BRAKE
INSPECTION
1. INSPECT BRAKE LINE PIPES AND HOSES
HINT:
Inspect in a well−lighted area. Inspect the entire circumference
and length of the brake hoses using a mirror as required. Turn
the front wheels fully right or left before inspecting the front
brake.
(a) Check all brake lines and hoses for:
Damage
Wear
Deformation
Cracks
Corrosion
Leaks
Bends
Twists
(b) Check all clamps for tightness and connections for leak-
age.
(c) Check that the hoses and lines are clear of sharp edges,
moving parts and the exhaust system.
(d) Check that the lines installed in grommets pass through
the center of the grommets.
2. INSPECT FRONT BRAKE PADS AND DISCS
(2WD: See page BR−22)
(4WD: See page BR−25)
HINT:
If a squealing or scraping noise occurs from the brake during
driving, check the pad wear indicator.
If there are traces of the indicator contacting the disc rotor, the
disc pad should be replaced.
3. INSPECT REAR BRAKE LININGS AND DRUMS
(2WD: See page BR−42)
(4WD: See page BR−48)

(3) Return the No.1 gear shifting rod 2 notches to N
position.
(4) Set the shift lever to N position.
(5) While holding the shift lever lightly toward the R
position side, adjust the No.1 gear shifting rod nut.
(6) Tighten the No.1 gear shifting rod nut.
Torque: 25 N·m (260 kgf·cm, 19 ft·lbf)
(7) Start the engine and make sure that the vehicle
moves forward when shifting the lever from the N to
D position and reverses when shifting it to the R
position.
(g) Inspect and adjust the park/neutral position.
Check that the engine can be started with the shift lever
only in the N or P position, but not in other positions.If it
is not as stated above, carry out the following adjustment
procedure.
(1) Loosen the park/neutral position switch bolt and set
the shift lever to the N position.
(2) Align the groove and neutral basic line.
(3) Hold in position and tighten the bolt.
Torque: 13 N·m (130 kgf·cm, 10 ft·lbf)
(h) Check the idle speed.
Idle speed (In N position and air conditioner OFF):
3RZ−FE: 700 ± 50 rpm
5VZ−FE: 700 ± 50 rpm
6. MECHANICAL SYSTEM TESTS
(a) Measure the stall speed.
The object of this test is to check the overall performance of the transmission and engine by measuring
the stall speeds in the D and R positions.
NOTICE:
Do the that at normal operating fluid temperature 50 − 80°C (122 − 176°F)
Do not continuously run this test longer than 5 seconds.
To ensure safety, conduct this test in a wide, clear, level area which provides good traction.
The stall test should always be carried out in pairs. One technician should observe the condi-
tions of wheels or wheel stoppers outside the vehicle while the other is doing the test.
(1) Chock the 4 wheels.
(2) Connect an OBD II scan tool or TOYOTA hand−held tester to DLC3.
(3) Fully apply the parking brake.
(4) Keep your left foot pressed firmly on the brake pedal.
(5) Start the engine.
(6) Shift into the D position. Press all the way down on the accelerator pedal with your right foot.
Quickly read the stall speed at this time.
Stall speed:
3RZ−FE: 1,950 ± 150 rpm
5VZ−FE: 2,150 ± 150 rpm
(7) Do the same test in R position.
Stall speed:
3RZ−FE: 1,950 ± 150 rpm
5VZ−FE: 2,150 ± 150 rpm

Stop Light Switch Circuit
CIRCUIT DESCRIPTION
The purpose of this circuit is to prevent the engine from stalling, while driving in lock−up condition, when
brakes are suddenly applied.
When the brake pedal is operated, this switch sends a signals to the ECM. Then the ECM cancels operation
of the lock−up clutch while braking is in progress.

PRE−CHECK
1. DIAGNOSIS SYSTEM
(a) Check the indicator light.
When the ignition switch is turned ON, check that the ABS
warning light goes on for 3 seconds.
HINT:
If the indicator check result is not normal, proceed to trouble-
shooting for the ABS warning light circuit (See page DI−354).
(b) Check the DTC.
(1) Using SST, connect terminals Tc and E
1 of the
DLC1.
SST 09843−18020
(2) Disconnect the short pin from the DLC1.
(3) Turn the ignition switch ON.
(4) Read the DTC from the ABS warning light on the
combination meter.
HINT:
If no code appears, inspect the diagnostic circuit or ABS
warning light circuit (See page DI−354 or DI−358).
As an example, the blinking patterns for normal code and
codes 11 and 21 are shown on the left.
(5) Code are explained in the code table on page
DI−326.
(6) After completing the check, disconnect terminals Tc
and E
1, and turn off the display.
If 2 or more malfunctions are indicated at the same time the low-
est numbered DTC will be displayed 1st.

DLC1 and remove the short pin from the DLC1.
SST 09843−18020
(2) Turn the ignition switch ON.
(3) Clear the DTC stored in ECU by depressing the
brake pedal 8 or more times within 3 seconds.
(4) Check that the warning light shows the normal
code.
(5) Remove the SST from the terminals of the DLC1.
SST 09843−18020
(6) Connect the short pin to the DLC1.
HINT:
Cancellation can also be done by removing the ECU−B fuse,
but in this case, other memory systems will also be cancelled
out.
(d) Using TOYOTA brake−out−box and TOYOTA hand−held
tester, measure the ECU terminal value.
(1) Hook up the TOYOTA hand−held tester and
TOYOTA break−out−box to the vehicle.
(2) Read the ECU input/output values by following the
prompts on the tester screen.
HINT:
TOYOTA hand−held tester has a ”Snapshot” function. This re-
cords the measured values and is effective in the diagnosis of
intermittent problems.
Please refer to the TOYOTA hand−held tester/TOYOTA break−
out−box operator’s manual for further details.
2. SPEED SENSOR SIGNAL AND DECELERATION SEN-
SOR CHECK
(a) Check the speed sensor signal.
(1) Turn the ignition switch OFF.
(2) Using SST, connect terminals Ts and E
1 of the
DLC1.
SST 09843−18020
(3) Start the engine.

See the list of DTC on page DI−326.
If every sensor is normal, a normal code is output (A cycle
of 0.25 sec. ON and 0.25 sec. OFF is repeated).
If 2 or more malfunction are indicated at the same time,
the lowest numbered code will be displayed 1st.
(9) After doing the check, disconnect terminals Ts and
E
1, Tc and E1 of the DLC1, and ignition switch
turned OFF.
