Toyota 53310100.cuw: Camry 1MZ-FE Engine Control Calibration
Learn how Toyota calibration 53310100.cuw relates to the 2002 Camry V6 engine control module and later service bulletins.
53310100.cuw is associated with an engine control module calibration for the 2002 Toyota Camry with the 1MZ-FE V6 engine. The engine control module manages engine operation using sensor information to regulate functions such as fuel delivery and ignition timing.
The calibration identifier 53310100 appears in Toyota service records as a previous calibration. That status identifies it as an earlier version considered by the bulletins, not as the updated software described in them.
Vehicle-speed and diagnostic context
Toyota service bulletin T-SB-0072-10 lists calibration 53310100 as previous in a bulletin addressing an illuminated malfunction indicator light and diagnostic trouble code P0500. P0500 concerns the vehicle-speed signal, which the engine control module uses as part of its assessment of vehicle operation. The bulletin covers 2002 and 2003 Camry models, but that multi-model scope does not establish exact fitment for this calibration in every listed vehicle.
The same identifier also appears as a previous calibration in bulletin EG013-01, associated with diagnostic code U140E. These records provide useful context for diagnosis and calibration identification. They do not establish that 53310100 itself introduced the changes discussed in either bulletin.
Identifying the calibration
Bulletins T-TCI-1130 and EG017-02 specifically associate the previous calibration with the 2002 Camry, the 1MZ-FE engine and the engine control module. The complete identifier matters when distinguishing this entry from other Toyota calibration records. The filename does not name a modified variant or a separate added feature.
