- Refer to Data List Reference Table
.
- Item 118: No. 2 exhaust gas temperature sensor (catalyst temperature)
- Item 119: No. 3 exhaust gas temperature sensor (DPF temperature)
- Item 120: Exhaust differential pressure sensor
|
|
Q.
Are the check results normal?
|
|
Perform the diagnosis code classified check procedure for the sensor that has shown an abnormal data value (Refer to Inspection Chart for Diagnosis Code ).
|
|
|
|
- Item 208: Short interval DPF regeneration count
|
|
Q.
Is the short interval DPF regeneration counting 10 or more?
|
|
- Initialise the DPF-related parts, and then delete the diagnosis code (Refer to GROUP 00 - Precautions before Service - Initialisation Procedure for Learning Value in Common Rail Engine <4N1>
).
- Item 42: DPF system malfunction service
- Carry out the forcible DPF regeneration (Refer to GROUP 17 - Diesel Particulate Filter (DPF) System - Forcible DPF Regeneration
).
- Carry out the small injection quantity learning procedure (Refer to GROUP 00 - Precautions Before Service - Small Injection Quantity Learning Procedure
).
|
|
Q.
Is diagnosis code P0420 or P1497 set?
|
|
Replace the catalytic converter. When the catalytic converter is replaced, initialise the learning value (Refer to GROUP 00 - Precautions before Service - Initialisation Procedure for Learning Value in Common Rail Engine <4N1>
). On completion, carry out the forcible DPF regeneration (Refer to GROUP 17 - Diesel Particulate Filter (DPF) System - Forcible DPF Regeneration ).
|
|
|
|
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, carry out the forcible DPF regeneration (Refer to GROUP 17 - Diesel Particulate Filter (DPF) System - Forcible DPF Regeneration ).
|
|
|
|
- Initialise the DPF-related parts, and then delete the diagnosis code (Refer to GROUP 00 - Precautions before Service - Initialisation Procedure for Learning Value in Diesel Particulate Filter (DPF) System
).
- Item 42: DPF system malfunction service
- Carry out the forcible DPF regeneration 2 times (Refer to GROUP 17 - Diesel Particulate Filter (DPF) System - Forcible DPF Regeneration
).
note |
Carry out the DPF regeneration 2 times because the assumption of the accumulated amount of the DPF is not stable.
|
- Carry out the small injection quantity learning procedure (Refer to GROUP 00 - Precautions Before Service - Small Injection Quantity Learning Procedure
).
- M.U.T.-III data list
- Item 156: Soot loading by differential pressure
|
|
Q.
Is the check result normal?
|
|
Proceed to troubleshooting for black smoke (Refer to Inspection Procedure 13 ).
|
|
|
|
Replace the DPF. When the DPF is replaced, initialise the learning value (Refer to GROUP 00 - Precautions Before Service - Initialisation Procedure For Learning Value in Diesel Particulate Filter (DPF) System ).
