TIRE PRESSURE WARNING SYSTEM
PRECAUTION
1. TIRE PRESSURE WARNING SYSTEM PRECAUTION
(a) When the tire pressure warning lamp comes on, immedi-
ately check the air pressure of all tires and adjust to the
specified pressure.
Specified Value
Front210 kpa (2.1 kgf/cm2, 30 psi)
Rear210 kpa (2.1 kgf/cm2, 30 psi)
(b) This system requires initializing after changing tires or
wheels, or after rotating the tires (see page 28-1).
Set tire pressure within the specified range before initializ-
ing. If the tire air pressure is not within the specified range,
the tire pressure warning system will not function.
(c) In the following cases, the system may not operate nor-
mally.

A compact spare tire, snow tires, or tire chains are
used.

The tire pressure is excessively higher than speci-
fied, or tire pressure suddenly drops due to bursting
or other causes.

The vehicle is driven on a slippery road surface
such as rough or frozen roads.

The vehicle speed is 19 mph (30 km/h) or less or
more than 62 mph (100 km/h) , and the driving dura-
tion is less than 5 minutes.

The tires differ in tread pattern or manufacture.

The tires are not the specified size.

The tread wear is very different among the installed
tires.

Rapid acceleration/deceleration or sharp turns is
continued.

Towing a trailer.

The loading is over the limit or imbalanced.

Initialization was not performed correctly after re-
placing or rotating tires or wheels.

The outside temperature is below 32F (0C) or
above 104F (40C).

(a) When a system malfunction occurs in the tire pressure warning system, the tire pressure warning lamp
blinks.
(b) The result of this diagnosis is stored in the skid control ECU.

PRECAUTIONS FOR REPAIRING BODY
STRUCTURE PANELS
1. HEAT REPAIR FOR BODY STRUCTURE
PANELS
Toyota prohibits the use of the heat repair method on body
structure panels when repairing a vehicle damaged in a col-
lision.
Panels that have high strength and rigidity, as well as a long
life span for the automobile body are being sought after.
At Toyota, in order to fulfill these requirement, we use high
tensile strength steel sheets and rust preventive steel
sheets on the body.
High tensile steel sheets are made with alloy additives and
a special heat treatment in order to improve the strength.
To prevent the occurrence of rust for a long period of time,
the surface of the steel is coated with a zinc alloy.
If a body structure parts are heat repaired with an acetylene
torch or other heating source, the crystalline organization of
the steel sheet will change and the strength of the steel
sheet will be reduced.
The ability of the body to resist rust is significantly lowered
as well since the rust resistant zinc coating is destroyed by
heat and the steel sheet surface is oxidized.
2. STRUCTURE PANEL KINKS
A sharp deformation angle on the panel that cannot be re-
turned to its original shape by pulling or hammering is
called a kink.
Since structure parts were designed to exhibit a 100% per-
formance when they were in their original shape, if they are
deformed in an accident, or if the deformed parts are re-
paired and reused, they become unable to exhibit the same
performance as intended in the design.
It is necessary to replace the part where the kink has oc-
curred.

INTRODUCTIONIN-17
3. IMPACT BEAM REPAIR
The impact beam and bracket are necessary and important
parts in maintaining a survival space for passengers in a
side collision.
For impact beam, we use special high tensile strength
steel.
The high tensile strength steel maintains its special crystal-
line organization by heat treatment or alloy additives.
Since these parts were designed to exhibit a 100% perfor-
mance when they were in their original shape, if they are
deformed in an accident, or if the deformed parts are re-
paired and reused, they become unable to exhibit the same
performance as intended in the design.
It is necessary to replace the door assembly when impact
beam or bracket is damaged.

PRE-CHECK
1. DIAGNOSIS SYSTEM
(a) Check the warning lights.
(1) Release parking brake lever.
NOTICE:
When releasing the parking brake, set the chocks to hold
the vehicle for safety.
HINT:
When the parking brake is applied or the level of the brake fluid
is low, the BRAKE warning light comes on.
(2) When the ignition switch is turned to the ON posi-
tion, check that the ABS warning light, BRAKE
warning light, VSC warning light, TRAC OFF indica-
tor light and SLIP indicator light remain on for
approx. 3 seconds.
HINT:

If the ECU has any stored DTCs, the ABS warning light,
VSC warning light and TRAC OFF indicator light come on.

If the indicator does not come on, inspect if the bulb is
blown out, and also the wire harness between the skid
control ECU and the combination meter.

If the indicator remains on, proceed to troubleshooting for
the light circuit below.

2. DTC CHECK/CLEAR (USING SST CHECK WIRE)
(a) Check DTCs.
(1) Using SST, connect terminals Tc and CG of the
DLC3.
SST 09843-18040
(2) Turn the ignition switch to the ON position.
(3) Read the DTC from the ABS warning light or VSC
warning light on the combination meter.
HINT:

If 2 or more malfunctions are detected at the same time,
the lowest numbered code will be displayed first.

If no code appears, inspect the diagnostic circuit, ABS
warning light circuit or VSC warning light circuit.

As an example, the blinking patterns for a normal system
code and codes 11 and 21 are shown on the left.
(4) Codes are explained in the code table on page
05-779.
(5) After completing the check, disconnect terminals Tc
and CG of the DLC3, and turn off the display.

(b) Clear DTCs.
(1) Using SST, connect terminals Tc and CG of the
DLC3.
SST 09843-18040
(2) Turn the ignition switch to the ON position.
(3) Clear the DTCs stored in the ECU by depressing the
brake pedal 8 or more times within 5 sec.
(4) Check that the ABS warning light and VSC warning
light shows normal blinking patterns.
(5) Remove the SST from the DLC3.
SST 09843-18040
HINT:
Cancellation cannot be preformed by removing the battery
cable or the ECU-IG fuse.
3. DTC CHECK/CLEAR (USING HAND-HELD TESTER)
(a) Check DTCs.
(1) Connect the hand-held tester to the DLC3.
(2) Turn the ignition switch to the ON position.
(3) Read the DTCs following the prompts on the tester
screen.
HINT:
Refer to the hand-held tester operator's manual for further de-
tails.
(b) Clear the DTCs.
(1) Connect the hand-held tester to the DLC3.
(2) Turn the ignition switch to the ON position.
(3) Operate the hand-held tester to erase the codes.
HINT:
Refer to the hand-held tester operator's manual for further de-
tails.
4. DATA LIST
HINT:
According to the DATA LIST displayed on the Hand-held tester, you can read the value and status of the
switch, sensor, actuator and so on without parts removal. Reading the DATA LIST as a first step of trouble-
shooting is one of the methods to shorten the labor time.
(a) Connect the Hand-held tester to the DLC3.
(b) Turn the ignition switch ON.
(c) From the display on the tester, read the ºDATA LISTº.
