9 ES891.x ECU and Bus Interface Module
ES891.1 and ES891.2 are named in this document ES891.x. Only if there are differ
-
ences, then they are named ES891.1 or ES891.2.
The only difference between the ES891.1 and ES891.2 is regarding the CAN-func-
tionality. See chapter “CAN Interface (CAN)” on page 160..
