I've used Focccus in the past to enable/mod functions but was always uneasy with the software because odd things would happen occasionally. I decided to install and tryout Forscan and when I selected the central config a message popped up about loading a secondary bootloader into the PCM. I canceled at that point because it sounded serious.

Has anybody allowed Forscan to load the sbl and if so, did you let it download from the internet or did you get it elsewhere? I read some posts on the Forscan site about a collected pack of sbl's but was a little leery of this.

Does anyone know what the software is actually doing during this stage and has anyone been through this?

I think I need a little hand holding, not looking to brick my daily driver.

Thanks in advance,

Dan

Side not, once forscan gathered your vehicles info, there is a backup bottom, click it and save it just in case, and for good measure, never sever the connection when it is reading, and especially when it is writing, let it finish what it is doing or you very well may end up with a brick on wheels...

with my 2012, I've done all my BCM/IPC editing in Forscan because it is so much better than FoCCCus by a long shot. I use Forscan for everything and it has never borked my vehicle

When it comes to loading the secondary bootloader, this must be something specific for newer year models as Forscan automatically loads whatever is necessary on my 2012, and I did not have to download anything extra.

as long as you have the proper SBL for your year and model, there should be no problem. i don't know all the technical specifics of how the bootloader works but it does control some part of the security so using the wrong one will most likely just not pull the as-built data of your vehicle

You will need an extended license if you want to use anything in the central config editing tools though. it's free from the forscan site and takes maybe an hour of wait time to get.

Hmm.... It downloaded a sbl for my 2012, it only does it once then reuses it. Maybe it is just mine. Pretty sure my BCM and/or IPM have been replaced (the IPM was not programmed when I got it)...

And on that note, be sure to also hit the 'write to backup' button. The BCM (main) is on the HS network which is what everything pulls config from, the IPM (backup) is on the MS network which is what provides config if the BCM can't be contacted.

(This may be false but it is how I understood it while dicking around trying to find out why the car was acting weird, the IPM (backup) wasn't programmed, it was loaded with nothing but hex F)

thanks for the info. I'll be trying this on my 2012 this weekend and I'll let you know how it goes. I already have the extended license so I should be able to try it out.

thanks

I'm able to access the central config ok but now I have further questions so hopefully someone with Forscan experience will have answers:

1. I installed the audio control switches in the steering wheel (airbag replacement) but the selection for steering wheel audio control is listed as not configured so I can't enable them, is there any way to enable this?
2. I installed a headlight switch assembly that includes the trunk release button but it doesn't do anything, is/can this be enabled with forscan?

Thanks in advance,

Dan

I was able to enable the audio control switches using Focccus since it populated the various settings for the central config. I'm not sure what you need to do with forscan so that settings appear for options that aren't in the cars as_built data. Oddly enough the audio controls that were enabled are the controls on the steering wheel and not the buttons on the airbag. Don't care as long as the functionality is there :)

The last task I'm hoping to enable is the trunk pop button in the headlight switch. I don't see any threads anywhere about this but I can't imagine I'm the only person looking to do this. Anyhow, if anyone has any insight on the trunk release function for a headlight switch assembly, I'd appreciate it.

Thanks

so here's the problem, apparently the trunk release button was never offered in 2012 so I am starting to think the code isn't in place in the BCM to turn this function on. If it is present then I think the only option is to find two identical 2013's, one with the trunk release and one without, and compare their as-built files to find the bit that turns the function on and try it.
