Diagnostic Procedure

STEP

INSPECTION

ACTION

1
RECORD FREEZE FRAME DATA/SNAPSHOT DATA AND DIAGNOSTIC MONITORING TEST RESULTS TO UTILIZE WITH REPEATABILITY VERIFICATION
Note
•  Recording can be facilitated using the screen capture function of the PC.
•  Record the FREEZE FRAME DATA/snapshot data and DIAGNOSTIC MONITORING TEST RESULTS (fuel system related) on the repair order.
Go to the next step.
2
VERIFY RELATED SERVICE INFORMATION AVAILABILITY
•  Verify related Service Information availability.
•  Is any related Service Information available?
Yes

•  Is there any malfunction?
Yes
Repair or replace the connector and/or terminals, then go to Step 7.
No
Go to the next step.
4
INSPECT PCM CONNECTOR CONDITION
•  Disconnect the PCM connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
•  Is there any malfunction?
Yes
Repair or replace the connector and/or terminals, then go to Step 7.
No
Go to the next step.
5
INSPECT FUEL INJECTOR NO.4 CIRCUIT FOR OPEN CIRCUIT
•  Verify that the fuel injector No.4 and PCM connectors are disconnected.
•  Inspect for continuity between fuel injector No.4 terminal B (wiring harness-side) and PCM terminal 1EF (wiring harness-side).
•  Is there continuity?
Yes
Go to the next step.
No
Refer to the wiring diagram and verify whether or not there is a common connector between fuel injector No.4 terminal B and PCM terminal 1EF.
If there is a common connector:
•  Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for an open circuit.
•  Repair or replace the malfunctioning part.
If there is no common connector:
•  Repair or replace the wiring harness which has an open circuit.
Go to Step 7.
6
INSPECT FUEL INJECTOR NO.4
•  Inspect the fuel injector No.4.
•  Is there any malfunction?
Yes
Replace the fuel injector No.4, then go to the next step.
No
Go to the next step.
7
VERIFY DTC TROUBLESHOOTING COMPLETED
•  Always reconnect all disconnected connectors.
•  Clear the DTC from the PCM memory using the M-MDS.
•  Perform the KOER self test.
•  Is the same DTC present?
Yes
Repeat the inspection from Step 1.
•  If the malfunction recurs, replace the PCM.
Go to the next step.
No
Go to the next step.
8
VERIFY AFTER REPAIR PROCEDURE
•  Perform the “AFTER REPAIR PROCEDURE”.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
No
DTC troubleshooting completed.


Fuel injector (6 pin type)

DTC P0204:00

Fuel injector No.4 circuit operating abnormally

DETECTION CONDITION
•  The injection verification signal is not detected during the fuel injector No.4 operation when the following conditions are met:
―  Battery positive voltage: 8 V or more
Diagnostic support note
•  This is a continuous monitor (CCM).
•  The check engine light illuminates if the PCM detects the above malfunction condition during the first drive cycle.
•  FREEZE FRAME DATA/Snapshot data is available.
•  DTC is stored in the PCM memory.
FAIL-SAFE FUNCTION
•  Limits engine torque.
•  Inhibits the automatic diesel particulate filter regeneration control.
•  Inhibits the manual diesel particulate filter regeneration control.
•  Inhibits the EGR control.
•  Stops the G-vectoring control (GVC).
•  Inhibits engine-stop by i-stop control.
•  Limits the engine transaxle total control.
POSSIBLE CAUSE
•  Fuel injector No.4 connector or terminal malfunction
•  PCM connector or terminal malfunction
•  Open circuit in wiring harness between fuel injector No.4 terminal E and PCM terminal 1EF

Action

1
RECORD VEHICLE STATUS WHEN DTC WAS DETECTED TO UTILIZE WITH REPEATABILITY VERIFICATION
Note
•  Recording can be facilitated using the screen capture function of the PC.
•  Record the freeze frame data/snap shot data.
Go to the next step.
2
INSPECT FUEL INJECTOR NO.4 CONNECTOR CONDITION
