Ideas for my ALP stuck in parking mode...

Well that narrowed it down pretty easily.

Unplugged "Head B" from "F2" and drove ~15 minutes.
No issues.
ALP fired up, instantly said "Warning: Sensor check failed" then went into "Defense Mode" 1:05 into it's bootup (including the 60 second boot time)
Worked flawlessly the entire ~15 minute ride

Turned everything off. Unplugged "Head A" from "F1" and plugged in "Head B" into "F2"
"Error 2" "Warning Sensor check failed"
Then it took ~1:40 to boot into "Defense Mode" and the second it did: "Error 2" - "Error 2" "K-Band" - "Error 2"
I got ~6 errors in 5 minutes of Driving


Stopped, and turned everything off

Unplugged "Head B" from "F2" and plugged "Head A" into "F2". (This was to make sure the "F2" port wasn't the issue)
Normal Start up sequence, and drove ~10minutes without a single issue.


Got back to my place, turned everything off and put "Head B" back into "F2"
Took 1:28(ish) to go into "Defense Mode" and 2 minutes later "Poliscan" alert.


So I now know it's either that head or that wire. Now I just need to find time to swap over the cable from "Head A" to "Head B" and try things. That might take some time


Thank you both for your input. Looks like I'll have to run with the 1-head for awhile until I have time to troubleshoot the exact cause.
