Interpreting Diagnosic Connector?

[jpg]

I'm trying to understand the circuitry in my M1010, and how to effectively detect and diagnose issues. I see from the wiring diagram that the diagnostic connector contains pins leading to lots of interesting points in the wiring harness.

For each useful pin in the connector, I'd like to understand what signal/voltage to expect there, what is the range of normal, and what it means if the value is high, low, or missing. Is this info documented somewhere, or must I figure it out myself? I've been searching the threads, TMs and stickies for a while, with no success.

If time and funding permit, I'm thinking I'd like to wire a toughbook to this connector, and display the values for diagnostic purposes. If this works well, I might mount the toughbook on the radio rack above the transfer case, and use it to display things like tach/temp/voltage on a "glass cockpit".

I'd appreciate any pointers to good info on this connector, as well as any pointers to a source where I could buy the connector that plugs into the diagnostic port.

Thanks,

TM 9-4910-571-12 and TM 9-4910-571-34 and TB 9-4910-555-35
Get these off of LOGSA and they may give you some ideas.

Hm.

I've never seen a ste-ice.

But parallel port and db-28 cable is a common method of controlling stepper motor drivers from CNC controller software like mach and linuxCNC.

Sounds like it would be doable, if you could figure out how the ste-ice works, exactly.

As a matter of fact, if you could get a tach value this way, you could theoretically use this for a cruise control VSS pulse generator.

Check the Manuals section under Misc for one of the ste/ice tms and another related doc.

Far out man now I know where to connect my Reverse Time Flux Capacitor. Thanks for the free tip. This is going to be a real groovy experience. Wowserville man I just saw hitting a Century in my M1009. Awesome sauce. Woodstock here I come Baby.

Cool! Glad you liked it, just remember to use the correct inverse flux cable
to connect to the modified diag connector. Let me know if you need the plans
for modifying the connector.

Yes, please send me any relevant plans. Any and all clues welcome.

Sorry for the mislead. My post was in reference to CUCVRUS's tongue in cheek
response to my previous post. Reread his post and it will clear things up.
His references are to the movie "Back to the future"

Diagram E-11 and E-12 in the appendix of TM 9-2320-289-34 has the pin outs for the diagnostic plug.

Although I do have an STE/ICE unit I have never use it. Looks like you can measure: alternator voltage, fuel pressure and RPM

Have they released the STE/ICE manual to the general public? I know it was restricted not too long ago.

Just checked and the above publication numbers are restricted

Thanks. I'd found those diagrams. Firefox pointed me to http://www.steelsoldiers.com/showthread.php?132329-Ste-ice-tm9-4910-571-12-amp-p, which talks about what to expect on those pins. There may be more in the misc TM section. I'm still digesting the above.

I'm with you. DaVinci, Galileo, Newton, Einstein, Stephen Hawking, and Dr. Emmett Brown -- great minds that brought our civilization to the point where we can struggle to keep the smoke inside the blue box in a CUCV. Pardon me while I go run a slave cable to the clock tower. Maybe that will solve my charging problem.

I still welcome any and all clues, including those from the future.
