REVISION NOTICE:
April 1, 2005: 2004 ± 2005 model year ES 330 vehicles have been added to
Applicable Vehicles. Introduction and Note have been updated on page 1.
Calibration Identification Chart has been updated to include ES 330 calibration IDs.
August 6, 2003: There has been a change in Warranty Time.
Previous versions of this TSIB should be discarded.
To improve the transmission shift feeling during specific operating modes, the Engine
Control Module (SAE term: Powertrain Control Module/PCM) calibration has been
revised. These improvements include:
Reduced downshift lag when accelerating at speeds from 10 to 20 mph.
Less gear hunting when driving on/off accelerator pedal at 20 to 30 mph
(for example: during heavy rush±hour traffic).
Improved response rate during heavy acceleration from a stop.
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 1 of the
Repair Procedure).
Harsh ATM shifting may result if any Repair Procedure steps are omitted
(specifically steps 2 and 4 of ªFlash Reprogram ECMº on page 6).
2002 ± 2003 model year ES 300 vehicles.

NOTE:
2004 model year ES 330 vehicles, which have been flash reprogrammed using the
procedures in this TSIB, will contain upgraded 2005 model year OBD II logic and will
require VIN input. Refer to the 2005 model year ES 330 Repair Manual information on
the Technical Information System (TIS) when checking Powertrain Diagnostic Trouble
Codes (DTCs) on 2004 model year ES 330 vehicles that have been reprogrammed.
2002 model year ES 300 vehicles, which have been flash reprogrammed using the
procedures in this TSIB, will contain upgraded 2003 model year OBD II logic. Refer to
the 2003 model year ES 300 Repair Manual information on the Technical Information

If Calibration ID matches ªNew Calibration IDº as shown in Calibration Identification
Chart, this vehicle has already been programmed. Refer to TIS for diagnostic
procedures applicable to any stored DTCs.
3. If ECU calibration ID is not the same as the ªNew Calibration IDº listed previously,
proceed to Flash Reprogram ECM (PCM).

NOTE:
If the ªCheck Engineº light is ON when the ignition is turned back on to begin the
reprogramming process, a scan tool cable problem exists. Refer to TSIB No.

1. INSPECT TIRE
(a) Check the tires for wear and proper inflation pressure.
Cold tire inflation pressure:
Tire sizeFront, Rear
kPa (kgf/cm2, psi)
P215/60R16 94V200 (2.0, 29)
P215/55R17 93V210 (2.1, 30)
(b) Using a dial indicator, check the tire runout.
Tire runout: 1.0 mm (0.039 in.) or less
2. ROTATE TIRES
HINT:

Rotate tires as shown in illustration (A) if a spare tire is not
included in the rotation.

Rotate tires as shown in illuatration (B) if a spare tire is in-
cluded in the rotation.
3. INSPECT WHEEL BALANCE
(a) Check and adjust the Off-the-car balance.
(b) If necessary, check and adjust the On-the-car balance.
Imbalance after adjustment: 8.0 g (0.018 lb) or less
4. INSPECT BEARING LOOSENESS (SEE PAGE 30-2)
5. INSPECT AXLE HUB RUNOUT (SEE PAGE 30-2)
