Hi All - New to this forum so I apologize if this isn't the right category. It's kind of a tuning question. I was looking at the BCM settings and saw there was an option to enable the global window up/down feature. I enabled it, it didn't work, so I changed the PID back on the BCM. My truck won't start now! I get power, the different systems turn on with the key, but the engine won't crank. The brake feels different too. Any thoughts? I don't get ANY DTC's...

2019 XLT Sport. It's got 41,000 miles on it, so the warranty is out...

 

Is this a FORScan question?

Did you back up your as-built data?
Seems to me, if I am guessing, is that you used FORScan to enable some feature in the 'module' listing (not as-built). And you have since switched it back and now it's kaput?

If I am wrong, you'll need to fill in the blanks about what this 'tuner" is that you used. And how you stumbled across the settings and how you made changes.

I answered in a way only I can think to answer based on info provided. With that said, there are a thousand programmers on here that are smarter with those settings that I can pretend to be.

Also, Warranty is probably not even a consideration. Warranty work doesn't cover user computer hacking.

I'm sure it is something simple though. We (they) just need additional info to go by.

 

Thanks! Yes, you are correct about my current status. I didn't use FORScan, but to be more specific, I changed the values of DE15 and DE1A. Prior to the change I saved the original hex values and when the change didn't have the affect I hoped for, I simply re-wrote each PID back to the original value. Reading the values now show that it matches the original, so I'm not sure why the engine won't turn over.
