GM Acdelco used to charge none commercial customers $40 to access its SPS service any VIN. They changed it to $40 per VIN, then to $45 per VIN. It's now very costly if you only want to get some calibration files for programming and experiments. With this trick, you can gather all the calibration files you need for any VIN without taking up a VIN slot in your ACdelco account.
Doesn't GM realise that making things very expensive fuels people's ambition to find a workaround?🙂 
The trick is pretty simple. All you have to do is unplug the OBD diagnostic interface or switch off the CANBUS data line before Techline SPS programs the module, then use Windows task manager to kill the Techline Connect application, then redo the process for the other modules or a different VIN. This same trick can also be used for Type4 files.
 
The method I use to get files is. I have a bench setup for 2 and 5-byte systems consisting of an ECM and a BCM. I can use this bench setup to get files for various GM vehicle models.
Another handy tool is the GoDiag GT100 OBD 2 break-out box. This device makes it easy to connect modules on the bench. It also has a switch that, instead of pulling out the diagnostic interface, you can flip a switch on the GoDiag GT100. You can also purchase extra GT100 DB25 connectors from the GoDiag Aliexpress shop, which is excellent for connecting various modules without unplugging them to use the one DB25 connector the GT100 includes.

VCAP, vehicle wide capture of module identification data. The VCAP interpreter tool can be used to view information for all the modules installed in a GM vehicle. For example, check the module's canbus data line, ECU name, ECU ID, part numbers, VIN, Mec state, security seed, and the mileage that's stored in the IPC, ECM and BCM. The vehicle's mileage records are stored in IPC, ECM and BCM. You can also view other information like vehicle specs, the vehicle's RPO codes etc.
Included is the VCAP Typ4 app, which can be used to read the VCAP from the vehicle.

As they say, never give up. Whenever you face a brick wall, frustrated with nowhere to turn, eat some food, get some rest, and then tread on some more. The ECM VIN and PIN change via DPS have had me baffled for some time. Today had another go at it, and after drinking seven cans of Redbull and a lot of thinking, I solved the puzzle/hack.
Changing the VIN and PIN in a used secondhand GM ECM module is very important for those who want to recycle GM ECM modules. With this solution, you can achieve just that. At this moment, it only works for 2-Byte seed ECM modules. I have some 5-Byte ECM coming from the USA. Hopefully, I'll figure out the 5-Byte ECM VIN change with DPS when they arrive.
 
Watch the video below to see how quickly you can change the VIN in the ECM.

Recently my Insignia developed a squealing noise coming from the engine bay. The noise was coming from the camshaft seal and PCV valve located in the engine rocker cover. Due to the faulty PCV valve, the car was building up a lot of vacuum in the engine, sucking air through the camshaft seal. From reading on the web, this is a known GM fault that will happen over time in the 1.6 SIDI  A16XHT engine. In the USA, GM had a service bulletin regarding this issue on the Buick Cascada, which uses the same 1.6 SIDI engine as some Astra and Insignia here in Europe. In the USA, GM replaced the rocker cover free of charge. However, folks in Europe have to pay for the replacement.
In the video below, I demonstrate the issue and the replacement proces

GM VIN Number To PIN Code/CarPass Service
This service is for generating the 4-digit security PIN code/Car Pass from the VIN for all General Motors brands of vehicles.
This is a great option for folks who wants to generate a few PIN CODE and is on a budget.
After purchasing, I strive to send you a private message with the PIN code between 30 minutes to a few hours, depending on your purchasing time and where I am located at the given time.
 
Purposes for this service 
You can use this service if you bought a used vehicle that did not come with the security PIN code credentials, and you need to program a module that requires the PIN code to program it via the GM online SPS service, for example, the ECM, BCM, IPC, and EBCM. You can use this service to find out the PIN code in a used GM module when needing to change the pin code that's stored in the used module.  
 
 
Alternative
An alternative method for generating the PIN CODE from VIN, is to use this Emulator tool, which is great for folks who wants to generate unlimited PIN CODES.
 

This DPS file can change the PIN CODE in most GM Global-A 2 bytes IPC modules.
 
Without a pin code change in a used IPC, BCM, ECM, you won’t be able to program those modules via SPS using the vehicle’s original PIN. You would need to know the PIN for the vehicle that the used module came from. 
 
Important
In order to change the PIN code in a used GM module, you will need to know the PIN code that’s already programmed/stored in that module. Without knowing that PIN code, you will not be able to change the PIN code in the modules using DPS. You can use DPS to read the modules VIN, then find a source that can convert the VIN into the PIN code.
You have to wait 12 minutes for the PIN code programming procedure to be completed by DPS.

Global Diagnostic System 2 aka GDS2 
GDS2 is GM's motor vehicle diagnostic software used by auto mechanics to perform diagnostics, including reading fault codes, resetting electronic modules configurations and various other configurations.
In order to have access to GDS2, one has to subscribe 
In this tutorial, I'll demonstrate how to pay once then have GDS2 access for eternity.
GDS2 uses two security measures, a hardware ID file and a system licence file. This tutorial circumvents the system licence file. That's why one needs to purchase a GM subscription in order to obtain the hardware ID file.
 
Step 1
Purchase a GDS2 subscription for the shortest/cheapest length
For USA cars, use ACDelco.
For European use ServiceBox
 
Step 2
Install and run GDS2 on all the PC you intend to use the GDS diagnostic software.
 
Step 3
Navigate to C:\ProgramData\GM\TIS2WebProxy\.dls\.lreg 
From that folder, delete the licence file that's there and replace it with the attached infiniteLease.dat file.
The infiniteLease.dat file also works with the new Techline GDS2 
 
Step 4 
Restart the GDS2 application. The Days remaining until lease expires should change to infinite.

Officially when you purchase the HMI navigation map update from GM, GM dispatches the map update on a USB stick drive, which is locked to the VIN number submitted when purchasing the map update.
This added map update security makes it impossible to use that map update USB stick to update the HMI module in cars other than the one you purchased the map update for.

In order to overcome the map update security issue and to be able to use map update USB sticks on other cars, one has to perform a few tricks.
As mention, the HMI module map update USB stick is locked to the car's VIN number it was purchased for.
The trick
Step 1
Temporary change the VIN number in the car's BCM module to the VIN number of the map update USB stick.
 
Step 2
Temporary change the VIN number in the car's HMI and radio module to the VIN number of the map update USB stick.
 
Step3 
Extract the map update file onto a reputable USB stick drive.
 
Step 4
Place the map update USB stick into the car's USB port and let the car update the map.
 
Step 5 
After the car updates the map, do steps 1 and step 2 again, change the BCM, HMI, and radio module VIN numbers back to your car's original VIN number.

There are two known options for changing the BCM module's VIN number using GM DPS programming software.
Option 1
Use SPS to acquire the XML files for your car's BCM module then use the XML files method to change the BCM VIN number.

Option 2
Use GM DPS programming software and my custom BCM VIN change file to change the car's BCM VIN number.

This is a partial tutorial.
It's beneficial to read up on this other tutorial to familiarise yourself with GM's calibration files concept if you're new. 
 
 
I will demonstrate how to trick GM's online SPS into giving you the needed calibration files when the module is already updated to the latest calibration version, or has a different part number version for the car/VIN it was originally coded for.
Before you approach this method, you need to already have a set of calibration files for the editing process, maybe from a different car's Vin number, which is using the same specs module.
This method works best with GM's European marketed cars. With the marketed European cars, only one file needs to be edited to carry out the trick. More than likely, all the files in the calibration package will need to be edited with the American marketed cars( I could be wrong on this).

This file will activate the HMI 2.5 and Radio/SilverBox module to learn whatever VIN number that's stored in the BCM module.
One file which will relearn the VIN Number for both the Radio/SilverBox and HMI module.
Remove the Theft lock from both the Radio/SilverBox and HMI module.

This tutorial illustrates how to update your 2014 Insignia-A/Buick Regal 8-inches instrument cluster to the last firmware update. This update will gives better graphics and features, with minor differences compared to the later 2019 Insignia-B instrument cluster graphics. Before you attempt to upgrade the instrument cluster/IPC firmware you need to take into account 2 important things. You need to already have a Buildrecord.txt file with all your car’s RPO codes in the list. DTC error may pop up on your IPC screen and you will need to deactivate them manually by editing IPC’s XMLfile.xml file as explained in the other IPC tutorials.

How to manually change the VIN number in an 8-inches Insignia instrument cluster.

This tutorial shows how to change the VIN number and security pin number stored in the IPC EPROM chip.
Tools you will need
Soldering iron and solder. A hot air rework station or solder wick use for removing the EPROM chip. A chip programming device I use the GQ-4X Willem Programmer A hex editor I use Synalize Pro for Apple Mac  
The process is very straight forward.
Take apart the IPC and remove the circuit board. Remove the 8-pin soic EPROM chip. Place the EPROM chip in the chip programmer. Read the chip and save the chip's .bin file. Open the .bin file in a hex editor. Find the location of the VIN and four-digit PIN code. Change the VIN and PIN code to the ones from your car. Save the edited .bin file.  Use the chip programmer to write the edited .bin file onto the EPROM chip. Solder the EPROM chip back to the circuit board.  
After doing this, the car's mileage will display correctly on the IPC unit.
You will now be able to program the IPC unit via GM online SPS using your cars original four-digit pin code.
You will receive an IPC DTC error from GDS2, which states "Incorrect Immobilizer Identifier Received"
To eliminate this DTC error, you will need to use GM's online SPS immobilizer learn to delete your car's keys and relearn your car's keys.
There's a much faster method for changing the VIN number in the instrument cluster using GM DPS software.
However if you want to change the four-digit PIN code the cheep way, you will need to remove the EPROM chip to do it.
