the bsi line has only 2 components before it goes into AVILMA , R3400 and C3402. So, after removing these 2 components you still get Test mode just remove AVILMA(N2200) find the track that goes to the battery connector(bsi line) and check for impedance between BSI line and Gnd. If you find any the PCB was damaged by the liquid and the only way fix that is to put a few AMPS on that line and hope your impedance goes away.

Best of luck!
