2009 Mack GU713 with MP8 engine dying out randomly?

Recommended Posts

2009 Mack randomly shutting down. When it shuts down the ABS throws a code for no communication with ECM, ECM is getting voltage but not communicating. If you cycle the key a few times the ABS light goes away Wondering if anyone else has had this problem? I am thinking it is either an issue with the J1939 datalink or a problem with the VECU but I am unsure on how to test the VECU. Any help is greatly appreciated.
