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.

what about pin code change on hvac?

When I check on my car it states the HVAC doesn't store a PIN. Are you sure your HVAC store a pin?

If uses opcom (Fantomel versions), you can insert a security code.

I have 2 units of hvac module (13582900, 13505739), uses the same utility file 13505783 and have security code.

Tonighit i have been testing to change the pin, but sometimes changed and another sometimes no. im not sure why...

Hi, Im doing tests and i see this.

With opcom, when insert the security code and accept the code i have this response:

251   [8]  07 AE 7E 80 38 37 35 35                My code 8755
651   [8]  02 EE 7E E3 FE 03 FF FF                 >>>>>>>>>>>> 02 EE 7E means, code accepted

 

But if the code not acepted,

251   [8]  07 AE 7E 80 38 37 35 35            My code 8755
651   [8]  05 7F AE E3 FE 03 FF FF            >>>>>>>>>>>> 05 7F AE means, code not accepted

turning off on ignition, accepts the code again. OK

 

Using my DPS file, ALWAYS gets a 05 7F AE response when insert the code.

  can0       651   [8]  01 50 B0 99 FE 03 38 31
  can0       651   [8]  01 68 B0 99 FE 03 38 31
  can0       651   [8]  02 E2 00 99 FE 03 38 31
  can0       651   [8]  01 E5 00 99 FE 03 38 31
  can0       251   [8]  02 27 01 00 00 00 00 00
  can0       651   [8]  04 67 01 49 2B 03 38 31
  can0       251   [8]  04 27 02 B6 D4 00 00 00
  can0       651   [8]  02 67 02 49 2B 03 38 31
  can0       251   [8]  07 AE 7E 80 38 37 35 35
  can0       651   [8]  05 7F AE E3 04 06 38 31


I removed the security access, same result....

Any idea?

There is no seat heating in my vehicle, can we activate it by simply assembling the seat heating pads and updating the software without changing the unit?

Need a custom calibration on BCM and you just change a HVAC control panel.

so, does the seat have heating pads available, just panel change and BCM update needed?

Once you've done the wirings, basically yes.

If change VIN, It can not change PINCODE

Just relearn your keys and HVAC will accept new code

Not really. I had to use abrites to change security code to get keys programmed.

Insignia A have Removal Type 4, and works in, for example, Astra K HVAC module. I tried IT and works. reset the module.

Hello
If I had heated seats in my Astra K and I'm changing them to EGR, should I program the HVAC module or replace it?

@Arbe_gtc Hi, could you tell me what OPCOM commands you use to read PIN and VIN and change them in modules like HMI, IPC, and Silverbox? Thank you.
