– = not charging
1= low batteries
2 = normal
3 = safe edge
4 = keyswitch off
5 = chair arm up
6= seatbelt not clipped in (optional extra)
8 = emergency lower/raise switch delatched
9= fault
there are further diagnostics on the main ecu accessed by pressing buttons and reading led codes and referring to a manual to match the code to a fault. It is very specific and will point you directly to anything in the fault 9 group. The system is not analogue and runs on a kind of canbus type logis on an a and b circuit using pulses so be careful with multi meters as this can damage the ecu.
