How you can explain that, there is voltage on pin 4 of PU103, but there is no voltage on pin 46 of KBC chip, regarding that this pins are connected together?
Repeat the following measurements:
Measure voltage to ground on pin 46 of KBC chip and pin 4 of PU103.
Measure resistance between pin 46 of KBC chip and pin 4 of PU103.
