BB 2019 ISB got the 3 codes for the header, TS and found no issues , R&r header still active
took the new part to sister unit with no issues plugged in and the 3 codes come active so its not the bus
2nd new header 10056545 from Gtech same issue as above again on both units
anyone got these and they were bad
good one shows 520ohms internal resistance on data link
the 3 bad ones(original and 2 new) show internally 140-238 ohms
just a heads up in case others come across this

part# 10056545 is a complete unit got part# 10071998, and installed in the original and no cel on unit so either complete units are not for this unit or something is bad internally
