Toyota Auris Firmware 89663-52J01: Engine Control Calibration
Explore Toyota Auris firmware 89663-52J01, its 2SZ engine-control catalog association, and the stock and MOD_e2 file labels.
Toyota firmware 89663-52J01 is cataloged as an engine-control calibration for the Auris with a 2SZ engine. Its associated main-flash files identify an engine control unit, or ECU, rather than a transmission or body controller.
The engine ECU uses sensor inputs to manage functions such as fuel injection and ignition timing. Its software helps the engine respond to the driver’s throttle request while operating within its designed limits. The catalog names identify this calibration and its application, but do not describe a change made specifically by revision 89663-52J01.
How the Auris files are identified
The entry 76F0038GD Main flash (736 KB) 89663-52J01- Auris 2SZ 89661-52J00.bin brings together the calibration identifier, the Auris 2SZ engine designation and the associated ECU part number 89661-52J00. Another file, Auris 76F0038GD Main flash (736 KB) 89663-52J01.bin, identifies the same calibration as a 736 KB main-flash image.
The 89663 number identifies the software calibration in this catalog, while 89661-52J00 is the associated ECU part number. Those identifiers serve different purposes when comparing a file with a vehicle’s ECU information.
Modified MOD_e2 variants
Several filenames carry the label MOD_e2, including Auris89661-52J00SW#89663-52J01 MOD_e2.bin and Auris89663-52J01SW#89663-52J01 MOD_e2.bin. The label distinguishes these files from the main-flash entries, but it does not state what was changed or establish a specific feature. The name alone does not establish that these files have identical contents.
The main-flash filenames do not carry the modification label. They identify the calibration image, although the names alone do not verify whether a particular file is factory-original or suitable for a particular vehicle.
