27 Correctly reinstall or replace fuel tank cap.
HINT:

When reinstalling the fuel tank cap, tighten it until a few click sounds are heard.

When replacing the fuel tank cap, use a fuel tank cap that meets OEM specifications, and install it until
a few click sounds are heard.
NEXT Go to step 37.
28 Replace fuel tank cap.
HINT:
When installing the fuel tank cap, tighten it until a few click sounds are heard.
NEXT Go to step 37.
29 Repair EVAP leak part.
(a) Prepare a rubber hose with a 15 to 18.5 mm inside diame-
ter.
(b) Reinstall the fuel tank cap.
(c) Disconnect the atmospheric side hose of the pump mod-
ule.
(d) Connect the rubber tube to the pump module.
(e) Using SST, pinch the rubber tube to close the canister
passage to air.
SST 00002±6872A
(f) Connect a pressure gauge (SST) to the service port
(green cap near the air cleaner box).
(g) Pressurize the EVAP system to 3.2 to 3.7 kPa (24 to 28
mmHg).
(h) Apply soapy water to the piping and connecting parts of
the EVAP system. Look for areas where bubbles appear.
This indicates leaking points.
(i) Repair or replace leaking point.
HINT:

If the system has leaks, a whistling sound will be heard.

Disconnect the hose between the canister and the fuel
tank from the canister. Close the canister hose connected
to the fuel tank, and conduct an inspection. In this way, the
fuel tank can be excluded as an area suspected of caus-
ing fuel leaks.
NEXT Go to step 36.

(h) Remove the overflow plug and check the fluid level.
Standard:
When ATF overflowsATF level is higher than specification
(Go to step (k))
When ATF does not overflow
ATF level is equal to or lower than
specification
(Go to step (i))
HINT:

ºOverflowº indicates the condition under which ATF
drains out from the overflow tube.

The capacity of the overflow tube is approximately 3 cc.
If the amount of drained ATF is little, only the fluid remain-
ing in the tube has drained out. This condition is not con-
sidered as ºoverflowº.
(i) Remove the refill plug.
(j) Add ATF through the refill hole until it flows out from the
overflow hole.
Fluid type: Toyota genuine ATF WS
(k) When the draining ATF has become a trickle, install the
overflow plug with a new gasket.
(l) Install the refill plug if removed.
(m) Lower the vehicle.
(n) Turn the ignition switch off to stop the engine.
2. CHECK FLUID CONDITION
If the fluid smells burnt or is black, replace it (see step 6).
3. INSPECT AND ADJUST SHIFT LEVER POSITION
(a) When shifting the shift lever from the N position to other
positions, check that the lever can be shifted smoothly
and accurately to each position and that the position indi-
cator comes on in accordance with the shift lever position.
If the indicator and shift lever position do not match, carry out
the following adjustment procedures.
(1) Remove the nut and disconnect the shift control
cable from the control shaft lever.
(2) Move the control shaft fully rearward.
(3) Return the control shaft lever 2 notches to the N
position.
(4) Set the shift lever to the N position.
(5) Connect the shift control cable and temporarily
install the control shaft lever nut.
(6) While holding the shift lever lightly toward the R
position side, tighten the control shaft lever nut.
