ON-VEHICLE INSPECTION
1. CONNECT TOYOTA HAND-HELD TESTER:
(a) Connect the TOYOTA hand-held tester to the DLC3.
(b) Start the engine and run it at idle.
(c) Select the ACTIVE TEST mode on the TOYOTA hand-
held tester.
Please refer to the TOYOTA hand-held tester operator's
manual for further details.
2. INSPECT ACTUATOR MOTOR OPERATION
(a) With the motor relay ON, check the actuator motor opera-
tion noise.
(b) Turn the motor relay OFF.
(c) Depress the brake pedal and hold it for about 15 seconds.
Check that the brake pedal cannot be depressed.
(d) With the motor relay ON, check that the pedal does not
pulsate.
NOTICE:
Do not keep motor relay ON for more than 5 seconds con-
tinuously. When operating it continuously, set the interval
of more than 20 seconds.
(e) Turn the motor relay OFF and release the brake pedal.
3. INSPECT RIGHT FRONT WHEEL OPERATION
NOTICE:
Never turn ON the solenoid which is not described below.
(a) With the brake pedal depressed, perform the following
operations.
(b) Turn the SFRH and SFRR solenoid ON simultaneously,
and check that the pedal cannot be depressed.
NOTICE:
Do not keep solenoid ON for more than 10 seconds contin-
uously. When operating it continuously, set the interval of
more than 20 seconds.
(c) Turn the SFRH and SFRR solenoid OFF simultaneously,
and check that the pedal can be depressed.
(d) Turn the motor relay ON, and check that the pedal re-
turns.
NOTICE:
Do not keep motor relay ON for more than 5 seconds con-
tinuously. When operating it continuously, set the interval
of more than 20 seconds.
(e) Turn the motor relay OFF and release the brake pedal.
4. INSPECT OTHER WHEEL OPERATION
As in the same procedure, check the solenoids of other wheels.
HINT:
Left front wheel: SFLH, SFLR
Right rear wheel: SRRH, SRRR
Left rear wheel: SRLH, SRLR

BRAKE BOOSTER ASSEMBLY
ON-VEHICLE INSPECTION
1. OPERATING CHECK
(a) Depress the brake pedal several times with the engine off
and check that there is no change in the pedal reserve
distance.
(b) Depress the brake pedal and start the engine. If the pedal
goes down slightly, operation is normal.
2. AIR TIGHTNESS CHECK
(a) Start the engine and stop it after 1 or 2 minutes. Depress
the brake pedal several times slowly.
If the pedal goes down farthest the 1st time, but gradually rises
after the 2nd or 3rd time, the booster is air tight.
(b) Depress the brake pedal while the engine is running, and
stop the engine with the pedal depressed.
If there is no change in the pedal reverse travel after holding the
pedal for 30 seconds, the booster is air tight.

BRAKE PEDAL
ON-VEHICLE INSPECTION
1. CHECK PEDAL HEIGHT
Pedal height from asphalt sheet:
153.3 - 163.3 mm (6.035 - 6.429 in.)
If the pedal height is incorrect, adjust it.
2. IF NECESSARY, ADJUST PEDAL HEIGHT
(a) Remove the lower No. 1 instrument panel and lower LH
instrument panel insert (See page BO-87).
(b) Disconnect the connector from the stop light switch.
(c) Loosen the stop light switch lock nut and remove the stop
light switch.
(d) Loosen the push rod lock nut.
(e) Adjust the pedal height by turning the pedal push rod.
(f) Tighten the push rod lock nut.
Torque: 25 N´m (260 kgf´cm, 19 ft´lbf)
(g) Install the stop light switch.
(h) Connect the connector to the stop light switch.
(i) Push the brake pedal in 5 - 15 mm (0.20 - 0.59 in.), turn
the stop light switch to lock the nut in the position where
the stop light goes off.
(j) After installation, push the brake pedal in 5 - 15 mm (0.20
- 0.59 in.), check that stop light lights up.
(k) After adjusting the pedal height, check the pedal freeplay.
(l) Install the lower LH instrument panel insert and lower No.
1 instrument panel (See page BO-87).
3. CHECK PEDAL FREEPLAY
(a) Stop the engine and depress the brake pedal several
times until there is no more vacuum left in the booster.
(b) Push in the pedal by hand until the beginning of the resis-
tance is felt, then measure the distance.
Pedal freeplay: 1 - 6 mm (0.04 - 0.24 in.)
If incorrect, check the stop light switch clearance. If the clear-
ance is OK, then troubleshoot the brake system.
Stop light switch clearance:
0.5 - 2.4 mm (0.020 - 0.094 in.)
HINT:
The freeplay to the 1st resistance is due to the play between the
clevis and pin. This is magnified up to 1 - 6 mm (0.04 - 0.24 in.)
at the pedal.

4. CHECK PEDAL RESERVE DISTANCE
Release the parking brake.
With the engine running, depress the pedal and measure the
pedal reserve distance, as shown.
Pedal reserve distance from asphalt sheet at 490 N
(50 kgf, 110.2 lbf): More than 75 mm (3.0 in.)
If the reserve distance is incorrect, troubleshoot the brake sys-
tem.

CHARGING SYSTEM
ON-VEHICLE INSPECTION
CAUTION:

Check that the battery cables are connected to the
correct terminals.

Disconnect the battery cables when the battery is giv-
en a quick charge.

Do not perform tests with a high voltage insulation re-
sistance tester.

Never disconnect the battery while the engine is run-
ning.
1. CHECK BATTERY ELECTROLYTE LEVEL
Check the electrolyte quantity of each cell.
Maintenance-Free Battery:
If under the lower level, replace the battery (or add distilled wa-
ter if possible). Check the charging system.
Except Maintenance-Free Battery:
If under the lower level, add distilled water.
2. Except Maintenance-Free Battery:
CHECK BATTERY SPECIFIC GRAVITY
Check the specific gravity of each cell.
Standard specific gravity: 1.25 - 1.29 at 20°C (68°F)
If the specific gravity is less than specification, charge the bat-
tery.
3. Maintenance-Free Battery:
CHECK BATTERY VOLTAGE
(a) After having driven the vehicle and in the case that 20
minutes have not passed after having stopped the en-
gine, turn the ignition switch ON and turn on the electrical
system (headlight, blower motor, rear defogger etc.) for
60 seconds to remove the surface charge.
(b) Turn the ignition switch OFF and turn off the electrical sys-
tems.
(c) Measure the battery voltage between the negative (-)
and positive (+) terminals of the battery.
Standard voltage: 12.5 - 12.9 V at 20°C (68°F)
If the voltage is less than specification, charge the battery.
