss of hybrid powertrain control module 2 power or earth or removal of the high-voltage manual disconnect while the vehicle was driving could create a voltage surge that may set this DTC.
Powertrain Diagnostic Trouble Code (DTC) Type Definitions
If the DTC is set, program the K1 14V power module. If the DTC resets, replace the K1 14 V power module.
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
