Type: Compact Cap, 108 kPa
1. Remove coolant and any foreign
material on rubber points ªA,º ªB,º
and ªC.º
2. Check that points ªAº and ªBº
are not deformed, cracked,
or swollen.
3. Check that points ªBº and ªCº are not
stuck together.
4. Apply engine coolant to point ªBº
before using the radiator
cap tester.
Radiator Cap Tester:

5. Before installing the radiator cap
tester, use the applicable radiator cap
adaptor provided in the following SST
kits in conjunction with the radiator
cap tester:
SST P/N 09230±00030±02
(09231±10080±01) or
09230±00020±02 (09231±10060±01)
6. When using the radiator cap tester,
tilt it more than 30 degrees.
7. Pump the radiator cap tester
several times, and check the
maximum pressure.
Pumping speed: 1 pump/second
HINT:
Stop pumping when the valve opens
and read the gauge. The gauge must
be within the standard values listed
below when the pressure valve opens.
The cap is considered OK when the
pressure holds steady or falls very
slowly, but holds within the standard
values listed below for one minute.

ENTERING VIN DURING ECM (PCM)
REPLACEMENT AND/OR DTC P0630
Models:
All '04 ± '06 Models
TSIB REVISION NOTICE:
June 3, 2005: Content has been updated to include 2004 and 2006 model year
vehicles. Step 4 of the VIN Write Procedure (page 2) and step 3 of the VIN Read
Procedure (page 3) have been clarified to include RX 400h vehicles.
Previous versions of this TSB should be discarded.
All 2005 and subsequent model year Lexus vehicles have the VIN (Vehicle Identification
Number) stored in the Electronic Control Module (ECM) (SAE term: Powertrain Control
Module/PCM) non±volatile memory. The VIN is accessible on the data stream using the
Lexus Diagnostic Tester and can also be written to a new ECM (PCM) using a ªVIN
Read/Writeº utility.
Service ECMs (supply parts) are shipped without the VIN; therefore, as part of the ECM
(PCM) replacement procedure, the VIN must be written to the replacement ECM (PCM)
using the Diagnostic Tester utility function. Failure to write the VIN to the ECM (PCM) will
result in a M.I.L. ªONº condition and set DTC P0630: VIN Not Programmed or Mismatch ±
ECM (PCM).
It is very important to remember to enter the VIN on these vehicles. Vehicles with missing
VINs are subject to failing some state and local vehicle emissions Inspection and
Maintenance programs.
NOTE:
2004 model year vehicles which have been flash reprogrammed may contain updated
2005 model year OBD II logic. These vehicles will require VIN entry into the ECM (PCM)
after reprogramming.
2004 model year vehicles that have been flash reprogrammed.
All 2005 ± 2006 model year vehicles.

PASSENGER AIRBAG INDICATOR LAMP
Models:
'04 ± '05 ES 330 & RX 330
Technical Service
Information Bulletin
February 22, 2005
EL002-05
The passenger airbag indicator lamp may switch from ON to OFF for front seat
passengers weighing approximately less than 100 pounds, depending on their seating
position. It is important for the front seat passengers to know that proper operation of the
advanced frontal airbag system is highly dependent on the pressure placed on the seat
bottom. Situations that add or subtract sensed weight can result in occupant
misclassification. To minimize this situation:
Check seating posture.
± Passengers should be seated upright with their back against the seatback and
feet on the floor.
Check loading conditions.
± Extra weight from items such as bags or groceries or toys hanging on the
seatback can add to the sensed weight of the front seat passenger.
± A rear seat passenger lifting the front seat with their legs, objects placed under
the front seat, or the front seatback in contact with the rear seat can subtract from
the sensed weight of the front seat passenger.
If the passenger airbag indicator lamp continues to switch ON to OFF after checking the
above conditions, perform the following repair procedure.
NOTE:
The safest place for children is in the rear seat.
Please note that Lexus recommends
that you NEVER
install a rear±facing child restraint in the front passenger seat, even if
the passenger ªAirbag OFFº lamp is illuminated. Please refer to the Owner's Manual
for additional details.
