Procedures
4B.3.3 L/R ECU B FAIL
L/R ECU B FAIL
* Left/Right engine ECU B has detected a failure
or
* is being tested during ECU test procedure before
take-off check.
Depending on the type of failure, the ECU failure cautions are either ‘non latched', i.e.
the caution message disappears after the cause of the caution is no longer present or
‘latched', i.e. the caution massage remains until cleared through maintenance action.
A ‘non-latched' caution clears itself only on the active ECU. ‘Non latched' caution
messages can be cleared on the passive ECU by switching to that ECU with the voter
switch.
