How to activate remote start and change VIN number in GM's instrument cluster BMC

In order to activate remote start on GM vehicles you need:

1. Find VIN car("new VIN"), which have remote start options (PRO code BTV).

2. Update firmware for BCM from SPS with "new VIN".

3. Change VIN in BCM from "new VIN" to your original VIN in order to odometer shows correct data. For this you need cheap CH341A EEPROM tool like this.


USB BIOS EEPROM SPI FLASH Programmer CH341A 24 25 series

 

The following video show you how to setup the chip reader and program the chip.

It would probably be best to first make a backup of the chip in case anything goes wrong. Then you can view the contents of the chip. In the software, the left side of the screen shows the actual program, which is displayed in Hexadecimal numbers. The right side shows a translation in plain text.

On the right side, look for a string of numbers that look like a VIN. It is usually only a few lines down from the top. It is always missing the first number of the VIN. Replace it with your VIN (minus the first number) by simply highlighting each letter on the right side and typing in your VIN. Then program back the chip and you’re done.

Добрый день.
Никто не разобрался какие калибровки отвечают за автозапуск? Поменял 2. Система 9. Управление гидропередачей 20. Регулировка вентиляции и кондиционирования у меня машина перестала заводиться, хотя ошибок не было. Менял отдельно 9. Управление силовой передачей, но запуск не появился. Заменить все калибровки не получится, как я писал выше, автомобили-доноры не имеют точной конфигурации систем.

Good afternoon. Did you manage to remote start opel astra j?

you need to collect your DPS archive for the ECU and BCM and flash the car.

In the BCM it is necessary to change calibration 5, in the ECU I don’t know.

Hello Guys for Insignia i can activate Remote Start Finally. On Petrol you have to Change 1 DID

Hello.
When you say 1 DID, do you mean 1 calibration DPS or 1 DID in XML, for example DID0027?

1 DID for example DID0027?

Hi all.
Help me out guys.
I found over 50 VIN numbers for Buick Enroce that came with BTV from the factory.
I checked all these numbers manually and wrote down the calibration numbers.

I made myself 12 different DPS archives, all of them successfully loaded into my car, but I still did not have a remote start menu in my radio.

 

The radio just now has a menu for turning on heated seats with remote start, but there is no remote start itself.

 

What am I doing wrong?
