SCAN TOOL TECHNIQUES
technology simply because that technology
does not exist on the car.
You'll want to become familiar with
how your tool indicates communication
with a module and whether or not there
are remaining codes. By simplifying this
process, the scan tool allows the technician
to focus on their expertise without needing
to worry about analyzing data and making
high-level calculations. Fast and efficient
diagnostic scans lead to efficient repairs.
In the case of the 2019 Chevrolet
Equinox, the only module that's coming
back with DTC codes is related to the lanekeeping
assist, informing the technician
that a recalibration will need to be done.
STEP 4 - DYNAMIC RECALIBRATION
A dynamic recalibration, or moving recalibration,
is performed on most domestic
vehicles and will require the technician to
follow manufacturer-specific directions
which can be found on their scan tool.
The first step in dynamic recalibration
is to put the vehicle into a
learn mode and take it for a test drive.
Depending on the manufacturer, the
scan tool will instruct the technician
to seek out specific road characteristics
including lane markings, guard rails, and
more. From there, the AI system in the
scan tool will take all of those inputs
into account and calibrate the lanekeeping
assist.
STEP 5 - THE POST-SCAN
Once the recalibration is complete and
all systems are working correctly, the
technician should run a post-scan of all
systems to ensure any issues with the
vehicle have been addressed. Not only
does this help the technician further
show their work, but it also gives them
and their customers peace of mind in
knowing the vehicle is back to 100 percent
of the OE specifications.
IN CONCLUSION
As the automotive industry continues to
evolve, the need for advanced diagnostic
scan tools becomes increasingly evident.
These tools can empower technicians to
confidently identify a vehicle's status
and resolve issues efficiently. The ability
to perform accurate and thorough
diagnostic scans will remain a cornerstone
of effective maintenance and
repair practices, ensuring both vehicle
safety and customer satisfaction in an
ever-changing automotive landscape.
