(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: 3.9 liters (4.1 US qts, 3.4 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 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 the standard, adjust the cable by the ad-
justing nuts.

O/D Cancel Signal Circuit
CIRCUIT DESCRIPTION
While driving uphill with cruise control activated, in order to minimize gear shifting and provide smooth cruis-
ing overdrive may be prohibited temporarily under some condition.
The cruise control ECU sends O/D cut signals to the ECM as necessary and the ECM cancels overdrive
shifting until these signals are discontinued.

(c) Using TOYOTA hand±held tester, check the DTC.
(1) Hook up the TOYOTA hand±held tester to the
DLC2.
(2) Read the DTC by following the prompts on the tes-
ter screen.
Please refer to the TOYOTA hand±held tester oper-
ator 's manual for further details.
(d) Clear the DTC.
(1) Using SST, connect terminals Tc and E
1 of DLC2 or
DLC1 and remove the short pin from DLC1.
SST 09843 ± 18020
(2) Turn the ignition switch ON.
(3) Clear the DTC stored in ECU by depressing the
brake pedal 8 or more times within 5 seconds.
(4) Check that the warning light shows the normal
code.
(5) Remove the SST from the terminals of DLC2 or
DLC1.
SST 09843 ± 18020
(6) Connect the short pin to DLC1.
(e) Using TOYOTA break±out±box and TOYOTA hand±held
tester, measure the ECU terminal values.
(1) Hook up the TOYOTA hand±held tester and
TOYOTA break±out±box to the vehicle.
(2) Read the ECU input/output values by following the
prompts on the tester screen.
HINT:
TOYOTA hand±held tester has a ºSnapshotº function. This re-
cords the measured values and is effective in the diagnosis of
intermittent problems.
Please refer to the TOYOTA hand±held tester/TOYOTA break±
out±box operator's manual for further details.
