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 fuel injector assemblies
(for direct injection). It converts injection request signals from the
ECM to high-voltage and high-current injector-drive signals that drive
the fuel injector assemblies (for direct injection). |

The fuel injection sequence occurs in numerical order from No. 1 to No. 6.
The
ECM monitors the Injector Driver (EDU) at all times. If drivers or fuel
injector assembly (for direct injection) are malfunctioning, the EDU
sends fuel injector assembly (for direct injection) 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. MONITOR STRATEGY |

 CAUTION / NOTICE / HINT
NOTICE: Inspect the fuses for circuits related to this system before performing the following procedure.
HINT:
- 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 Techstream. 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.
