Code No. P10DC: Engine/Generator fail



caution
  • If there is any problem in the CAN bus lines, an incorrect diagnosis code may be stored. Prior to this diagnosis, diagnose the CAN bus lines (Refer to GROUP 54C - CAN Bus Diagnostics Table ).
  • Whenever ECU is replaced, ensure that the CAN bus lines are normal.

TROUBLE JUDGEMENT


The PHEV-ECU stores diagnosis code No. P10DC when the engine or the generator fails.

PROBABLE CAUSES



  • Malfunction of the engine
  • Malfunction of the Plug-in Hybrid EV System
  • Malfunction of the GCU
  • The front transaxle fails (peak torque limiter fails)
  • Malfunction of the PHEV-ECU

DIAGNOSIS PROCEDURE


STEP 1. M.U.T.-III diagnosis code.


Check whether the PHEV-ECU stores a diagnosis code which is related to the MPI system or the GCU.

Q. Is the diagnosis code stored?

Diagnose the system according to the stored diagnosis code.
Go to Step 2.

STEP 2. M.U.T.-III other diagnosis code.


Check whether the MPI system related diagnosis code is stored.

Q. Is the diagnosis code stored?

Diagnose the MPI system (Refer to GROUP 13E -Troubleshooting, Diagnsis Chart).
Check whether the MPI system starts and stops the engine properly. (Refer to GROUP 13E - Troubleshooting, Trouble Symptom Chart .) Then go to Step 3.

STEP 3. Check the peak torque limiter.


The engine should run when the generator is driven.

Q. Is the check result normal?

Go to Step 4.
Replace the peak torque limiter. (Refer to GROUP 11H - Balancer Chain Removal and Installation .)

STEP 4. Check whether the diagnosis code is stored again.


Recheck if the diagnosis code is stored.
(1)Erase the diagnosis code.
(2)Turn on the power supply mode of the electric motor switch.
(3)Check if the diagnosis code is stored.

Q. Is the diagnosis code stored?

Replace the PHEV-ECU (Refer to ).
The procedure is complete.
