STEP 6. Check harness between A-43 (terminal 
No. 2) camshaft position sensor connector and 
C-105 (terminal No. 66) engine-ECU connector.

NOTE: Before checking harness, check intermediate 
connector A-131, and repair if necessary.

• Check output line for short circuit.

Q: Is the check result normal?

YES : 

Go to Step 7 .

NO : 

Repair the damaged harness wire.

STEP 7. M.U.T.-III diagnosis code

• Reconfirmation of diagnosis code.

Q: Is the diagnosis code set?

YES : 

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 ).

NO : 

Intermittent malfunction (Refer to GROUP 
00 

− How to Use Troubleshooting/

Inspection Service Points 

− How to Cope 

with Intermittent Malfunctions ).

STEP 8. Perform voltage measurement at A-43 
camshaft position sensor connector.

• Use special tool harness (MB991709) to connect 

connector, and measure at pick-up harness.

• Ignition switch: ON

• Voltage between terminal No. 3 and earth.

OK: 4.9 

− 5.1 V

Q: Is the check result normal?

YES : 

Go to Step 11 .

NO : 

Go to Step 9 .
