STEP 12. Check harness between A-152 (terminal
No. 4) battery current sensor connector and C-
103 (terminal No. 138) engine-ECU connector.
• Check output line for open/short circuit and dam-
age.
Q: Is the check result normal?
YES :
Go to Step 6 .
NO :
Repair the damaged harness wire.
Code No. P1625: Injection Quantity Compensation Value Error
FUNCTION
• Correction data of the injector built in the engine
is written to the engine-ECU.
• The engine-ECU checks whether the correction
data thus written is valid.
TROUBLE JUDGMENT
Check Condition
• Ignition switch is in "ON" position.
Judgment Criterion
• An error is detected during three-side majority
decision check or upper/lower limit check of an
injector correction value.

PROBABLE CAUSE
• Failed engine-ECU
DIAGNOSIS PROCEDURE
STEP 1. Injector identification code data check
• Check whether injector identification code data is
correctly written to the engine-ECU in M.U.T.-III.
Q: Is the check result normal?
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 :
Go to Step 2 .
STEP 2. Rewrite the injector identification code
data again.
• Rewrite the injector identification code data
(Refer to GROUP 00
− Precautions Before Serv-
ice
− Injector Identification Code Registration
Procedure ).
• After rewriting the injector identification code data
again, recheck for abnormal 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 :
The check is end.
Code No. P1626: Injection Quantity Compensation Value Not Coding
FUNCTION
• The engine-ECU checks whether injector correc-
tion data is written to the engine-ECU.
TROUBLE JUDGMENT
Check Condition
• Ignition switch is in "ON" position.
Judgment Criterion
• No record of writing injector correction data
PROBABLE CAUSE
• Failed engine-ECU
DIAGNOSIS PROCEDURE
STEP 1. Write the injector identification code
data.
• Write the injector identification code data (Refer
to GROUP 00
− Precautions Before Service −
Injector Identification Code Registration Proce-
dure ).
• After writing the injector identification code data,
recheck for abnormal 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

register the injector identification code and
