How to bypass GM 24-digit body module BCM security verification code for 2021- new GM CAN FD models?
Autel CANNOT do the new GM immo system. the ONLY aftermarket tools that can do it are obdstar, xtool and autopropad.
Obdii365.com here provides top 4 tools to bypass new GM pin code.
1). Xtool tools
The $500 or less Xtool D7, D8, D9, D9 Pro can do CanFD, even 2023. (Stand alone the D8 & D9 ) (with CanFD the D7). X100 PAD3, A80, A80 Pro will also do this.
D7 does this fine. The D7 didn’t have the CAN FD so you had to get a different cable and use Xtool CAN FD adapter.
There’s no provision to get the pin from General Motors. I’d get a Xtool programmer (I’ve used D7 and D8). The D8 is a bit easier to get going but I’d also consider a D7s as it says it has Can-Fd built in. I did 3 of these today with my D8. Check It out, there was a small issue but it ended up working fine.

2). OBDSTAR & CAN FD Adapter

V33.45 IMMO software adds Cadillac Escalade 2021-2022, Chevrolet Corvette 2021-2022, GMC Canyon 2020-2022 proximity (with CAN FD Adapter).
Example:
3). AutoPro PAD Basic and Full
Yes Basic, (despite what the CanFD tools sales website says) can do CANFD PROTOCOLS with the CANFD ADAPTER.
app basic with regular cord then canfd adaptor to Obd.
Must have good cellular/internet connection. We had trouble pulling the pin using mifi Internet boxed but works? fine on cellular hotspot (we all have iPhones with the “Maximum Compatibility” option selected).
I purchased the Xtool CanFD Adapter and together with the Xtool Auto ProPad Basic I was able to program a 2021 Cadillac CT5 today. Same Process as usual GM vehicles with the CanFD adapter.
4). SPS2
Can be done with sps2, no need code or nastf. Only subscription.
If you have a laptop and J2534 passthru device (MDI2, Autel Jbox, VXDIAG etc) you can do it from acdelcotds through Techline Connect.
For example:
Had one today, IM608 required 3rd party to calculate out code, Techline with the Autel JVCI and CAN FD adapter added key in 15 min including the 10 min wait, not including the 5 hour wait for Techline server to come back up. I swear these outages are intentional to deter aftermarket, I couldn’t imagine franchise dealers have these interruptions.
