Lexus RX 400h 348A0100 899834815100 Firmware
A catalog reference for Lexus RX 400h firmware 348A0100 899834815100, identified with a 2007 3MZ-FE 4WD vehicle and an oil cooler label.
348A0100 899834815100 is a firmware catalog entry associated by its filename with a 2007 Lexus RX 400h, the 3MZ-FE engine and four-wheel drive. The label with oil culer appears to mean “with oil cooler,” but the filename does not establish which cooler system or control module the file belongs to.
What the oil cooler label indicates
An oil cooler transfers heat away from oil to help maintain an appropriate operating temperature. In a hybrid vehicle, cooling equipment can serve different components, so the label alone does not establish whether this file controls a cooler, identifies a vehicle fitted with one, or describes a modified software variant.
The complete catalog filename is Lexus_RX400h_2007_3MZ-FE_4WD with oil culer_348A0100 899834815100.bin. Neither a stock designation nor a specific modification is stated. The exact controller, software behavior and compatibility with another vehicle or module cannot be determined reliably from this identifier alone.
