9.1.6
EECU Replacement
When replacing an EECU the stored IQA codes have to be downloaded from the “old” EECU
before removing it from the aircraft. It is recommended to perform this download earlier, be-
fore any problems arise and to save this downloaded IQA data file as described in chapter
“9.1.3 Saving IQA Codes” for archiving and documentation purposes.
Forgetting this step before installing the new EECU will result in additional work for the me-
chanic. In order to gain access to the injectors to be able to read or scan the IQA codes di-
rectly from the installed injectors, the turbo charger and the injector cover of the engine has
to be removed and reinstalled (see “Maintenance Manual AE 300”, document number
E4.08.04).
After installing the new EECU, the following steps have to be performed to write the IQA
codes saved from the previous EECU into the newly installed EECU:
1) Enter “Qualified Maintenance” mode
2) Select “IQA” tab
3) Click on Read ALL Cylinders button
-
A brand new, initialized EECU has to show the IQA code “AAAAAE” . This IQA code indi-
cates an adjustment values of “0” to the EECU including a correct checksum.
○
If the new EECU shows a “real” IQA code, chances are, the EECU has been initial-
ized with the IQA codes on file at Austro Engine for this engine serial number.
○
If the new EECU shows a “not set” in the IQA code fields, the EECU has to be initial-
ized by Austro Engine before it can be used on an engine.
