Programming Modes Supported by Kess V3 Kess V3 supports various programming modes according to different scenarios and ECU/TCU types: 1. OBD Mode (On-Board Diagnostics) • How it Works: The device communicates with the ECU/TCU by connecting to the vehicle's standard OBD-II diagnostic socket. There is no need to disassemble the ECU. * Areas of Use: It is the most common and easiest method. It is usually used for standard read/write operations, Stage 1 chip tuning, fault code reading/deletion (in some cases). * Advantages: Fast, easy, no risk of ECU disassembly. * Disadvantages: Full access or writing may not be possible on some ECUs due to anti-tuning protections (TPROT). There may be situations where only virtual reading (Virtual Read - VR) can be performed. 2. Bench Mode (Service Mode/Bench Mode) • How it Works: The ECU/TCU is usually Decoupled from the vehicle (or sometimes on the vehicle without being disassembled) and connected directly to the connector pins of the ECU/TCU using a special cable or an interface unit such as a FlexBox. There is no need to open the ECU cover. * Areas of Use: Ideal for ECUs/TCUs that cannot be programmed via OBD or need to be fully backed up. Cloning, full read/write, overcoming some anti-tuning protections. * Advantages: more comprehensive access than OBD, the possibility of full backup, usually faster data transfer, the ECU cover is not opened. * Disadvantages: The ECU/TCU may need to be disassembled, requires special wiring diagrams and cables. 3. Boot Mode (Bootloader Mode/ Bootloader Mode) • How it Works: It is the method that provides the most in-depth access. The ECU/TCU is disassembled from the vehicle and usually opens the cover directly to certain points on the circuit board (PCB) (boot pin, CNF1 pin, password reading points, etc.) connection is established by soldering or by contacting with special needle probes (probes). Full read/write access is achieved by switching the microprocessor (MCU) to bootloader mode. * Uses: It is used to recover locked, damaged (for example, incorrectly installed software) ECUs/TCUs that cannot be programmed with OBD or Bench mode, perform full cloning, apply very detailed modifications, or access password protected ECUs. * Advantages: The most comprehensive access, the potential to recover locked or damaged units, access to all memory areas (Flash, EEPROM, in-MCU memory). * Disadvantages: It is the most complex and risky method. The cover of the ECU needs to be opened, requires soldering or precision probe connection skills. An incorrect operation can cause permanent damage to the ECU. It requires more technical knowledge and attention.
