CAN-timeout on MGUA3 End-2-End protected communication
â–¶ How to fix
Check if any Checksum fault codes are present. If yes, follow the actions for those fault codes. Check the wiring and connectors on TMS (E5) and the MGU (E82). Check if the MGU has any DTCs and troubleshoot those. If none of the above helps renew the MGU and then renew the TMS (E5).
