Back at it again, with no luck.


I got the repaired module back, and the bypass as well, hooked everything up, cleared the codes, all of the errors cleared EXCEPT the passenger occupancy error, even the old internal control fault cleared! But then when i disconnected the passenger bypass and reprogrammed it to not have the seat occupancy,which said it wrote to the unit fine, i scanned again, and the internal control fault showed right back up when i went to scan for errors again, along with the same passenger occupancy error! So, i've narrowed it down to the little black SBE box that may be causing my issue for the occupancy sensor. I unplugged it completely, and rescanned, and now it showing 4 SBE errors, but they're all yellow, and not present!


But now im back at square one, the unit has F0 internal control fault again, and the errors will not clear. How can these brick THAT easy?!?! When i did the first clear, I did not start the vehicle fully, i had only turned it to position 2, and the codes cleared fine, but after leaving it on for several minutes trying to figure out why it still showed the occupancy error even with the bypass plugged in, my batter voltage dropped to around 11.6V. Can anything under 12V cause these to just brick? I do have the second module that i can ship off and have them clear again, and try to do this again while the vehicle is started, and make sure that its above 12V when i clear everything. Quite frustrating this is!
