So today we swapped ASIBNA boards between both cars, and the problem remained on CAR 2, so definitely not the board. even though the door lock circuit measure under 3 Ohms for 18 story building, and the fault is happening at multiple landings once or twice a day.
the KUET fault "extra info" hex was 0x00003601, which decoded gave me this:
E column (3) convered to binary is 0011:
> PHS = IN_FIN, PHNR_D = IN_FIN
F column (6) converted to binary is 0110:
> KUET FALSE, KUET1 TRUE, ENABLE UET TRUE.
GH column (01) converted to binary is 0000 0001:
> STATUS OF KUET AND KUET1 ARE DIFFERENT.
The only thing jumping out at me is why if this is a doorlock fault, would KUET and KUET1 be in different states... They are paralleled. that is also why I wanted to swap the boards incase the soldered on "Dold" relay was failing, hoping the issue would follow.
I will clean the heck out of every door lock, but I'm not convinced yet!!!
