Hello guys, Can anyone make calibrations for US to EU taillights conversion on these cars? I can provide the cars VIN if it is needed.

Hi, I’m looking for a GM engineer or specialist who can explain how the matrix headlights work on the XT6 or Escalade (so far, these are the only two gas-powered vehicles that have this option). My vehicle has upgraded headlights (3-lens, matrix), and when the vehicle starts, the LED zones turn on and off as part of a system test. However, the feature is disabled due to road regulations in the U.S. market, though it may be enabled in the Canadian and European markets. I compared the front camera calibrations (which appear to be the same as the Canadian version) and the K26 module calibrations, and I found that the difference is in a calibration related to Advanced Forwar…

Hi guys I’m facing an issue while testing the V-Series cluster theme on my vehicle, and I would like to ask for your guidance on how to resolve it. I own a 2022 Cadillac Escalade Sport, and I experimented by applying a V-Series VIN configuration to the digital cluster. The V-Series theme did successfully appear on the cluster, and visually everything looked correct. However, after applying this configuration, every time I start the vehicle I now receive the following message on the cluster: “Service Steering Column Lock” Based on my understanding, the steering column lock feature is exclusive to the Escalade V model, and my vehicle does not physically have this hardw…

Hi guys! Perhaps someone has already faced the task of replacing individual blocks in a GM Ultium battery? They operate at a frequency of 2.4 GHz like Bluetooth, but the MAC addresses are too large.

Someone have any idea how to be changed the VIN on th inverter of opel corsa electric 2020? I got a new inverter but there isn't any chance to change it, I try to read also the processor (Infineon tricore tc-275 ) but it sounds very hard found a solution. Thanks for your help.

Hey guys! I have an Opel Ampera MY12. The car's electric motor started to act weird, going forward then like hitting on breakes, then the elctric motor stopped. It went full crazy. The error codes: P0A46 - Drive motor 2 position sensor performance P1B04 - Drive motor 2 position sensor circuit tracking lost I swapped the whole motor to a working one, but since I dont't have the immo PIN to my car, I didn't swap the inverter panel containing the IC/microcontroller which counts the position of the motor. Both position sensors working fine, so I'm guessing the inverter panel is faulty. Do you guys have any tips what should I check/do before swapping the inverter panel? Any …

I build an archive for BCM module, same way I did other archives in the past via DPS software but when trying to program it, DPS says that the file is not a valid GMLAN archive. The archive is attached. ATS_BCM.zip

Hello Hackers Does someone have the SW Files for Chevy Bolt MY 19 PDC Controller UD7 K182 I have an Opel Ampera E I am an retired Engineer and I am struggling with programming the K182 PDC Controller. Since Opel divorced from GM 2018 everything went chaotic in Europe. I hope I don't have to explain more. My Ampera E was launched in Europe under very small volume exactly in the time frame when we were sold to PSA. Now the vin will not be recognized as an Opel Vin number under SPS. It is recognized as as Chevy Bolt 2019. The vin will be read and we can choose the K182 modul. Then the programming gets declined. Reason for this I have not a Chevy SPS license. I have a…

Hello guys! I have someone who wants me to activate some things on his Opel Insignia B. (W0VZS6GG4J1103656) • Remote engine start from factory key. • Fitting and programming Sport/Tour center console buttons. • And a front parking camera? I don't know if this is possible on HMI 2.5 without the "surround view module" installed. Is someone willing to provide me with some steps for this procedure? I have a VCX Nano, and did some work and retrofits/activations on my Astra K. but i don't know if VCX can reprogram the ECM to accept Remote start. (Heard from someone that it has some problems communicating with ECM prior to a update?) Any help received is good👐

Does anyone successfully disabled AFM programmatically (not via plugged devices to the OBD or keep vehicle in sport mode)? I have XT6 with V6 motor which feels annoying sometimes when going to V4 mode, especially at low speed, going 70, 80 is OK but city cruising sometimes is terrible. When in V6 mode all is smooth as supposed to be, no complaints.

Hallo, has anyone tried to Read the emmc on an IOB silverbox? Is it encrypet? Im interesting in knowing what software runs on the Radio. I think an Version of linux. Maybe there is an Posible to sideload Custom Maps since the Latest map is from 2019.

I have a 2023 Chevy Silverado that was submerged in water for 24 hours with the key on. I bought another 2023 that’s been severely wrecked what I’m wondering is what modules are able to be swapped with the Vin change and what’s gonna happen if I have to change all of them is it possible to change all modules? Of all the modules in this Truck, which ones report the event and where do they report the van too? I appreciate any help. Thank you.

Hello everyone, First of all, congratulations to this site for the quality of its presentation, its content, and all the contributors who keep it running. So, I bought a used, non-running 2014 Meriva B 1.7cdti Global A which had been quite heavily tampered with in the past. I changed the alternator, performed a relearn of the fuel pressure sensor with a Delphi, and the engine has been running correctly ever since. I reprogrammed two keys (the original Opel one and a generic one) with Opcom. I still have two problems. I have two permanent error codes: B3057-00 security code – not programmed B3925-00 Incorrect HVAC control module environment identifier received – malfu…

Hello every one, newbie her. I am a car enthusiast who likes challenges and likes to help friends around with their builds. With that said, I am new to the GM world. And by the way I hope this topic is not a double. The challenge I am actually facing is the greatest I've come across. A friend of mine had a loose negative battery pole, ending up frying the EBCM. After a proper diagnostic and the replacement of the module, only one fault code remains, something like "wrong immo data received". Car do not start because to my understanding, BCM sends the immo to the EBCM which send it the ECM, so car can start. After hours of browsing and internet research, I found this websi…

First of all,, sorry for all the newbie questions coming up (i got my hands on GM DPS 3 hours ago) 😆 So.. Im replacing an Airbag-Ecu on my 2010 NG Saab 9-5 (same architecture as Insignia A), a used unit with wrong VIN I got the Vin change file,with the help of Troy 🤩 Used Winrar, unpacked the file into DPSArch, programming went great..Vin is changed to the correct one.. No problem So.. whats left is to re-learn BCM and Immobilizer, to write/hardcode new Vin.. Again.. got the necessary file from Troy.. and well.. from here on.. I would REALLY like a tutorial... as i somehow cannot import/use that file within GM DPS.. Just says " cannot unpack file, Error" 😬 Yes.. I am awa…
