Until recently little was known about the programming of hybrid or micro hybrid plants used in the automotive industry.  It was a technology applied in Brazil mainly in vehicles of the brands Fiat and Chevrolet.  But they could also be seen in other automakers such as Peugeot, Citroen and Renault.  Hybrid plants are considered disposable in case of physical hardware problems because they do not have a printed circuit board like other vehicles’ modules.

Example of an open micro hybrid plant.

As can be seen in the image only what can be seen are microscopic components without protective encapsulation wrapped in an industrial gel, and only one or the other smd component without identification.  Virtually impossible to repair, because the change of components is not possible.

Finally hybrid centers are something that give even work, even in question of reprogramming because there is little material available about them, and in the case of a possible change of the plant because of a physical malfunction you will need to reset it to program the immobilizer or the vehicle will not come into operation.

That is the sw gm or FlashGM because with this tool pack you can reset and reprogram the immobilizer of micro hybrid power plants, besides being able to rewrite the number of chassis in the memory of the ECU and also download the internal software from them.

To be able to use sw gm you will need:

  • A computer running Windows Xp or higher,
  • An EOBD Interface Communication Cable (You can make your own see here).
  • The Galletto 1260 data transmission cable is also compatible with the GM SW/FlashGM tool and can be used.

With the FlashGM – GM SW tool you will be able to reset, edit the chassis, and pull the immobilizer password from the vehicle plants:

  • Astra
  • Vectra
  • Meriva
  • Zafira
  • Corsa
  • Classic
  • Montana
  • Celtic
  • Set up GM2 or Opel2R Immobilizer
  • And reset the Vectra and Astra auto-adaptive parameters

The tool interface is simple and easy to understand.
