I have a 17 Cadillac ats with RPO K69. It comes equipped with a TCCM to control the AWD transfercase on the vehicle. I purchased a spare for bench testing, part# 84160285. However I can't seem to communicate with it via DPS. Tried Address 1A to read info but nothing is displaying. Module has 2 connectors X1 pin 3 - run/crank ign 1 voltage 6 - accessory wakeup serial data 7-8 - high speed gmlan serial data 15-16 - high speed gmlan serial data X2 C - B+ D - grnd I have X1 3&6 hooked up to X2 B straight to B+ I tried hooking 7-8 and 15-16 to the DLC pins 6/14 but no matter what I do I keep getting "Error Occured During Request Info" with DPS reporting no subnet fo…

HI, If anyone needs a VIN from RPO codes, I can try to look it up. Just give me 3–7 RPO codes that must be present, and if needed, another 1–5 codes that must not be...

Hello people, I thought I'd drop a post on here to see if anyone here had an experience enabling the Climate menu on IOB radio, specifically for Astra K. I understand that Insignia-B with IOB and CJ2 usually have the climate menu enabled, although when I was testing insignia-B calibration onto Astra K, the display was somehow changed upside down, I didn't get much luck with changing varies calibration so far. This is what the climate menu looks like after insignia-B case was programmed in. I will probably have more time this weekend to investigate it further, for now I am wondering if anyone has attempted these climate menu. …

Hello. How do I calculate checksums for the sixth calibration in the ECM module? I know that the checksum is located in the first two bytes and in bytes 32 and 33. I used the Troy method and GM Checksum Cal available on the website. Neither method helped.

Hello, Doing some research and found this site, I am totally new at this and have a quick question. I am currently working on a 2020 Camaro but have an engine and transmission from a 2019 SS, there is a difference in the Transmission and TCM. Question is it possible to flash the TCM as a 2019 then change the VIN to the current 2020 or does it even matter? Will the BCM and PCM even look at that VIN? Reason for the change is the 2020 uses a 10L80 MI12 and the 2019 uses a 10L80 MF6 transmission, SPS will not allow me to program the MF6 for 2020 so was thinking of programing it as a 2019 and changing the VIN. Also will this software make that change possible…

Hello, Does anyone know a way to Power up am radio from an Astra K or J on a Banch? I know i need to send over GLlan the Power Sequenz but does anyone know what exactly?

Hi guys, i have various firmwares from Harman 3X and extracting it, i found this. I think its the functions of all calibration for the harman radio. Are totally different to the HMI 2.5 The most of the files are XML files. the file CalSets.db can be opened on net: https://inloop.github.io/sqlite-viewer/ Someone know how working the calibrations in this radio? how to edit the calibrations? for example, to change the boot animation by the way, the info 3 system are based in Android.

Hello, I'm new to this forum I wanted to ask if anyone has already done a swap from the HMI 2.0 module to the HMI 2.5 module on an American car. I have a 2015 Corvette (US imported) which mounts an HMI 2.0 module but the navigator does not work (can't find the satellite). I've seen in other forums that many have upgraded from 2.0 to 2.5, but is it possible to make it work with European maps installing the SW for the European model? Does the hmi 2.5 have the same hw for all models? For example, can I buy any hmi 2.5 and then program it with the correct sw or do I have to look for a compatible model for the Corvette? Thanks for any reply

Hi - I wonder whether anyone could generate/supply a cal file for the above. Its a Delphi E78 module. VIN: WOLDE88HB037165 Thanks!

Hello all i need some help i m totally noob on GM car how can i desactivation front short range radar the owner dont want fix it and just remove the error on the dash

I'm working on a K26 headlight module. Initially, the SPS2 software showed that these calibrations were on my vehicle: Current      →  Selected 84729301      →  84696811 84729299      →  84729299 Unrecognized cal.  →  849768037 But SPS2 could not program it. So I built a DPS archive based on the VIN and successfully programmed these calibrations: 84696811, 84729299, and 849768037. After programming, I'm getting headlight errors. I checked the DTC code and it says: "calibrations not programmed." I went back to SPS, and now what I see on the programmed ECU is this: 84696811 Unrecognized calibration 849768037 When retrieving calibrations for the VIN, I had to provide th…

Hi, I was trying to change the language on my A11 radio module. So I grab calibrations from my vehicle and EU model and replace only the language cal file, the other files remains unchanged. Programming succeeded, I can see Russian language on IPC but radio, navi and whole CUE does not work. CUE says this: "Perform calibrations. You must calibrate one or more devices before using the system. Could you advise what other devices I must re-calibrate to get this working? Many thanks!

hello , can I swap Global B amplifier with used one without need to reprogram or vin change ?

Hello. I need Pin outputs of GM Harman INFO3, how can I find them?

Hello everyone, I’m new here and far from being a car electronics expert. I recently bought a 2016 Chevrolet Silverado that came with the factory HMI 2.0 system. Since I wanted to have Android Auto, I purchased an HMI 2.5 unit and installed it in the truck. However, the screen stays completely black — no display, no boot. Now I’ve read that the new unit must be reprogrammed using the vehicle’s VIN in order to work properly. Would any of you be able to point me in the right direction on how to do this, or how to get it done (software, compatible module, tools, or service)? Thanks in advance for your guidance! 😄

Hello, i have the problem when i will load some ecus with PIN 1 33.3kbaud then he don't load it and after there is no os sw on the ecu. A Friend means the vxdiag load too fast. What can i do for the problem? Many thanks

Changing the VIN in a used ECC-HVAC Electronic Climate Control module is vital for folks who wants to recycle used secondhand GM electronic vehicle modules. Using this custom DPS file you can achieve that. Watch the video to see the process https://cameraloops.ru/uploads/videos/ecc_hvac_vin_change.mp4 ECC-HVAC VIN change for most GM 2 byte seed modules.
