C3I Data

- 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.

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.

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....)
