| Item | Description | |------|-------------| | Device | Bosch KTS 540 – a compact, Windows‑based diagnostic and programming tool for a wide range of passenger‑car, light‑truck and commercial‑vehicle ECUs. | | Primary Use | Reading/clearing fault codes, live data streaming, ECU‑coding, flash‑programming, adaptation, and key‑programming. | | Software Suite | KTS 540 Software (also called “KTS‑540 V‑Suite”). The suite consists of the core KTS engine, the KTS‑GUI, and a set of M‑Modules (M‑Modules = “Manufacturer‑Modules”). | | M‑Module of interest | MHH‑Auto – the “M‑Module for Hyundai‑Hyundai (MHH)** auto‑programming. It handles the Auto‑Flash routine for Hyundai / Kia ECUs. | | Page 1 Verified | A verification step that confirms the first 256 bytes (Page 0) of the ECU flash image match the expected checksum before the Auto‑Flash routine begins. This protects against corrupted files and ensures the ECU will accept the new firmware. |
Why “Page 1”?
In Bosch terminology a page is a 256‑byte block of flash memory. Page 0 (the first block) is critical because it contains the bootloader / security keys. The MHH‑Auto module checks that the downloaded image and the ECU’s existing image have identical Page 0 before permitting an automatic flash. If they differ, the module aborts and flags “Page 1 Verified – FAIL” (the UI still calls it “Page 1” because the GUI is 1‑indexed). bosch kts 540 software mhh auto page 1 verified
