well if you do not provide a model and serial number of machine or model number of zapi controller it will be hard to help.
all zapi manuals i've looked at do not have Alarm 103 and we cannot know what node 16 is , that is assigned by truck mfg when they design truck.
having a service manual for this truck will be necessary to identify node 16 and have the correct model of zapi controller to get correct meaning of Alarm 103.
