ENTERING VIN DURING ECM (PCM)

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.

EG019-05
Under certain driving conditions, some 2005 and 2006 model year ES 330 vehicles may
exhibit a M.I.L. ªONº condition with at least one of the following DTCs:
P0171 (System Too Lean [Bank 1])

P2195 (Oxygen [A/F] Sensor Signal Stuck Lean [Bank 1, Sensor 1])
P2197 (Oxygen [A/F] Sensor Signal Stuck Lean [Bank 2, Sensor 1])
The Air Fuel (A/F) sensor manufacturing process has been improved to correct this
condition. The following repair procedures should be used to properly diagnose and
repair the affected vehicles.

D.C.C. FUSE INSTALLATION DURING PDS
The D.C.C. fuse has been removed at the assembly plant to reduce parasitic current
draw in transit and storage.
The removed D.C.C. fuse (30 A) is stored in the blank space of the Junction Block in
the engine compartment. The D.C.C. fuse must be reinstalled during Pre±Delivery
Service (PDS) in the dealership as shown below.

NOTE:
Do not perform calibration of the compass in a place where the earth's magnetic
field is subject to interference by artificial magnetic fields (underground parking,
under a steel tower, between buildings, roof parking, near a railroad crossing, near
a large vehicle, etc.)
During calibration, do not operate electric systems (moon roof, power windows,
etc.) as they may interfere with the calibration.

BATTERY MAINTENANCE FOR
IN-STOCK VEHICLES & PRE-DELIVERY
Models:
All Models & Model Years Through Current
Technical Service
Information Bulletin
September 12, 2002
PG009-02
A battery in a stored vehicle is subject to conditions that can reduce its performance and
life. These conditions include storage period, temperature, parasitic drain, and battery
load. Because of these factors, battery inspection and maintenance are required in
order to ensure proper operation and optimal battery life.
As a matter of policy, Lexus does not provide battery warranty coverage for discharged
and/or failed batteries due to lack of maintenance; it is the dealer's responsibility to
maintain the specified state of charge of the vehicle's battery while in stock and assure
proper state of charge at delivery.
To eliminate customer service concerns due to an undercharged battery during the first
few weeks of ownership, all dealers should check battery state of charge and
recharge, if necessary, just prior to delivery (i.e., within 48 hours of delivery).
This new procedure will improve the new vehicle ownership experience by greatly
reducing the risk of having a low performance battery concern due to extended storage
periods and/or short engine run times prior to the vehicle sale.
All models and model years through current.
