YES :
Go to Step 12 .
NO :
Proceed to the inspection procedure by
diagnosis code for the abnormal waveform
(Refer to Inspection Chart for Diagnosis
Code
).
STEP 12. M.U.T.-III actuator test.
• Refer to Actuator Test Reference Table
a. Item 19: Suction control valve
Q: Is the check result normal?
YES :
Go to Step 13 .
NO :
Replace the suction control valve. After
replacing the suction control valve, learn the
supply pump (Refer to GROUP 00
−
Precautions Before Service
− What The
Common Rail Engine Learns ).
STEP 13. Check suction control valve itself.
• Check suction control value itself (Refer to
).
Q: Is the check result normal?
YES :
Go to Step 14 .
NO :
Replace the suction control valve. After
replacing the suction control valve, learn the
supply pump (Refer to GROUP 00
−
Precautions Before Service
− What The
Common Rail Engine Learns ).
STEP 14. M.U.T.-III data list.
• Refer to Data List Reference Table
.
a. Item 63: Rail pressure sensor
b. Item 64: Rail pressure target
Q: Are the check results normal?
YES :
Go to Step 16 .
NO :
Go to Step 15 .
STEP 15. Replace the rail pressure sensor.
• Replace the common-rail assembly.
Q: Does trouble symptom persist?
YES :
Go to Step 18 .
NO :
The procedure is complete.
STEP 16. Check compression pressure.
• Check compression pressure (Refer to GROUP
11A
− On-vehicle Service − Compression Pres-
sure Check ).
Q: Is the check result normal?
YES :
Go to Step 17 .
NO :
Check and repair the engine itself.
STEP 17. Check injector itself.
• Check injector itself (Refer to
).
Q: Is the check result normal?
YES :
Go to Step 18 .
NO :
Replace the injector at the failed cylinder.
After replacing the Injector, register the
injector identification code and learn fuel
injection (Refer to GROUP 00
− Precautions
Before Service
− What The Common Rail
Engine Learns ).
STEP 18. Check the trouble symptoms.
Q: Does trouble symptom persist?
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 Malfunction ).
