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 reserve travel after holding the pedal
for 30 seconds, the booster is air tight.

INSPECTION
1. CHECK THAT PEDAL HEIGHT IS CORRECT
Pedal height from asphalt sheet:
1MZ±FE: 161.8 ± 171.8 mm (6.370 ± 6.764 in.)
5S±FE: 156.8 ± 166.8 mm (6.173 ± 6.567 in.)
2. IF NECESSARY, ADJUST PEDAL HEIGHT
Loosen the lock nut and turn the stopper bolt until the height is
correct. Tighten the lock nut.
3. CHECK THAT PEDAL FREEPLAY AND PUSH ROD
PLAY ARE CORRECT
Push in on the pedal until the beginning of clutch resistance is
felt.
Pedal freeplay: 5.0 ± 15.0 mm (0.197 ± 0.591 in.)
Gently push the pedal until the resistance begins to increase a
little.
Push rod play at pedal top:
1.0 ± 5.0 mm (0.039 ± 0.197 in.)
4. IF NECESSARY, ADJUST PEDAL FREEPLAY AND
PUSH ROD PLAY
(a) Loosen the lock nut and turn the push rod until the free-
play and push rod play are correct.
(b) Tighten the lock nut.
(c) After adjusting the pedal freeplay, check the pedal height.
(d) Connect the air duct and install the lower finish panel.
5. INSPECT CLUTCH RELEASE POINT
(a) Pull the parking brake lever and install wheel stopper.
(b) Start the engine and idle the engine.
(c) Without depressing the clutch pedal, slowly shift the shift
lever into reverse position until the gears contact.
(d) Gradually depress the clutch pedal and measure the
stroke distance from the point the gear noise stops (re-
lease point) up to the full stroke end position.
Standard distance:
25 mm (0.98 in.) or more
(From pedal stroke end position to release point)
If the distance not as specified, do the following operation.

Inspect pedal height.

Inspect push rod play and pedal freeplay.

Bleed the clutch line.

Inspect the clutch cover and disc.

INSPECTION PROCEDURE
HINT:

If DTCs P0115 (Engine Coolant Temp. Circuit Malfunction) and P0116 (Engine Coolant Temp. Circuit
Range/Performance Problem) are output simultaneously, engine coolant temp. sensor circuit may be
open. Perform troubleshooting of DTC P0115 first.

Read freeze frame data using TOYOTA hand±held tester or OBD II scan tool. Because freeze frame
records the engine conditions when the malfunction is detected, when troubleshooting it is useful for
determining whether the vehicle was running or stopped, the engine warmed up or not, the air±fuel
ratio lean or rich, etc. at the time of the malfunction.

CONFIRMATION DRIVING PATTERN
(1) Connect the TOYOTA hand±held tester to the DLC3.
(2) Switch the TOYOTA hand±held tester from normal mode to check mode (See page DI±3).
(3) Start the engine and warm it up with all accessory switches OFF.
(4) Drive the vehicle at 50 ~ 65 km/h (31 ~ 40 mph) for 1 ~ 3 min. to warm up the heated oxygen sensor.
(5) Let the engine idle for 1 min.
(6) Perform steps (3) to (5) three times.
HINT:
If a malfunction exists, the MIL will light up during step (6).
NOTICE:
If the conditions in this test are not strictly followed, detection of the malfunction will not be possible.
If you do not have a TOYOTA hand±held tester, turn the ignition switch OFF after performing steps
(3) to (6), then perform steps (3) to (6) again.

SYSTEM CHECK DRIVING PATTERN
(1) Connect the OBD II scan tool or TOYOTA hand±held tester to the DLC3.
(2) Start and warm up the engine with all accessories switched OFF.
(3) Run the vehicle at 60 ~ 80 km/h (38 ~ 50 mph) for 3 min. or more.
(4) Idle the engine for about 2 min.
(5) Do steps (3) and (4) again.
(6) Stop at safe place and turn the ignition switch OFF.
(7) Do steps (2) to (5) again.
(8) Check the READINESS TESTS mode on the OBD II scan tool or TOYOTA hand±held tester.
If COMPL is displayed and the MIL does not light up, the system is normal.
If INCMPL is displayed and the MIL does not light up, run the vehicle again and check it.
HINT:
INCMPL is displayed when either condition (a) or (b) exists.
(a) The system check is incomplete.
(b) There is a malfunction in the system.
If there is a malfunction in the system, the MIL will light up after steps (2) to (5) above are done.

If DTC P0105 (Manifold Absolute Pressure/Barometric Pressure Circuit Malfunction), P0106 (Manifold
Absolute Pressure/Barometric Pressure Circuit Range/Performance Problem) and P0401 (Exhaust
Gas Recirculation Flow Insufficient Detected) are output simultaneously, perform troubleshooting of
DTC P0105 first.

If DTC P0401 (Exhaust Gas Recirculation Flow Insufficient Detected) and P0402 (Exhaust Gas Recir-
culation Flow Excessive Detected) are output simultaneously, perform troubleshooting of DTC P0402
first.
