Ive been seeing alot of EBR4 with UPS from construction that have 1 of 2 wires pulled for monitoring of UPS to X5 8/9 on option board 0 as per print.
When re-landed on terminal, Car goes OOS even with new batteries.
My question is, what is needed to correct this if at all?
Is just so Car wont go down when Batteries low/fail and not create a shutdown?


Thanks
