DIAGNOSTICS ECD SYSTEM (1CD−FTV)(From September, 2003)
AVENSIS Supplement (RM1045E)
DTC P0200 INJECTOR CIRCUIT / OPEN
HINT:
S For more information on the EDU, see page 05 −255.
S If P0200 is present, refer to the diagnostic trouble codes (DTCs) table for the fuel system on page
05 −255.
CIRCUIT DESCRIPTION
The EDU has been adopted to drive the injector at high speeds. The EDU has realized the high −speed driv-
ing under high −pressurized fuel conditions using the DC/DC converter that provides a high −voltage, and the
quick −charging system.
Soon after the EDU receives an injection command (IJT) signal from the ECM, the EDU responds to the com-
mand with injector injection confirmation (IJF) signal when the current is applied to the injector.

INSPECTION PROCEDURE
HINT:
SIf different DTCs related to different systems that have terminal E2 as the ground terminal are output
simultaneously, terminal E2 may have an open circuit.
SRead freeze frame data using the hand−held tester. Freeze frame data records the engine conditions
when a malfunction is detected. When troubleshooting, freeze frame data can help determine if the
vehicle was running or stopped, 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.
1CHECK HARNESS AND CONNECTOR(INTAKE SHUTTER (THROTTLE VALVE)

(a) Disconnect the I18 intake shutter position sensor connec-
tor.
(b) Disconnect the E12 and E13 ECM connectors.
(c) Measure the resistance between the terminals of the E12
and E13 ECM connectors.
