(h) Carefully observe all specifications for bolt tightening
torques. Always use a torque wrench.
(i) Use of special service tools (SST) and special service ma-
terials (SSM) may be required, depending on the nature
of the repair. Be sure to use SST and SSM where speci-
fied and follow the proper work procedure. A list of SST
and SSM can be found in the preparation part at the front
of each section in this manual.
(j) When replacing fuses, be sure the new fuse has the cor-
rect amperage rating. DO NOT exceed the rating or use
one with a lower rating.
(k) Care must be taken when jacking up and supporting the
vehicle. Be sure to lift and support the vehicle at the prop-
er locations (See page IN-8).
(1) If the vehicle is to be jacked up only at the front or
rear end, be sure to block the wheels at the opposite
end in order to ensure safety.
(2) After the vehicle is jacked up, be sure to support it
on stands. It is extremely dangerous to do any work
on a vehicle raised on a jack alone, even for a small
job that can be finished quickly.

(c) Install the antenna feeder at least 20 cm (7.87 in.) away from the ECU and sensors of the vehicle's
electronics systems. For details about ECU and sensors locations, refer to the section on the applica-
ble component.
(d) Do not wind the antenna feeder together with the other wiring. As much as possible, also avoid running
the antenna feeder parallel with other wire harnesses.
(e) Confirm that the antenna and feeder are correctly adjusted.
(f) Do not install powerful mobile communications system.
4. FOR USING OBDII SCAN TOOL OR TOYOTA HAND-HELD TESTER
Observe the following for safety reasons:

Before using the OBDII scan tool or TOYOTA hand-held tester, the OBDII scan tool's instruction
book or TOYOTA hand-held tester's operator manual should be read thoroughly.

Be sure to route all cables securely when driving with the OBDII scan tool or TOYOTA hand-held
tester connected to the vehicle. (i.e. Keep cables away from feet, pedals, steering wheel and shift
lever.)

Two persons are required when test driving with the OBDII scan tool or TOYOTA hand-held tes-
ter, one person to drive the vehicle and one person to operate the OBDII scan tool or TOYOTA
hand-held tester.
5. FOR VEHICLES EQUIPPED WITH TRACTION CON-
TROL (TRAC) SYSTEM
When using a 2 wheel drum tester such as a speedometer tes-
ter or chassis dynamometer, etc., or jacking up the rear wheels
and driving the wheels, always push in the TRAC cut (ºTRAC
OFFº) switch and turn the TRAC system OFF.
(a) Confirm TRAC system is OFF
(1) Press the TRAC cut (ºTRAC OFFº) switch.
(2) Check that the TRAC OFF indicator light comes on
when the TRAC system is turned off by the TRAC
cut switch.
HINT:
The TRAC OFF indicator light should always operate right after
the engine is restarted.
(3) Begin measurements.

INSPECTION
1. INSPECT ECU-IG FUSE (Instrument panel J/B)
2. INSPECT PPS ECU CIRCUIT
(a) Disconnect the PPS ECU connector.
(b) Inspect the connector on wire harness side, as shown in
the illustration.

If the circuit is not as specified, check and replace the wire har-
ness.
*If the circuit is not as specified, inspect the speed sensor.
3. INSPECT PPS SOLENOID VALVE
(a) Disconnect the PPS solenoid connector.
(b) Measure the resistance between the terminals of the so-
lenoid 1 and 2.
Resistance: 6 - 11 W
If it is not as specified, replace the pressure control valve with
the solenoid valve.
(c) Check the PPS solenoid operation.
(1) Connect the battery positive terminal to the sole-
noid terminal 1.
(2) Connect the battery negative terminal to the sole-
noid terminal 2.
(3) Check that the solenoid makes a ºclicksº sound.
If it is faulty, replace the pressure control valve with the solenoid
valve.
NOTICE:

Do not apply voltage for more than 30 seconds to
avoid burning out the solenoid.

If repeating this step, wait until the solenoid cools
down enough that it can be touched by hand.
(d) Connect the PPS solenoid connector.
