ECM Power Source Circuit
CIRCUIT INSPECTION
When the ignition switch is turned on, battery positive voltage is applied to terminal IGSW of the ECM and
the EFI main relay (Marking: EFI) control circuit in the ECM sends a signal to terminal MREL of the ECM
switching on the EFI main relay.
This signal causes current to flow to the coil, closing the contacts of the EFI, main relay and supplying power
to terminals +B of the ECM.
If the ignition switch is turned off, the ECM continues to switch on the EFI main relay for a maximum of 2
seconds for the initial setting of the IAC valve.

Fuel Pump Control Circuit
CIRCUIT DESCRIPTION
In the diagram below, when the engine is cranked, current flows from terminal ST of the ignition switch to
the starter relay coil and also current flows to terminal STA of ECM (STA signal).
When the STA signal and NE signal are input to the ECM, Tr is turned ON, current flows to coil of the circuit
opening relay, the relay switches on, power is supplied to the fuel pump and the fuel pump 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.

(c) Replace the ATF.
(1) Remove the drain plug and drain the fluid.
(2) Reinstall the drain plug securely.
(3) With the engine OFF add new fluid through the oil
filler pipe.
Fluid type: ATF D±II or DEXRON®III (DEXRON®II)
Capacity: 2.5 liters (2.6 US qts, 2.1 Imp. qts)
(4) Start the engine and shift the shift lever into all posi-
tions from P to L position and then shift into P posi-
tion.
(5) With the engine idling, check the fluid level. Add
fluid up to the COOL level on the dipstick.
(6) Check the fluid level is at the normal operating tem-
perature, 70 ± 80 °C (158 ± 176 °F), and add as
necessary.
NOTICE:
Do not overfill.
(d) Check the fluid leaks.
Check for leaks in the transaxle.
If there are leaks, it is necessary to repair or replace O±rings,
gasket, oil seals, plugs or other parts.
(e) Inspect and adjust the throttle cable.
(1) Check that the accelerator pedal is fully released.
(2) Check that the inner cable is not slack.
(3) Measure the distance between the outer cable end
and stopper on the cable.
Standard distance: 0 ± 1 mm (0 ± 0.04 in.)
If the distance is not standard, adjust the cable by the adjusting
nuts.

7. HYDRAULIC TEST
Measure the line pressure.
NOTICE:

Do the test at normal operation fluid temperature 50 ± 80 °C (122 ± 176 °F).

The line pressure test should always be carried out in pairs. One technician should observe
the conditions of wheels or wheel stoppers outside the vehicle while the other is doing the test.

Be careful to prevent SST's hose from interfering with the exhaust pipe.
(1) Warm up the ATF.
(2) Remove the test plug on the transaxle case front left side and connect SST.
(See page AX±17 for the location to connect SST)
SST 09992±00095 (09992±00231, 09992±00271)
(3) Fully apply the parking brake and chock the 4 wheels.
(4) Connect an OBD II scan tool or TOYOTA hand±held tester to DLC3.
(5) Start the engine and check idling speed.
(6) Keep your left foot pressing firmly on the brake pedal and shift into D position.
(7) Measure the line pressure when the engine is idling.
(8) Depress the accelerator pedal all the way down. Quickly read the highest line pressure when
engine speed reaches stall speed.
(9) In the same manner, do the test in R position.
Specified line pressure:
ConditionD position kPa (kgf/cm2, psi)R position kPa (kgf/cm2, psi)

If the measured pressure is not up to the specified value, recheck the throttle cable adjustment and retest.
