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