Features.
IMPORTANT POLICY UPDATE
Due to the complexity and increased number of logical controllers, it is necessary to
update the tool release policy. In the past, DiagnosticLink® was supported up to two
versions back. Starting with the release of DiagnosticLink® 8.19 in November 2023,
only one version back (e.g., DiagnosticLink® 8.18) will be supported until the next full
release. All earlier versions such as v8.15 through v8.17) will be obsoleted.
Please inform all service locations and fleet customers to plan in preparation for the
upcoming policy update and implementation. Failing to update to the latest or supported
version of DiagnosticLink® may result in the application becoming unusable and affect
vehicle uptime.
