PROBLEM SYMPTOMS TABLE
Perform troubleshooting of the circuit for the applicable problem symptom in the order given in the chart be-
low. Proceed to the page located for each circuit.
HINT:
Troubleshooting of the wireless door lock control system is based on the premise that the door lock
control system and theft deterrent system are operating normally. Accordingly, before troubleshooting
the wireless door lock control system, first make certain that the door lock control system and theft de-
terrent system are operating normally.
If the instruction ºProceed to next circuit inspection shown on matrix chartº is given in the flow chart
for each circuit, proceed to the circuit with the next highest number in the table to continue the check.
If the trouble still reappears even through there are no abnormalities in any of the other circuits, check
and replace the Wireless Door Lock ECU as the last step.

EMISSION CONTROL SYSTEM
PURPOSE
The emission control systems are installed to reduce the amount of HC, CO and NOx exhausted from the
engine ((3) and (4)), to prevent the atmospheric release of blow-by gas-containing HC (1) and evaporated
fuel containing HC being released from the fuel tank (2).
The function of each system is shown in these table:
SystemAbbreviationFunction
(1) Positive Crankcase Ventilation
(2) Evaporative Emission Control
(3) Three-Way Catalytic Converter
(4) Sequential Multiport Fuel Injection*PCV
EVAP
TWC
SFIReduces HC
Reduces evaporated HC
Reduces HC, CO and NOx
Injects a precisely timed, optimum amount of fuel for reduced exhaust
emissions
Remark: * For inspection and repair of the SFI system, refer to the SF section in this manual.

CONTROL SYSTEM
INSPECTION
1. INSPECT LINES AND CONNECTIONS
Visually check for loose connections, sharp bends or damage.
2. INSPECT FUEL TANK
Visually check for deformation, cracks or fuel leakage.
3. INSPECT FUEL TANK CAP
Visually check if the cap and/or gasket are deformed or dam-
aged.
If necessary, repair or replace the cap.
4. INSPECT EVAP SYSTEM LINE
(a) Warm up the engine and stop the engine.
Allow the engine to warm up to normal operating tempera-
ture.
(b) Install a vacuum gauge (EVAP control system test equip-
ment vacuum gauge) to the EVAP service port on the
purge line.
(c) TOYOTA Hand-Held tester:
Forced driving of the VSV for the EVAP.
(1) Connect a TOYOTA hand-held tester to the DLC3.
(2) Start the engine.
(3) Push the TOYOTA hand-held tester main switch
ON.
(4) Use the ACTIVE TEST mode on the TOYOTA
hand-held tester to operate the VSV for the EVAP.
(d) If you have no TOYOTA Hand-Held Tester:
Forced driving of the VSV for the EVAP.
(1) Disconnect the VSV connector for the EVAP.
(2) Connect the positive (+) and negative (-) leads from
the battery to the VSV terminals for the EVAP.
(3) Start the engine.

(e) Check the vacuum at idle.
Vacuum:
Maintain at 0.368 - 19.713 in.Hg (5 - 268 in.Aq) for over
5 seconds
HINT:
If the vacuum does not change, you can conclude that the hose
connecting the VSV to the service port has come loose or is
blocked, or the VSV is malfunctioning.
(f) TOYOTA Hand-Held Tester:
Conclude forced driving of the VSV for the EVAP.
(1) Stop the engine.
(2) Disconnect the TOYOTA hand-held tester from the
DLC3.
(g) If you have no TOYOTA Hand-Held Tester:
Conclude forced driving of the VSV for the EVAP.
(1) Stop the engine.
(2) Disconnect the positive (+) and negative (-) leads
from the battery from the VSV terminals for the
EVAP.
(3) Connect the VSV connector for the EVAP.
(h) Disconnect the vacuum gauge from the EVAP service
port on the purge line.
(i) Connect a pressure gauge to the EVAP service port on
the purge line.
(j) Check the pressure.
(1) Close off the air drain hose at the marked position
of the canister with a hose clipper or similar instru-
ment.
(2) Add the pressure (13.5 - 15.5 in.Aq) from the EVAP
service port.
Pressure:
2 minutes after the pressure is added, the gauge
should be over 7.7 - 8.8 in.Aq.
HINT:
If you can't add pressure, you can conclude that the hose con-
necting the VSVcanisterfuel tank has slipped off or the
VSV is open.

(3) Check if the pressure decreases when the fuel tank
cap is removed while adding pressure.
HINT:
If the pressure does not decrease when the filler cap is re-
moved, then you can conclude that the hose connecting the
service port to the fuel tank is blocked, etc.
(k) Disconnect the pressure gauge from the EVAP service
port on the purge line.
5. CHECK AIRTIGHTNESS IN FUEL TANK AND FILLER
PIPE
(a) Disconnect the EVAP line hose from the charcoal canister
side and then pressurize and make the internal pressure
in the fuel tank 4 kPa (41 gf/cm
2, 0.58 psi).
(b) Check that the internal pressure of the fuel tank can be
hold for 1 minute.
(c) Check the connected portions of each hose and pipe.
(d) Check the installed parts on the fuel tank.
If there is no abnormality, replace the fuel tank and filler pipe.
(e) Reconnect the EVAP line hose to the charcoal canister.
6. INSPECT FUEL CUTOFF VALVE AND FILL CHECK
VA LV E
(a) Disconnect the purge line hose and EVAP line hose from
the charcoal canister.
(b) Plug the cap to the air drain hose.
(c) Pressurize 4 kPa (41 gf/cm
2, 0.58 psi) to the purge port
and check that there is ventilation through the EVAP line
hose.
HINT:
In the condition that the fuel is full, as the float value of the fill
check valve is closed and has no ventilation, it is necessary to
check the fuel amount (volume).
(d) Check if there is any struck in the vent line hose and EVAP
line hose.
If there is no stuck in hoses, replace the fuel cutoff valve and fill
check valve.
(e) Reconnect the purge line hose and EVAP line hose to the
charcoal canister.
