Nox a/ communication/>Communication codes. Dealers will reprogram the ECM free of charge. A faulty connection or corroded ground typically causes Volvo electrical problems. A loss of datalink communication could be the result of a potential problem with the wiring harness or connector pins with a short or open circuit but also a possible. No start of the vehicle and no direct communications to the engine management system – ECU fault right? Or could it be something else?Let’s ask Tim…https://w. Is there any way to reset the ECUs or to be able to see them? Thanks. Engine ecu, brake ecu,light control module, vehicle ECU and codes shown are: Engine ecu Mid128 sid231 fmi9 Mid128 pid84 fmi2 Trans ecu (sometimes active sometimes inactive) Mid130 sid231 fmi2 Brake ECU Mid136 sid231 fmi6 Mid136 sid231 fmi6 Vehicle ECU Mid144 sid231 fmi2 Mid144 pid84 fmi2 Mid144 psid200 fmi9 Mid144 psid205 fmi9. Check for Communication Related U-Codes in Other ECUs. The MaxxForce 7 TMV (Thermal Management Valve) is on the Public data link. The TECU (A13B/A13E) sends the actual driveline retarder torque value (% of reference torque) to VECU (A17). Volvo D13 cant see ECUs after corrupted update on software. For computers to communicate they need Power, Ground and a good set of data link wires. (sub data link CAN2) communications from the ACM is missing.
