How can he be confident that his diagnosis is correct. You don't want to be firing the parts cannon at your car. Has he run a diagnostic check? If so what were the fault codes that made him believe another module was faulty?

maybe the instrument panel cluster itself is faulty causing the no communication code
 
here is the dtc showing IGPM. they pin point to the smart junction box faulty issue which as a whole need to change the IGPM

I presume they have checked the can bus wiring and signal?
nope…the smart junction box located near the obd2 connector so for now evertime its hot n triggered so just direct the AC to the feet direction to cool it down (for now)

No luck...still having issues. Next step is changing the ECU. as per agent they can't read the ECU (bec of mine is demo model) so now i'm not really sure what to expect anymore
 
did you fix it by any chance?
Latest our agent is ordering a new ECU (My ECU is locked n can't access as they said my car is a demo edition) so just going with the flow
 
ECU replaced n still no luck. They gonna install a temporary recorder (to record the DTC) and see how it goes. Where as new cluster already ordered
