P0EED concerns the active discharge path on the high-voltage side, the circuit that drains the DC link capacitors once the contactors have opened so that no dangerous voltage lingers. The code says this path does not perform as intended, whereas P0C76 only judges how long the voltage takes to fall. FCA lists P0EED-00 for the 2017 Chrysler Pacifica Hybrid in bulletin 08-107-17, next to P0C76, P0C77 and P0AFA: a loose terminal bolt where the high-voltage lead joins the inverter module (PIM) could arc, the MIL came on and propulsion might be lost. Repair was a torque check to 25 N·m, or a new inverter module and cable if arcing marks were found. As a reference for the timing side, GM's P0C76 fails when the inverter still reads above 200 V 3.5 s after opening, Type A.

Likely causes

Loose or arcing high-voltage cable terminal at the inverter module (FCA 08-107-17)
Discharge resistor or its switching transistor open or degraded
Internal fault in the inverter or its voltage measurement
Main contactor sticking closed so the bus stays charged

Symptoms

  • MIL or hybrid system warning on
  • Loss of propulsion or vehicle will not enter ready mode
  • Further high-voltage codes such as P0C76 or P0C77 stored at the same time
