DESCRIPTION
The D-4S system has two fuel injection systems. One is an in-cylinder direct injection system that directly injects pressurized fuel into the combustion chamber. The other is an intake port injection system. The ECM determines which fuel injection system to use in accordance with the engine conditions. The direct injection system uses an injector driver (EDU) built into the ECM to rapidly operate the direct fuel injector assemblies. It converts injection request signals from the ECM to high-voltage and high-current injector-drive signals that drive the direct fuel injector assemblies.

MONITOR DESCRIPTION
The fuel injection sequence occurs in numerical order from No. 1 to No. 4.
The ECM monitors the Injector Driver (EDU) at all times. If drivers or direct fuel injector assembly is malfunctioning, the EDU sends direct fuel injector assembly operation condition signals (fail signals) to the ECM. When the ECM receives the signals, the ECM stops the fuel injection control of the appropriate cylinders, cuts voltage to the appropriate D INJ relay, and illuminates the MIL.

CONFIRMATION DRIVING PATTERN
-
Connect the GTS to the DLC3.
-
Turn the ignition switch to ON.
-
Turn the GTS on.
-
Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
-
Turn the ignition switch off and wait for at least 30 seconds.
-
Start the engine.
-
Idle the engine for 15 seconds or more [A].
-
Turn the GTS on.
-
Enter the following menus: Powertrain / Engine / Trouble Codes [B].
-
Read the pending DTCs.
Tech Tips
-
If a pending DTC is output, the system is malfunctioning.
-
If a pending DTC is not output, perform the following procedure.
-
-
Enter the following menus: Powertrain / Engine / Utility / All Readiness.
-
Input the DTC: P020113, P020213, P020313, P020413 or P062D13.
-
Check the DTC judgment result.
GTS Display Description NORMAL
-
DTC judgment completed
-
System normal
ABNORMAL
-
DTC judgment completed
-
System abnormal
INCOMPLETE
-
DTC judgment not completed
-
Perform driving pattern after confirming DTC enabling conditions
Tech Tips
-
If the judgment result is NORMAL, the system is normal.
-
If the judgment result is ABNORMAL, the system has a malfunction.
-
If the judgment result is INCOMPLETE, perform steps [A] through [B] again.
-
WIRING DIAGRAM
CAUTION / NOTICE / HINT
Note
Inspect the fuses for circuits related to this system before performing the following procedure.
Tech Tips
-
If the current from the D INJ relay is cut because DTC P062D13 is stored, DTC P123513 will be stored even if the fuel pump assembly (for high pressure side) is normal.
-
Read Freeze Frame Data using the GTS. The ECM records vehicle and driving condition information as Freeze Frame Data the moment a DTC is stored. When troubleshooting, Freeze Frame Data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
PROCEDURE
-
CHECK DTC OUTPUT (DTC P020113, P020213, P020313, P020413 AND/OR P062D13)
-
Connect the GTS to the DLC3.
-
Turn the ignition switch to ON.
-
Turn the GTS on.
-
Enter the following menus: Powertrain / Engine / Trouble Codes.
-
Read the DTCs.
Powertrain > Engine > Trouble CodesResult Result Proceed to DTC P020113, P020213, P020313 or P020413 is output A 3 or more of the following DTCs are output: P062D13, P020113, P020213, P020313 and P020413 B P062D13 is output
