STEP 6. Check harness between A-134 (terminal
No. 1) power steering fluid pressure switch
connector and C-103 (terminal No. 127) engine-
ECU connector.
NOTE: Before checking harness, check intermediate
connectors A-27 and A-115, and repair if necessary.
• Check output line for short circuit.
Q: Is the check result normal?
YES :
Go to Step 7 .
NO :
Repair the harness wire.
STEP 7. M.U.T.-III data list
• Refer to Data List Reference Table
.
a. Item 75: Power steering fluid pressure switch
Q: Is the check result normal?
YES :
Intermittent malfunction (Refer to GROUP
00
− How to Use Troubleshooting/
Inspection Service Points
− How to Cope
with Intermittent Malfunctions ).
NO :
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 ).
STEP 8. Perform voltage measurement at C-103
engine-ECU connector.
• Measure engine-ECU terminal voltage.
• Engine: Idling
• Voltage between terminal No. 127 and earth.
OK:
System voltage (Steering wheel: Stationary)
1 V or less (Steering wheel: Turned)
Q: Is the check result normal?
