SUBJECT:
Running Change to ACM Software for MY2020
SUMMARY
There is an upcoming running change (RC1) for ACM software that will be installed when OEMs
or distributors program with DiagnosticLink®. The hardware part number for the ACM module will
remain the same (A 000 446 97 54). OEMs are instructed to continue ordering the same ACM
hardware part number.
The differences between e7.60.2.0 and e7.61.1.0 are related to a number of software
improvements, most notably ATS sensor diagnostics.
