Gotta call on one of these and only have part of the print. Print is basically one page but been folded so many times it separated and parts of it missing. Does anyone know what 2I is�..2i indicator blinking on central processing unit. Car was taking a hall call but faults out just before the floor and right before roller cam actuates hall door lock ( now COP and car top no power at all -- we'll go back and should find that one pretty easy). But can anyone assist with what 2I is? It looks like 2i is blinking at fault stage (it is not the number 21). We would also see hard fault where it would trigger fault relay -- light on fault relay high and stays high until we cycle power.
