ON±VEHICLE INSPECTION
1. INSPECT FOR LEAKAGE OF REFRIGERANT
(a) Remove the console box assembly.
(b) Remove the glove compartment door.
(c) Remove the lower No. 2 finish panel.
(d) Remove the heater to register duct No. 4.
(e) Remove the lower LH finish panel.
(f) Remove the lower cover (See page BO±89).
(g) Remove the blower controller.
(1) Disconnect the connector.
(2) Remove the 2 screws and blower motor linear con-
troller.
(h) Using a gas leak detector, check for leakage.
If there is leakage, check the tightening torque at the joints or
check the evaporator.
(i) Install the blower motor linear controller with the 2 screws.
(j) Install the lower cover.
(k) Install the lower LH finish panel.
(l) Install the lower No.2 finish panel.
(m) Install the glove compartment door (See page BO±97).
2. INSPECT EXPANSION VALVE
(a) Set the manifold gauge set.
(b) Run the engine.
(c) Check quantity of gas with the sight glass in refrigeration
cycle.
(1) Run the engine at 1,500 rpm for at least 5 minutes.
(2) Then check that the high pressure reading is 1.37
to 1.57 Mpa (14 to 16 kgm/cm
2, 199 to 228 psi).
(d) Check the expansion valve.
If the expansion valve is faulty, the low pressure reading will
drop to 0 kPa (0 kgf/cm
2, 0 psi).
HINT:
When the low pressure reading drops to 0 kPa (0 kgf/cm
2, 0
psi), there is no difference in temperature between the IN and
OUT sides of the receiver.
3. INSPECT THERMISTOR RESISTANCE
(a) Disconnect the connector.
(b) Measure the resistance between terminals.
Standard resistance: 1,500 W at 25°C (77°F)
If resistance is not as specified, replace the thermistor.

Your vehicle is supplied with the two
kinds of keys.
1. Master keys (black)ÐThese keys work
in every lock. Your Toyota dealer will
need one of them to make a new key
with a built±in transponder chip.
2. Sub key (gray)ÐThis key will not work
in the glove box.
A transponder chip for engine immobilizer
system has been placed in the head of
the master and sub keys. These chips are
needed to enable the system to function
correctly, so be careful not to lose these
keys. If you make your own duplicate key,
you will not be able to cancel the system
or start the engine.To protect items locked in the glove box
when using valet parking, leave the sub
key with the attendant.
Since the side doors can be locked with-
out a key, you should always carry a
spare key in case you accidentally lock
your keys inside the vehicle.NOTICE
When using a key containing a trans-
ponder chip, observe the following
precautions:
When starting the engine, do not
use the key with a key ring resting
on the key grip and do not press
the key ring against the key grip.
Otherwise the engine may not start,
or may stop soon after it starts.
