- MDP learning value is decreased due to aged in-
jector #1.
- MDP learning value is decreased due to aged in-
jector #2.
- MDP learning value is decreased due to aged in-
jector #3.
- MDP learning value is decreased due to aged in-
jector #4.
- MDP learning value is decreased due to aged in-
jector #5.
- Causes (Idle range MDP learning)
• The MDP is not learned again until driving over
50,000 km after the MDP is learned.
- Conditions for MDP learning (Idle)
• Leaning twice for each cylinder (attempt ev-
ery 5 sec.)
• Initial MDP learning: coolant temperature > 60°C
• Fuel temperature: 0 ~ 80°C
• Vehicle speed: Idle.
• The tachometer’s needle vibrates while learn-
ing idle MDP.
• Replace ECU after learning.
- Causes
• It occurs twice for each cylilnder if MDP is not
learned again until driving over 50,000 km af-
ter the MDP is learned.
- Actions
• Check knock sensor and wiring.
• Check injector specification.
• Check C3I/C2I.
- C3I
• There is no C3I data in ECU or the checksum is
faulty.
- C3I
• The error is occurred while sending C3I data
in ECU to RAM.

3. REMOVAL AND INSTALLATION OF INJECTOR
Return hose
Connector
• Plug the hole with protective cap.
• Do not spill the oil when disconnecting
the hose.
2. Unscrew the mounting nuts (17 mm) on the high pressure line and disconnect the fuel pipes. Before disconnecting
it, remove the foreign material around the injector and the fuel pipe with an air gun.
Fuel Pipe
When installing, position
the number on the pipe to
face the common rail.

180° ± 20°
4. Remove the injector using a special tool.
5. Install in the reverse order of removal. However, do not remove the protective cap from new injector before installing.
6. Perform the C3I coding for D27DTP engine or C2I coding for D27DT engine.
* When installing the
holder, replace the
holder mounting
bolts with new ones.
• Plug the injector with a protective cap.
NOTICE
• If the washer is not removed
together with the injector, re-
move the washer from the
engine using the special tool
shown in the figure.

C3I (20 digits)
* Coding of D27DT Engine Injector: C2I (16 digits:
samp with current version)

D27DTP Engine: C3I Coding
C2I Label
• If the injector/ECU has been replaced or the injec-
tor system failure is suspected, go to C2I or C3I
Coding item and check the injector and coded in-
jector C2I or C3I value.
NOTICE
• The C2I value of injector is on
the label.
• C2I coding number: 16 digits
(ex, C0 2D 835. )
• C3I coding number: 20 digits
(ex, ZD87E03R. )
