STEP 11. Check harness between C-105 (terminal 
No. 1) engine-ECU connector and A-129 (terminal 
No. 2) No. 4 injector connector. 

• Check power supply line for short circuit.

Q: Is the check result normal?

YES : 

Go to Step 12.

NO : 

Repair the damaged harness wire.

STEP 12. M.U.T.-III diagnosis code.

• After erasing the diagnosis code through M.U.T.-

III, start the engine and confirm whether the diag-
nosis code is set.

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 ).

NO : 

Intermittent malfunction (Refer to GROUP 
00 

− How to Use Troubleshooting/

Inspection Service Points 

− How to Cope 

with Intermittent Malfunctions ).

Code No. P2149: Injector Common 2 (cylinder No. 2 and No. 3) Circuit Open <Euro5>

OPERATION

• Refer to Code No. P0202: No. 2 Injector Circuit 

Malfunction 

P.13A-161

. <Euro5>

• Refer to Code No. P0203: No. 3 Injector Circuit 

Malfunction 

P.13A-167

. <Euro5>

FUNCTION

• The engine-ECU monitors peak current from the 

No. 2 and No. 3 injector drive circuits.

TROUBLE JUDGMENT

Check Conditions

• Ignition switch is in "ON" position.

• Except during the engine cranking period

• Battery positive voltage is 8 V or more.

• When an engine-ECU internal capacitor is 

allowed to be charged
