2. USING HAND±HELD TESTER
(a) Connect the hand±held tester to the DLC3.
(b) Monitor the ECU data by following the prompts on the tester screen.
HINT:
Hand±held tester has a ºSnapshotº function which records the monitored data.
Refer to the hand±held tester operator's manual for further details.
3. DATA LIST
HINT:
From the DATA LIST displayed by the the hand±held tester, you can read the value of the switch, the sensor
and so on without removing parts. Reading the DATA LIST as the first step to troubleshooting is one way
to shorten labor time.
(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, read the ºDATA LISTº.

4. DTC CLEAR
(a) The following methods will erase the DTCs and freeze frame data.
(1) The hand±held tester can be used to erase the codes.
(2) Disconnecting the battery terminals or EFI No.1 fuse can also erase the codes (1AZ±FSE).
Disconnecting the battery terminals or EFI the fuse (1CD±FTV).
(b) After completing repairs, the DTC retained in the memory can be cleared by removing the EFI No.1
fuse for 1 minute or more with the ignition switch to the OFF position.
(c) Check that the normal code is displayed after connecting the fuse.
5. PROBLEM SYMPTOM CONFIRMATION (ROAD TEST)
(a) Inspect the SET switch.
(1) Push the main switch button to ON.
(2) Drive at a desired speed (40 km/h (25 mph) or high-
er).
(3) Push down the control switch to the SET/COAST
position.
(4) After releasing the switch, check that the vehicle
cruises at the desired speed.
(b) Inspect the 'ACC' switch.
(1) Push the main switch button to ON.
(2) Drive at a desired speed (40 km/h (25 mph) or high-
er).
(3) Check that the vehicle speed increases when the
control switch is pushed up to RES/ACC, and that
the vehicle cruises at the set speed when the switch
is released.
(4) Push the control switch to RES/ACC, and then im-
mediately release it. Check that the vehicle speed
increases by about 1.6 km/h (Tap±up function).

1. INSPECT BRAKE BOOSTER
(a) Airtightness check.
(1) Start the engine and stop it after 1 or 2 minutes. De-
press the brake pedal several times slowly.
HINT:
If the pedal can be depressed to the f;oor the first time, but on
the 2nd or 3rd time cannot be depreesed as far, the booster is
airtight.
(2) Depress the brake pedal while the engine is run-
ning, and stop the engine with the pedal depressed.
HINT:
If there is no change in the pedal reserve distance after holding
the pedal for 30 seconds, the booster is airtight.
(b) Operating check.
(1) Depress the brake pedal several times with the igni-
tion switch off and check that there is no change in
the pedal reserve distance.
(2) Depress the brake pedal and start the engine.
HINT:
If the pedal goes down slightly, operation is normal.
2. INSPECT VACUUM CHECK VALVE
(a) Inspect vacuum check valve.
(1) Slide the clip and disconnect the vacuum hose.
(2) Remove the vacuum check valve.
(3) Check that there is ventilation from the booster to
the engine, and no ventilation from the engine to the
booster.
(4) If any fault is found, replace the vacuum check
valve.
