5: Automated System Test
TM
The Automated System Test™ does an automatic
test of the ECU being tested (primary system) and
any other ECUs (secondary systems) that can be
read, does an OBD-II test (if OBD-II), and then
displays a summary of the test results.
From the summary, you can view live data and
detailed test results, such as DTC descriptions and
related repair information, datastream snapshots,
freeze frame data, component test failure informa-
tion, oxygen sensor test results and system readi-
ness test results.
The Automated System Test includes functions from
other scan tool applications, such as Pathfinder,
Repair-Trac, InfoTech, and Fast Fixes (see
Software Descriptions
