(c) When not using the hand-held tester or OBD II scan tool:
(1) Using SST, connect terminals 13 (TC) and 4 (CG)
of the DLC3.
SST 09843-18040
NOTICE:

Make sure of the terminal numbers before connecting
them. Connecting wrong terminals can damage the
engine.

Turn OFF all electrical systems before connecting the
terminals.

Perform this inspection after the cooling fan motor is
turned OFF.

9. INSPECT COMPRESSION
(a) Warm up and stop the engine.
(b) Remove the intake air surge tank (see page 11-13).
(c) Disconnect the injector connectors.
(d) Remove the ignition coils.
(e) Remove the spark plugs.
(f) Inspect the cylinder compression pressure.
(1) Insert a compression gauge into the spark plug
hole.
SST 09992-00500
(2) Fully open the throttle.
(3) While cranking the engine, measure the compres-
sion pressure.
Compression pressure:
1.5 MPa (15.3 kgf/cm
2, 218 psi)
Minimum pressure:
1.0 MPa (10.2 kgf/cm
2, 145 psi)
Difference between each cylinder:
100 kPa (1.0 kgf/cm
2, 15 psi)
NOTICE:

Always use a fully-charged battery to obtain engine
speed of 250 rpm or more.

Check the other cylinder's compression pressure in
the same way.

This measurement must be done as quickly as pos-
sible.
(4) If the cylinder compression is low, pour a small
amount of engine oil into the cylinder through the
spark plug hole, then inspect again.
HINT:

If adding oil increases the compression, the piston rings
and/or cylinder bore may be worn or damaged.

If pressure stays low, the valve may be sticking or seated
improperly, or there may be leakage past the gasket.
10. INSPECT CO/HC
HINT:
The ECM properly controls the CO/HC concentration in the emission gas.
(a) Start the engine.
(b) Run the engine at 2,500 rpm for approximately 180 seconds.
(c) Insert the CO/HC meter testing probe at least 40 cm (1.3 ft) into the tailpipe during idling.
(d) Check the CO/HC concentration at idle and/or at 2,500 rpm.
HINT:
When doing the 2 mode (with the engine is at idle and at 2,500 rpm) tests, these measuring order are pre-
scribed by the applicable local regulations.
If the CO/HC concentration does not comply with the regulations, troubleshoot in the order given below.
(1) Check the heated oxygen sensor operation (see page 05-126).

(j) If you have the hand-held tester:
Force the VSV for CCV to operate.
(1) Connect the hand-held tester to the DLC3.
(2) Turn the ignition switch ON.
(3) Turn the hand-held tester ON.
(4) Use the ACTIVE TEST mode on the hand-held tes-
ter to operate the VSV for CCV.
NOTICE:
Do not start the engine during this operation.
HINT:
If the check is not completed within 10 minutes, the forced close
of the VSV for CCV will be tested.
(k) If you have no hand-held tester:
Force the VSV for CCV to operate.
(1) Disconnect the VSV for CCV connector.
(2) Connect the positive (+) and negative (-) leads of
the battery to the VSV for CCV terminals.
(l) Check the pressure.
(1) Add the pressure (13.5 to 15.5 in.Aq) from the
EVAP service port.
Pressure:
2 minutes after the pressure is added, the gauge
should be over 7.7 to 8.8 in.Aq.
HINT:
If you cannot add the pressure, it can be concluded that the
hose which connects the VSV for EVAP canister fuel tank is
slipped off or the VSV is open.
(2) Check if the pressure decreases when the fuel tank
cap is removed while adding the pressure.
HINT:
If the pressure does not decrease when the filler cap is re-
moved, it can be concluded that the hose which connects the
service port to the fuel tank is blocked, etc.
(m) If you have the hand-held tester:
Return to the normal VSV for CCV operation.
(1) Turn the ignition switch ON.
(2) Disconnect the hand-held tester from the DLC3.
(n) If you have no hand-held tester:
Return to the normal VSV for CCV operation.
(1) Disconnect the positive (+) and negative (-) leads
of the battery to the VSV for CCV terminals.
(2) Reconnect the VSV for CCV connector.

The following procedures are recommended to maintain windshield wiper
blade performance.
1998 ± 2006 model year Lexus vehicles.
OP CODEDESCRIPTIONTIMEOFPT1T2
N/ANot Applicable to Warranty±±±±
Recommendations for Windshield Wiper Maintenance, Cleaning, and Use:
1. Scheduled Maintenance
Check wiper rubber blades every 4 ± 6 months or 7,500 miles for wear, cracking,
and contamination.
Clean glass and rubber wiper blades if blades are not clearing glass adequately.
If this does not correct the problem, then replace the rubber elements.
2. Cleaning Procedure
Wiper Rubber: Bugs, dirt, sap, and road grime on blades will cause streaking.
Clean wiper rubber of road and environmental debris using cloth or paper towel
soaked with windshield washer fluid or mild detergent.
DO NOT USE fuel, kerosene, or petroleum based products to clean rubber
wiper blades.
Windshield: Bugs, sap, road grime, and car wash wax treatments decrease
wiper performance.
Rinse windshield with water and apply non±abrasive cleaner, such as Bon±Ami
(www.faultless.com), with a sponge.
NOTE:
Make sure to use plenty of water with all powder based cleaners so the glass is
not scratched.

Failure to follow the recommendations indicated below could result in reduced
effectiveness of the seat belt restraint system in case of vehicle collision, causing
personal injury.
If your seat belt cannot be fastened securely because it is not long enough, a
personalized Seat Belt Extender is available from your Lexus dealer free of charge.
Please visit your local Lexus dealer so that the dealer can order the proper required
length extender. Bring the heaviest coat you expect to wear for proper measurement and
selection of length. Additional ordering information is available at your Lexus dealer.
When the Seat Belt Extender is provided for rear seat positions (with automatic locking
retractor), make sure that the retractor is locked when in use.
To connect the extender to the seat
belt, insert the tab into the seat belt
buckle so that the buckle-release
buttons of the extender and the seat
belt are both facing outward as shown.
You will hear a click when the tab locks
into the buckle.
When not in use, remove the extender
and store in the vehicle for future use.
CAUTION:
On vehicles equipped with SRS ± Occupant Classification System (OCS)*, it is
critical that the extender tab be buckled into the buckle AFTER the occupant sits
down in the seat.
Leaving extender installed in the buckle before sitting down will cause the OCS to be
in the ªairbag offº or disarmed state.
* OCS will enable or disable the passenger front and side airbags based on passenger weight and seat belt
latch position classifying the passenger as a child or adult.
CAUTION:
When using the Seat Belt Extender, observe the following. Failure to follow these
instructions could result in reduced effectiveness of the seat belt restraint system in
case of vehicle accident, increasing the chance of personal injury.
Never use the Seat Belt Extender if you can COMFORTABLY fasten the seat belt
without it.
The Seat Belt Extender must never be used with any child safety seats.
Remember that the extender provided for you may not be safe when used on a
different vehicle, for another person or for a different seating position than the one
originally intended.September 29, 2004
