CAN-timeout on message Electronic Engine Controller 2
â–¶ How to fix
Check the wiring and connectors on TMS (E5) and EMS (E44). Check if EMS (E44) has any DTCs and troubleshoot those. If any software upgrade is available for the EMS (E44) or the TMS (E5), proceed with the upgrade. If none of the above helps replace EMS (E44) and ultimately replace TMS (E5).
