Default Because it doesn't exist for the public. There are no user replaceable parts, therefore

it will not list anything inside of the ecu...

Default So nobody has ever been able to even get a copy?

How about calling Hitachi and pulling it from the archive?

Default There is no need to... You are just going to see a bunch of resistors/transistors/capacitors and

other things like that... They are too small for anyone to solder without special tools... It won't make any sense to you unless you have a degree in electrical engineering... I have seen one for a Jetta and there is no useful info...

So what are you trying to accomplish with those diagrams? What are you replacing?

Default to start I would like to take a look at all the pin out information.

If you look at my other thread I am having trouble with a no-fire/no fuel condition. I have a bentley manual and have been thru most of the diagnostics. My vag-com will be arriving it about 2 days. I have been checking for shorts, terminal pushouts, etc. I am checking these things because I am at a loss as to where else to look. I would like to know what would cause both systems to shut down at once. Maybe they shut down if the system isn't perfect...but it would be nice to start eliminating things from the picture.
