6.4L Powertrain Control/Emissions Diagnosis Service Manual (2008)

There is a running joke in the 6.0 section that I am the ORG Librarian. This post won't help that joke to go away, I suspect...

Previously I posted a scanned copy of the 6.0L PC/ED. For those unfamiliar with the PC/ED, I described it like this:

... Anyone who has one of these knows that it's the shiite. For those who do not, I'll describe it briefly.

You know that one time when your brother was really drunk and he told you A) there is a Brake Pressure Applied switch on your 6.0 and B) how to effectively troubleshoot it? That came from the PC/ED.

Remember that other time when your great uncle - on his death bed - told you how to do a KAM reset? That also... well... you get the idea.
...

Today, I stumbled across a copy of a PC/ED for the 6.4 (2008) in CHM format. I will attach that, but it isn't the most useful thing in the world. As such, I will be posting the relevant sections that I converted to PDF.

Here is a qualification statement with regard to this post:
  • I believe that this document to be of print and able to be posted without issue. If you are overly squeamish in a copyright sense, do not so much as cast your eyes in the direction of these documents.
  • The PC/ED is for the MY2008. Use your brain if your 6.4 is not a MY2008. In fact, use your brain, regardless.

Because the forum only allows (5) attachments per post, this will take a few posts to complete. Be patient. ...and - to keep things together - I'd prefer if posts from others could wait until the last of the Pinpoint Tests go up.

Attached you will find the 6.4L Powertrain Conrol/Emissions Diagnosis Service Manual (2008) in CHM format:

2008 PCED 6.4L Manual.chm

CHM is a specially coded Microsoft Windows Help File file format. Download it to a Windows PC and double-click. The Windows Help System should take over.

For those of you using other operating system (I use Ubuntu), you may or may not have luck opening this. I did not and had to open it in native Windows using VirtualBox.

Also attached are:

2008 64 PCED - Engine Control Components.pdf
2008 64 PCED - Fuel System.pdf
2008 64 PCED - Powertrain Control Hardware.pdf
2008 64 PCED - Powertrain Control Software.pdf

___________________________________________________________
Edited to add...

Well, this sucks. The forum does not allow the attachment of CHM files. I will figure out a Plan B for that one.

Until then... the PDFs will have to do.

While we are at it... Electrical diagrams and a couple of odd stray documents that may be of interest.

That is it. Enjoy.

It turns out that the forum allows ZIP attachments. I did not know that. I guess that I never scrolled that far down the compatible files list.

...so here is the PC/ED CHM file zipped:

2008 PCED 6.4L Manual.chm.zip

It's cool to be able to use the PC/ED that way, if it works.

Thanks for the thanks. Given that there was absolutely no response to this thread after I posted it, I figured that the 6.4 crowd was all wallet and no wrench. Glad to help a fellow DIYer.

Wish I would have seen this 2 months ago... Made the thread slightly more accessible/find-able for people :thumb:

Thanks for stickifying it, @CrazyS0b . That'll help visibility immensely, yes!

I think PC/EDs are way helpful. Even though I don't have a 6.4, when I saw it, I couldn't pass up sharing.

Hi djmaguire, I tried to download the service manual you posted and i cant get it to download. It keeps sending me to windows help. Is there a trick or is the file no longer any good? Thank you for all the help. Any help with figuring out how to use the file would be greatly appreciated.

Thanks again!!

Sorry for the huge delay. I only just saw this.

I assume that you are referring to the ZIP file. I just downloaded it to my phone and it worked fine. You might try a different device or install WinZip first.

I'm a newbie, got a 2008 F350 Dually, four-door, w/6.4, and don't know anything about diesel's other than I love the truck!!! I've built cars, hot rods, and trucks all my life (64 yrs old) engines, transmissions, rear ends, paint, bodywork...the whole nine-yards and from the bare chassis up...but I know ABSOLUTELY nothing about diesel's and admit I'm a real dummy about them. I think you're really an incredible dude for sharing all this info. on-line.

I'm having some "power under load" problems (just loses all pedal response) I've noticed as well as a really loud "roaring" that something under the hood is making (sometimes/most of the time) while just driving along, so loud it's hard to talk...had one guy (said he was a diesel mechanic) say it was just the fans...if so, man they get really loud. My old 2001 F350 w7.3 never sounded this way. I hope some of this info will help me out.

I actually own a printing company so it's easy for me to print out!! Again, THANKS, your the best for doing this!!
