Whoa! You changed one of the digits on the checksum. That gets automatically calculated by FORScan. By changing it, you had to have changed one of the earlier, primary bits in the string.. This really isn’t good practice, What primary bit was affected by changing the checksum?

It was changed to 4x1x-xxxx-xxxx. I backed it out. So it was the process of backing out the change that fixed it. Good to know.

I’m not completely following, but I’m glad it worked out.

For mine I had to go 5684-008D because I enabled the climate auto seats functionality. Power flow is now back for me as well. Not sure about the camera in motion message being fixed about features being disabled though. Will need to test.

I’m just about sure your issues is the gateway config being goofed.

Anyone else with a ‘21 job 1 power boost notice their “Power Flow” screen is now gone? Was it replaced by Alexa or was it removed when I added the HVAC temps or enabled the unreal engine?

Amazon Alexa should be under settings, while PowerFlow is under Features. So that shouldn't be the explanation.

And here's Alexa with Unreal Engine rendering. (my goodness the rendering is deep)

So I don't know what would be the reason Power Flow would be missing. (not missing on my Powerboost, but not a 2021 either)

So nothing I did as that module was updated by Ford and their OTA updates. I only touched the APIM today.

So you guys know if I say 4 that is what enables that particular thing. So you would add it to what you currently have.

So if you have an 8 and add a 4 it would be C

If you want a specific change for your vin let me know. In situations where there are already values existing I can help you get it right

You’re correct, but I had enabled the HVAC temps on the top bar and in doing so told the APIM it was not a HEV. I needed to go back and adjust in Forscan and all is well.

The OTA updated the software but failed to update the config this was an update that required a new config yours didn’t flip to the new config it needs to

Nope I did not assume that was your intention. Thanks for the clarification.

I would also recommend that people be careful with just adding 4. In this example if you have a PB HEV and changed the 8 to a C it would also tell the APIM it is a PHEV vehicle which is incorrect.

if you’re not sure reach out.

Thanks, I havent worked with Forscan much. I’m going to education myself before making any more changes.

Got it, and I suspect there is a problem with FDRS and the GWM config tool.

 

[Jesse-Infotainment]

Checksum auto calculates in Forscan makes it much easier. The last two digits of each line is the check sum.

1111 1111 1111

Let’s say it changed to

9711 1111 1197

Then you change it

9711 3111 11C7

The best thing is Forscan does the hard part for you.

I think so. I think ther w is an issue in fdrs this time. I’ll look for a previous version when I get home.

If you have the previous version try to install it maybe .

I do have 32.5.4, 32.5.7 and 33.5.1 I could try. Will let you know.
