DENSO's all-new Air
Conditioning Training seminar A/C Operation, Performance & Diagnostics provides a complete look at automotive air
conditioning, and is full of real world examples and case studies to help each
attendee apply the information back in the shop.
The ‘Why?’ Behind the
Laying out facts in sequence
is easier, but it isn't better.
Technical facts simply don’t directly translate into real world skills.
No single air conditioning component exists for its own sake, which is why it
is so hard to apply traditional component-based training back in the shop. This
seminar takes a completely different approach by layering the lessons, nesting
each new fact in the context of how it participates in the system:
all the components work together as a system.
categories of components required to make the complete system function.
variations of each component category that are used by various manufacturers.
Reinforcing the ideas
through actual diagnostic examples.
Using the Facts:
Back in the shop, the diagnosis of any air conditioning
fault follows the same general-to-specific path as the seminar. For this
purpose, we have included many high level tables where each diagnosis should
begin. These tables help each technician compare a symptom or code to the most
likely causes. The Denso diagnostic strategy then aids in deciding how to
eliminate the most possible causes with the least effort. Then all that is left
is to directly test the small number of remaining possible causes, making this
the most efficient way to service and diagnose any automotive air conditioning
