8.2.3.7.
E381: Timeout on activating CAN protocol on Generator board /
E382: HF not answering to CAN protocol
These two messages have the same meaning, that is a no answer to main
CPU (A5) from CAN messages, but their occurring is in different times.
E381 is generated during power on, while E382 is displayed after a
regular power on sequence.
In both cases, the error can be generated by a bad connection of the
CANBus or a fault on the local Generator CPU board, so the steps above
described for E380 are applied.
