9.1.5
Scanning Injector IQA Codes
As explained in chapter “9.1.4 Overview” it is important to update the IQA code stored within
the EECU if an injector has to be replaced.
Manually entering the new IQA code has to be performed as described in chapter “9.1.4 En-
tering IQA Codes” on page 71. The typeface used to print the IQA code onto the injector
housing makes it hard to distinguish between letters like “1” and “I” or “8” and “B” etc. es-
pecially under adverse lighting conditions or if the injector has already been installed in its
place. Because of that, reading errors can happen and the erroneous IQA code (secured by
checksum and range check) will be refused by the ECU.
Therefore a 2-dimensional DataMatrix code has also been printed on the injector housing
which besides some other data contains the IQA code in machine readable form.
1) DataMatrix code
2) IQA Code
A special handheld scanner is available from Austro Engine, which has been programmed for
this situation (size, contrast and lighting) and will scan the DataMatrix field, extract the IQA
code from the data stream read and send the resulting 6 letters/numbers via USB to the PC
system running the AE300-Wizard.
-
The scanner connects to a USB port of the PC system and behaves like a keyboard con-
nected via USB (no device driver installation required)
-
Position the mouse cursor into the required IQA input field of the AE300-Wizard
-
The scanner has to be placed about 10 cm over the DataMatrix field to be scanned, it
emits a red laser aiming dot to help with positioning
-
Press the scan button and reposition the scanner until it lights up green and makes a
beeping sound while vibrating in your hand to indicate a successful scan.

See chapter “3.2.3 USB DataMatrix Scanner” on page 15 for ordering information
