TSIB UPDATE NOTICE:
The information contained in this TSIB supercedes TSIB No. BO004-98.
TSIB No. BO004-98 is now obsolete and should be discarded.
Beginning in 1997, Lexus introduced side airbags for the LS 400. Starting with 1998,
all Lexus vehicles are equipped with side airbags as standard equipment.
Lexus does NOT recommend replacement of original seat covers* with non-Lexus leather
or other seat cover materials due to the following:
Seat covers NOT recommended by Lexus may affect side airbag performance, in
general or in part, during an accident.
Modifications that negatively affect side airbag performance can result in severe
occupant injuries.
Seat covers are an integral part of this safety system. Replacing original seat covers*
with non-Lexus leather or other seat cover materials may compromise the
effectiveness of this safety system.
The design of the seat is complex, integrating safety and strength with comfort
and luxury.
*NOTE:
Lexus original seat covers that were NOT designed for side airbag equipped seats
cannot be used due to the effect on proper airbag performance.
Lexus strongly discourages modifying original equipment seats that have
side airbags.
Additionally, Lexus strongly advises against the installation or use of aftermarket
seat covers, which could impair the performance of the side airbags in the event of
an accident.
All 1997 ± 2006 model year Lexus vehicles.

Under certain driving conditions, some 2004 and 2005 model year ES 330 vehicles may
exhibit a M.I.L. ªONº with at least one of the following DTCs:
P0031 (Oxygen Sensor Heater Control Circuit Low [Bank 1, Sensor 1])
P0051 (Oxygen Sensor Heater Control Circuit Low [Bank 2, Sensor 1])
P2238 (Oxygen Sensor Pumping Current Circuit Low (for A/F Sensor)
[Bank 1, Sensor 1])
P2241 (Oxygen Sensor Pumping Current Circuit Low (for A/F Sensor)
[Bank 2, Sensor 1])
The A/F sensor manufacturing process and the Engine Control Module (ECM)
(SAE term: Powertrain Control Module/PCM) logic have been modified to improve
these conditions.
NOTE:
Version 12.01a or later Diagnostic Tester software is required to perform
this procedure.
Before proceeding, verify the ECM (PCM) calibration has NOT been updated
by checking for the Authorized Modifications Label (shown in step 2 of the
Repair Procedure).
