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).

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.
Trouble AreaSee page

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.

5. ACTIVE TEST
HINT:
Performing the ACTIVE TEST using the hand-held tester allows the relay and actuator, etc. to operate with-
out removing any parts. Performing the ACTIVE TEST as the first step of troubleshooting is one of the meth-
ods to shorten labor time.
It is possible to display the DATA LIST during the ACTIVE TEST.
(a) Connect the hand-held tester to the DLC3.
(b) Turn the ignition switch to the ON position.
(c) According to the display on the tester, perform the ºACTIVE TESTº.
HINT:
Ignition switch must be turned to the ON position to proceed to the ACTIVE TEST using the hand-held tester.

6. FREEZE FRAME DATA
HINT:

Whenever a DTC is detected or the ABS operates, the skid control ECU stores the current vehicle (sen-
sor) state as freeze frame data.

The skid control ECU stores the number of times (maximum: 31) the ignition switch has been turned
from off to the On position since the last time ABS was activated. However, if the vehicle was stopped
or at low speed (4.3 mph (7 km/h) or less), or if a DTC is detected, the skid control ECU will not count
the number since then.

Freeze frame data at the time the ABS operates:
The skid control ECU stores and updates data whenever the ABS system operates.
When the ECU stores data at the time a DTC is detected, the data stored when the ABS operated is
erased.

Freeze frame data at the time a DTC is detected:
When the skid control ECU stores data at the time a DTC is detected, no updates will be performed
until the data is cleared.
(a) Connect the Hand-held tester to the DLC3.
(b) Turn the ignition switch to the ON position.
(c) From the display on the tester, select the ºFREEZE FRAME DATAº.
