After redundancy has been LOST, Control Modules attempt to re-establish
redundancy every 30 seconds. This operation is similar to the establish
redundancy request except no diagnostic is generated. The redundancy state
remains LOST for five unsuccessful attempts. After the fifth unsuccessful
attempt to re-establish redundancy, the redundancy status becomes
TERMINATED. If redundancy is re-established before the fifth attempt, the
REDUNDANCY AUTO-ESTABLISH AFTER x TRIES diagnostic message is
generated. Once the auto-establish mode is entered, it remains active even if a
manual Redundancy Request > Establish Redundancy request causes a
transition to the FAILED state. It can be stopped by selecting Redundancy
Request > Terminate Redundancy.
