A method of communication between at least two automotive electronic control units, including two communication interfaces between the units enabling messages to be sent via one or the other of the interfaces, the units each including a microcontroller linked to the interfaces managing the sending and receiving of the messages according to a given priority level, transmission speed and recurrence, and including a diagnostic system for checking the functionality of the interfaces, a message scheduler, the method including: step 1: introducing a logic switch into each microcontroller, for selecting one or the other interface, step 2: checking that neither interface is defective, step 3: scheduling by the scheduler the sending of messages in succession via one or the other of the interfaces, step 4: selecting one or the other of the interfaces to send the messages scheduled by the message scheduler, step 5: sending the scheduled messages in succession by one or the other of the interfaces.
