No, not at all.
IHU is LIN (master), Flexray and MOST ECU. It does not communicate through CAN bus or ethernet.
MOST has its own protocol and data flow is only 1 way. Like a bunch of bulbs are connected in serial. The MOST cable has two fiber optic, one in and one out. That's why when a MOST ECU is disconnected from the network or faulty, a bridge must be used replacing the removed or faulty ECU. VOLVO has only two ECUs with MOST. IHU and AUD. In your case, you might have glitch in the system or the cable was out missing some messages like the diagnostic messages.
