Genuine Toyota factory multiplex (MPX) body control ECU integrated fuse box assembly, manufactured in Japan by Denso. This complete electronic block handles the vehicle's interior cabin power routing and network communication, and comes bundled with its native, bracket-mounted Engine Stop & Start Smart Key computer module. If your vehicle is experiencing unpredictable cabin electrical drops, unresponsive central body modules, or start/stop ignition communication faults, replacing this matching assembly will restore total network integrity.

Fitment note: Please cross-reference your original unit configuration using factory part numbers 89221-52500 and 89260-52150. Natively engineered for the second-generation Toyota Sienta platform (XP170 models).
