Siemens MS43

Attention! All commands programming must be carried out with the computer, which is transferred to the reprogramming mode other than "Connect", which is used to transfer a block of the diagnostic mode in reprogramming mode.

File Size firmware FLASH Siemens MS43 - 512 kB (524288 bytes).

All operations on reprogramming - reading / writing FLASH Memory ECU Siemens MS43 only in "on the table" when the computer is in the programming mode (or so-called "bot mode").

With the help of a homemade probe with a clamp "crocodile"

104 CPU cycles jumper conclusion C167 aka pin 27 feet FLASH AM29F400BB memory to ground through a current limiting resistor to ground 8-10KOm order to supply to the computer power supply. As the weight you cann't use the bus for ECU PCB perimeter of the circuit board. After the file a voltage supply to the computer (simulation the ignition is switched on the table) must level.The click "Connect".After establish communication with the unit, you can read / write FLASH / EEPROM of the control unit.
