3-2. If you enter the invalid C2I or C3I value of the rel-
evant injector, the message as shown in figure ap-
pears with alarm sound.
3-1. If you press [ENTER] on C3I (C2I) display, the recoding menu of C3I or C2I appears.
C3I is coded by using alphabet letters up to Z. If you want to change a number in the coding letters, press the
number keypad of SCAN-100. If you press PgUp or PgDn key, you can enter alphabet letters again.
3-3. If you enter the valid C2I or C3I value of the relevant
injector, the message as shown in figure appears
with alarm sound.
• If you want to return to previous screen, press
key. You can see the previous C2I or C3I value.
NOTE
• If you return to previous screen, press
key.
Then, the new C2I or C3I values are displayed.
NOTE
• The alphanumeric letters are from A ~ Z followed by 0 ~ 9.
NOTE
• When coding C2I or C3I, if you select the engine
out of the models, the injector coding items per-
taining to the engine appear.

D27DTP/D27DT (EU4)
1. COMPONENTS AND OVERVIEW
The diameter of fuel supply pipe between HP pump and the common rail and the diameter of fuel pipe between the
common rail and the injector have been increased to provide the increased volume of fuel injection for the higher
output of D27DTP (POWER UP) engine.
Also, the orifice has been added to prevent the fuel pulsation in the common rail and the HP pump fuel supply line.
To control the amount of injected fuel to each cylinder precisely and evenly, it is important to prevent the fuel
pulsation occurred during the fuel supply and fuel cut.
The followings are the fuel pipes for the D27DT engine and D27DTP (POWER UP) engine:

- Check the IMV wiring harnesses.
- Check the ECU wiring harnesses.
• Check ECU’s pin A76 for open and short.
- Check the Rail pressure sensor.
• Supply voltage: 5 ± 0.1V
• Output voltage at 1600 bar: 4.055 ± 0.125V
• Output voltage at atmospheric pressure: 0.5 ±
0.04V
- Check low-pressure fuel system.
• Check fuel in fuel reservoir and air penetration.
• Check fuel filter’s specification.
- Check high-pressure fuel system.
• Check fuel rail and high-pressure pipe for leaks.
- Check IMV’s resistance (5.44
Ω).
• If the resistance is out of specification, replace
the high-pressure pump and IMV.

Ú Preceding Work: Remove the engine cover.
1. Unscrew the mounting nuts and disconnect the fuel
supply pipes.
2. Disconnect the fuel pressure sensor connector and
remove the clamps.
Tightening torque
40 ± 1.0 Nm
3. Remove the high pressure fuel pipe and unscrew the common rail mounting bolts (3EA - hexagon: 6 mm) and
remove the common rail.
• When installing, replace the fuel supply pipes with
new ones.
• Plug the fuel hole to the common rail with a pro-
tective cap.
