DESCRIPTION

The D-4S system has two fuel injection methods. One is the in-cylinder direct injection method that directly injects pressurized fuel into the combustion chamber. The other is the intake port injection method. The ECM determines which fuel injection method to use in accordance with the engine conditions. For the in-cylinder direction injection method, the 2 injector drivers in the engine compartment operate the fuel injectors (for direct injection) at high speeds.

Each injector driver receives fuel injection request signals from the ECM and converts the signals to high voltage / high current injector operation signals to operate the fuel injectors (for direct injection). The fuel injection sequence occurs in the following order: No. 1, No. 8, No. 7, No. 3, No. 6, No. 5, No. 4, No. 2. The ECM monitors each injector driver at all times. If drivers or injectors are malfunctioning, the injector driver sends fuel injector operation condition fail signals (INJ1 to INJ4) to the ECM.

MONITOR DESCRIPTION

The injector driver sends the injection confirmation signal (INJ) to the engine control module (ECM). Using this signal, the ECM monitors the direct fuel injector operation. If the ECM receives no INJ signal in 20 consecutive engine rotations, the ECM illuminates the MIL and sets the DTC immediately. Then, the ECM aborts the direct fuel injection of the appropriate cylinder, or turns off the EDU relay to shut the injector driver power source.

MONITOR STRATEGY

Required Sensors/Components	Injector for direct injection, No. 1 injector driver (EDU), No. 2 injector driver (EDU)
Frequency of Operation	Continuous

CONFIRMATION DRIVING PATTERN

Connect the GTS to the DLC3.
Turn the engine switch on (IG) and turn the GTS on.
Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
Turn the engine switch off and wait for at least 30 seconds.
Turn the engine switch on (IG) and turn the GTS on.
Start the engine.
Idle the engine for 15 seconds or more [A].
Enter the following menus: Powertrain / Engine / Trouble Codes / Pending.
Read pending DTCs [B].
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: P0201, P0202, P0203, P0204, P0205, P0206, P0207, P0208, P062D or P062E.

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
N/A	Unable to perform DTC judgment Number of DTCs which do not fulfill DTC preconditions has reached ECU memory limit

Tech Tips

If the judgment result shows NORMAL, the system is normal.
If the judgment result shows ABNORMAL, the system has a malfunction.
If the judgment result shows INCOMPLETE or N/A, perform steps [A] and [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 INJ NO. 1 relay is cut because DTC P062D is stored, DTC P1235 will be stored even if the fuel pump (for high pressure side) is normal.
If the current from the INJ NO. 2 relay is cut because DTC P062E is stored, DTC P1236 will be stored even if the fuel pump (for high pressure side) is normal.
Bank 1 refers to the bank that includes the No. 1 cylinder*.

*: The No. 1 cylinder is the cylinder which is farthest from the transmission.
Bank 2 refers to the bank that does not include the No. 1 cylinder.
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

Connect the GTS to the DLC3
Turn the engine switch on (IG).
Turn the GTS on.
