DIAGNOSIS PROCEDURE


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


Q. Is any other diagnosis code than P2413 set?

Inspection chart for diagnosis codes (Refer to ).
Go to Step 2.

STEP 2. Check EGR valve itself



  • Check EGR valve itself [Refer to GROUP 17 - Emission Control System - Exhaust Gas Recirculation (EGR) System - EGR valve check ].

Q. Is the check result normal?

Go to Step 3.
Replace the EGR valve assembly.

STEP 3. Connector check: C-105 engine-ECU connector



Q. Is the check result normal?

Go to Step 4.

Repair or replace the connector.

STEP 4. Check harness between C-105 (terminal No. 115) engine-ECU connector and A-45 (terminal No. 6) EGR valve assembly connector.





  • Check output line for open/short circuit and damage.

Q. Is the check result normal?

Go to Step 5.

Repair the damaged harness wire.

STEP 5. Check harness between C-105 (terminal No. 130) engine-ECU connector and A-45 (terminal No. 4) EGR valve connector.





  • Check output line for open/short circuit and damage.

Q. Is the check result normal?

Go to Step 6.

Repair the damaged harness wire.

STEP 6. M.U.T.-III diagnosis code.



  • After erasing the diagnosis code through M.U.T.-III, start the engine and confirm whether the diagnosis code is set.

Q. Is the diagnosis code set?

Replace the engine-ECU. When the engine-ECU is replaced, write the chassis number (Refer to GROUP 00 - Precautions Before Service - How to Perform Chassis Number Writing ). After replacing the engine-ECU, register the injector identification code and learn fuel injection (Refer to GROUP 00 - Precautions Before Service - What The Common Rail Engine Learns ). After registering the injector identification code, the vehicle equipped with the DPF carries out the forcible DPF regeneration. (Refer to GROUP 17 - Emission Control - Diesel Particulate Filter (DPF) System - Forcible DPF Regeneration ).
Intermittent malfunction (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunctions ).
