I'm looking for Honda-specific training material, the sort that factory techs would have (or have had) access to. These would describe in great detail the exact function of Honda's engine management systems.
I have many OEM Honda service manuals, but their description and explanation of engine management is sketchy at best, boiling down to a very basic description plus flowchart troubleshooting.
This is an example of what I'm looking for: The poster quotes verbatim from a Honda OBD training manual that gives the function of the Idle Air Control Valve, which is a highly important component in the Honda engine management scheme.
There are resources available through a couple of auction sites, and I've asked several sellers for the details of their wares. Only one has replied so far. This one says his manual is paper-based and is not OEM Honda, but is from an outfit called "Jendham". They're at
American Honda has a large amount of exactly what I want online, but ONLY for those with US billing addresses. I reside in Canada, so I'm SOL for that. And Honda Canada has no equivalent.
Any suggestions? Is "Jendham" worth buying?
