Toyota and Lexus 895365001200-ii.cuw Firmware
A catalog reference for Toyota and Lexus firmware 895365001200-ii.cuw and its possible brake-control module family.
895365001200-ii.cuw is a Toyota or Lexus firmware catalog identifier tentatively associated with the brake and stability-control electronics. Toyota part numbers in the 89536 family are used for skid-control components, but the complete identifier alone does not establish the exact module, vehicle application, or software function.
Possible control-system role
A skid-control ECU monitors wheel-speed and other vehicle signals to manage functions such as anti-lock braking and, where equipped, traction and vehicle stability control. These systems help regulate braking or engine output when the vehicle detects wheel slip or a loss of stability. That describes the controller family, not a confirmed change made by this firmware revision.
The -ii.cuw ending is part of the catalog filename. It does not, by itself, identify a stock or modified variant or establish compatibility with a particular vehicle.
