Headline & Summary

Restore the intelligent functionality of your luxury sedan’s rear cabin with this genuine OEM Rear RH Door Multiplex Network Computer. Sourced from a 2002 Lexus LS430 (UCF30), this ECU is a vital "node" in the vehicle's communication network, controlling the rear right power window, door lock, courtesy lighting, and sunshade functions (if equipped). Choosing a genuine Lexus door computer ensures that these systems respond instantly to driver and passenger commands without the communication lag or "dead" switches common with generic components.

Always buy OEM! The LS430 uses a sophisticated BEAN (Body Electronics Area Network) system. Genuine OEM door computers are programmed with specific handshake protocols required to talk to the Body ECU and Master Switch. Aftermarket modules often fail to support the "Auto-Up/Down" pinch protection or the global window opening feature found on the LS430. By installing an original Japan-made module, you ensure your vehicle’s electronics remain synchronized and fully functional.
