HINT:
For more information on the EDU, see page 05±517.
If P0200 are present, Use the diagnostic trouble code matrix for fuel sy\
stem, see page 05±517.
CIRCUIT DESCRIPTION
The EDU has been adopted to drive the injector at high speeds. The EDU has \
realized high±speed driving
under high fuel pressure conditions using the DC/DC converter that provides a\
high±voltage, quick±charging
system.
Soon after the EDU receives an injection command signal (IJT) from the\
ECM, the EDU responds to the com-
mand with injector injection confirmation signal (IJF) when the current is\
applied to the injector.

DIAGNOSTIC TROUBLE CODE CHART
HINT:
Using SST 09843±18040, connect the terminal Tc and CG of the DLC3.
If malfunction is not found when inspecting parts, inspect the ECU and grou\
nd points for poor contact.
If a malfunction code is displayed during the DTC check, check the circuit\
listed for that code. For de-
tails of each code, refer to the ºSee pageº for respective ºDTC No.º\
in the DTC chart.
When 2 or more DTCs are detected, perform circuit inspection one by one unti\
l the problem is identi-
fied.
