Toyota Yaris MED17.9.52 Firmware 10375517985MEB60S0
A catalog overview of the original Toyota Yaris 1.0i manual firmware for the Bosch MED17.9.52 engine controller.
10375517985MEB60S0 is listed as original engine control firmware for a Toyota Yaris 1.0i with a manual transmission. Its MED17.9.52 designation identifies a Bosch engine control unit, which manages engine operation rather than a separate transmission or body system.
What the engine controller does
The engine control unit uses sensor inputs to calculate commands for functions such as fuel injection, ignition timing and electronic throttle operation. These controls affect starting, idle quality, acceleration and emissions. The TC1782 designation in the catalog name identifies the controller’s processor family.
The calibration identifier distinguishes this file from other software records for similar controllers. The filename does not identify a particular repair or change made by this revision, so the controller’s general functions should not be read as a list of revision-specific improvements.
Original file identification
The catalog filename is Toyota Yaris 1.0i MT MED17.9.52 TC1782_10375517985MEB60S0-20201203-134259 PCM Flash original.bin. Here, MT identifies the manual-transmission application, and original.bin labels the file as an original binary rather than a named modified variant. The timestamp is part of the filename, while PCM Flash identifies the file’s catalog or readout context.
For diagnostic reference, the complete controller and calibration identifiers are more useful than the MED17 prefix alone. A shared controller family does not establish that another firmware file is suitable for the same vehicle.
