PIN and VIN can also be changed in the IPC electronically using the GM DPS tool and my custom DPS PIN and VIN change files. See the service below.

How to manually change the EPROM PIN code and VIN in an 8-inch Insignia instrument cluster.
This tutorial shows how to change the VIN and security PIN stored in the IPC EPROM chip.

Tools you will need:

• Soldering iron and solder.

• A hot air rework station or solder wick for removing the EPROM chip.

• A chip programming device. I use the GQ-4X Willem Programmer

• A hex editor. I use Synalyze Pro for Apple Mac.

 

The process is very straightforward:

• 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 car's 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 and PIN in the instrument cluster using GM DPS software.

However, if you want to change the four-digit PIN code and VIN the cheap way, you will need to remove the EPROM chip to do it.

This process can also be used to change the VIN and PIN in the BCM module and the four-inch IPC EPROM chip.

Hi Troy, is possible to change pin code with GM DPS? 
 

or the pin code only can be change with reading and modify  eprom?

Not that I know of. Maybe it's possible with DPS but I don't know.

Hi I used clon UPA- USB V1.3 programmer with clip and don't need remove chip from the board on 8" ipc, to change pin and vin, and working on BCM too, maybe somebody needed

Wonder if this will work on USA Denali cluster? I have the VIN programmed but I'm still getting dashes for my mileage.  I need the PIN from my original cluster right? So the PCB board itself attaches to this tool?

Hi I'm not sure what eeprom you have on your cluster, you need to try, I'm from UK, I know is working on astra H and zabira B CIM module, without removing chip also

Hello Justin did you ever get you issue solved with vin change and lines on the odometer?

You driving 2016 insignia with VIN ending 32514.? Or its just donor Vin number?

Edited October 15, 20214 yr by Ernestas Dikinis

hi

TROY- yes reset mean online SPS- prepare to remove 

Ernestas Dikinis- no I'M not driving that car, my is from 2014

oryginal VIN on eeprom from 2016 insignia part no. 39066389 is on ebay to sell

Hi @troy. Can we change the number miles on eeprom BCM?

Hi, yes its possible to change the miles in BCM eprom chip dump file. 

You can use this app to do the mileage calculation.

It states PIN code is 1314.

Weird' I don't see the VIN Number.

 

 

Hey guys I removed my eeprom, edited the VIN number but there was no security code. I just assumed who ever had modded the IPC first time round may have deleted it out. After installing back into the car the IPC did not update the mileage and had reset back to stock losing all the themes and menus. Any ideas what I may have done wrong?

 

Cheers 👌

I don’t know what went wrong.

 

Thanks Troy, I forgot to say this is in a prefaclift. I will check the video still 👌

Hey @Troy

 

I think it maybe the hex editor I'm using which is why I don't see the security code. I opened this one you did and I cant see the 1314. 

 

Ive attached my bin file and screen shot of what I see if you don't mind looking.

Same here, I see the vin but no PIN.

it because is modified 8" for preface with different eeprom.

Hi everyone, another helpful read thanks for the sharing and brain sparkers Troy, I've been experimenting with this method on an Astra J cluster for a while, in principle it went well and GDS2 straight away showed the correct vin etc but the mileage continued to show dashes, I did see GDS2 showed Odometer lock status as 'active' whereas as on a working cluster that showed as 'inactive' . After hours of head scratching I've finally got it working and If its any help to anyone at all just shout and I'll get a screenshot uploaded of the byte that caused the headache (for me anyway). Can I ask though would the DPS tool to reset the vin have taken care of that odometer lock status active if it was present, or would the eeprom always have needed manually editing to clear it..? Thanks again..

Not always you need eeprom solution .

If its of any help to anyone, in my case the highlighted byte is what caused the mileage to still display dashes even after the VIN and PIN were successfully changed. 
01 = Odometer Lock Status 'Active'  -  dashes are displayed on the bench or in the car.
00 = Odometer Lock Status 'Inactive'  -  last known mileage is displayed on the bench and correct current mileage read from the BCM is displayed in the car.
