ON-VEHICLE INSPECTION
PROCEDURE
1. INSPECT FUEL CUT OPERATION
(a) Start the engine and warm it up.
(b) Increase the engine speed to at least 3500 rpm.
(c) Use a sound scope to check for fuel injector assembly operation noise.
(d) Check that when the accelerator pedal is released, fuel injector assembly operation noise stops momentarily, and then resumes.
If the result is not as specified, check the fuel injector assembly, wiring and ECM.
2. VISUALLY INSPECT HOSES, CONNECTIONS AND GASKETS
(a) Check that there are no cracks, leaks or damage.
NOTICE:
If the result is not as specified, replace parts as necessary.
3. INSPECT EVAPORATIVE EMISSION CONTROL SYSTEM
(a) Connect the Techstream to the DLC3.
(b) Remove the V-bank cover sub-assembly.
(c) Slide the hose clip and disconnect the purge line hose from the purge VSV. |
|
(d) Start the engine and turn the Techstream on.
(e) Enter the following menus: Powertrain / Engine / Active Test / Activate the VSV for EVAP Control.
OK:
Tester Operation |
Specified Condition |
---|---|
EVAP VSV: OFF |
Purge VSV has no suction |
EVAP VSV: ON |
Purge VSV has suction |
(f) Connect the purge line hose to the purge VSV, and slide the hose clip to secure it.
(g) Install the V-bank cover sub-assembly.
4. INSPECT FUEL CUTOFF VALVE AND FILL CHECK VALVE
(a) Remove the fuel tank assembly.

|
(c) Install the fuel tank assembly with the fuel tank vent hose disconnected.
(d) Fill the fuel tank assembly with fuel.
(e) Apply pressure at 4 kPa (41 kgf/cm2, 0.58 psi) to the vent port of the fuel tank assembly.
HINT:
Check the amount of fuel left in the fuel tank assembly.
(f) Remove the fuel tank cap assembly, and check that the pressure decreases. If the pressure does not decrease, replace the fuel tank assembly. Text in Illustration

(g) Reconnect the fuel tank vent hose to the fuel tank assembly.
5. INSPECT AIR INLET LINE
(a) Disconnect the fuel tank vent hose from the charcoal canister assembly.

System Description
SYSTEM DESCRIPTION
1. DESCRIPTION
A part-time 2-speed VF2CM transfer uses a touch select 2-4 and high-low
system, enabling the driver to switch between 2WD, H4 and L4 modes by turning
the transfer position switch.
Through these switch signals, the 4 wheel drive control ECU actua ...

1. CHECK SLIDING ROOF ECU (SLIDING ROOF DRIVE GEAR SUB-ASSEMBLY)
(a) Disconnect the S50 sliding roof ECU (sliding roof drive gear sub-assembly)
connector.
(b) Measure the resistance and voltage according to the value(s) in the table
below.

HINT:
Using the Techstream to read the Data List allows the values or states of switches,
sensors, actuators and other items to be read without removing any parts. This non-intrusive
inspection can be very useful because intermittent conditions or signals ...
