FUEL PUMP CONTROL CIRCUIT
CIRCUIT DESCRIPTION
In the diagram below, when the engine is cranked, current flows from terminal ST of the igni\
tion switch to
the starter relay coil and also current flows to terminal STA of the ECM (STA signal).
When the STA signal and NE signal are input to the ECM, Tr is turned ON, current flows to the coil of the
circuit opening relay, the relay switches on, power is supplied to the fuel pump and the fuel p\
ump operates.
While the NE signal is generated (engine running), the ECM keeps Tr ON (circuit opening relay ON) and the
fuel pump also keeps operating.

INSPECTION PROCEDURE
1PERFORM ACTIVE TEST USING HAND±HELD TESTER(OPERATION OF CIRCUIT
OPENING RELAY)
(a)Turn the ignition switch ON.
(b)Select the item ºDIAGNOSIS / OBD/MOBD / ACTIVE TEST / FUEL PUMP / SPD\
º.
(c)Perform the active test with the engine stopped.
Result: The circuit opening relay operates.

AVENSIS REPAIR MANUAL (RM1018E)
ECM POWER SOURCE CIRCUIT
CIRCUIT DESCRIPTION
When the ignition switch is turned ON, battery positive voltage is applied to terminal IGSW of the ECM and
the EFI relay (Marking: EFI) control circuit in the ECM sends a signal to terminal MREL of the ECM switching
on the EFI relay.
This signal causes current to flow to the coil, closing the contacts of the EFI relay and supplying power to
terminal +B of the ECM.
If the ignition switch is turned off, the ECM continues to switch on the EFI relay for a maximum of 2 seconds
for the initial setting of the throttle valve.
