Siemens 5WY SIMK31 (Chery QQ cars)

Attention! All programming modes must be performed with the control unit, which is translated into programming mode exception composes "Link" mode, which game is intended for the translation unit of the diagnostic mode in reprogramming mode.

File Size firmware FLASH memory Siemens 5WY-SIMK31 (Chery QQ cars) - 512 kB (524288 bytes).

The loader supports reading / writing FLASH Memory ECU Siemens 5WY SIMK31 only in "on the table" when the computer is in the reprogramming mode (or so-called "bot mode").

Attention! It should be noted that despite its similarity with Siemens 5WY SIMK41 blocks, SIMK43 the ECU has differences pin-on.

Below are photos backed ECU 5WY SIMK31 car Chery QQ, the vehicle ECU is located near the driver's left foot.

Attention! 

​The data control unit no EEPROM. The information which is usually stored in the EEPROM memory in the ECU Siemens 5WY SIMK31 stored directly in the FLASH memory. This means that the read firmware is specific to each computer.

To put the computer in the reprogramming mode, it is necessary to supply power to him to close the 104 concluded the C167 (24 foot chip AM29F400BB) processor in the housing through the resistor about 8-10Kom (easier to use the stylus, with clothespin crocodile). must be set to mode After power to the control unit (ignition-on mode on the table) "Connect". Once a connection to the computer can execute commands for reading-FLASH write computer memory.

Connecting to a computer terminal

1, 2 - GND

21 - main relay +12

22 - switchable + 12V (ignition emulation)

44, 63 - continuous power supply + 12V (battery)

77 - K-Line

We recommend that before making a chip tuning, to learn whether there is a possibility to change the car's ECU program. Many brands of cars are equipped with a control unit, in connection with which the firmware of these units is practically impossible to change
