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.

Hi, no I couldn't figure out how to activate it. Next summer I'll try some more.

Now Summer. It's time 🙂

I figured out the BCM part, but it seems the ECU calibrations files also needs to be modified for activating remote start, which I don't know yet.

Hi @JBL_1989, In Korea, there is any Chevrolet Cruze applying remote control to start the engine, isn't it?

Hi @Hero Tran, yes. it is. remote vehicle start disabled in factory but 3rd party modders are providing remote vehicle start on Chevrolet Cruze (J300) and all new cruze.

Good afternoon.
I've also been trying to activate remote start on my OPEL ASTRA J for a long time. The closest relative is the Buick Verano. When replacing the full BCM software, the AFL module K26 lights stop working. I'm trying to record the low beam calibration from my vin. But all the time I fail in programming on the last percent. Tell me what I'm doing wrong?

Dps programs to 99% that means the module was programmed fine. I don’t know why you got that error.

I get this error when I try to change the light calibration file.  When all files are native there are no errors and the block starts completely apart from the light.

No one will know the answers when swapping BCM calibration files. You have to try different files until you get it working.

@Sergey How about modify compatibility flag located at offset 0x00C, 0x00D?

A valid compatibility flag for your BCM is... (Calibration 06) 0x01, 0x18 (based on your BCM main program in archive file you provided)

I hope this helps you.

 

P. S.: I'm looking for BCM calibration file from VIN Holden Malibu 2014MY CDX - KL3GA69U9EB065370 (both &T3X / -T3X) anybody please help me to obtain calibration file 😄

Good afternoon.
No one figured out which calibrations are responsible for autorun? I changed 2. System 9. Power transmission control 20. HVAC adjustment my car stopped starting, although there were no errors. Changed separately 9. Power transmission control, but the launch did not appear. It will not be possible to replace all calibrations, as I wrote above, donor cars do not have the exact configuration of the systems.

Ich erhalte diesen Fehler, wenn ich versuche, die Lichtkalibrierungsdatei zu ändern. Wenn alle Dateien nativ sind, gibt es keine Fehler und der Block startet vollständig ohne Licht.

This is because your calibration does not match the OS you want to install.

What program are you using to modify the ecu? I'm trying to do the same to an 2015 Chevrolet Malibu LS. I had tried to do it through tds but it was asking for one very small file when I tried last year. I'm now delving into trying to get this enabled since it only needs an code to get it enabled with no extra parts. I had been away from all this programming for the past two years. I'm trying to play catch up now.

Any luck Sergey? Also wanted to activate it at Astra J.
