we are working with the FCCU and when we active RCCU_1 (NCF_11) we don't see any action by FCCU. In our opinion this means control is active but no fault is present.
But when we active the RCCU_0 (NCF_10) we se action by FCCU.
We have not any notice about difference between RCCU_0 and RCCU_1!
Can someone suggest how investigate reason of reaction of FCCU when we active RCCU_0?
