Micropod 2 clone only reads PCM

Sorry mak...didn't see your other question "what is this program"
Apparently these micropods run linux as the os. There is a built in web based manager that exposes some os interfaces. I found a page on some of the web addresses on this site . The index page of the webconfig is where I saw the "vehicle connected" status message. Figured it couldn't be too burned up if the thing was still booting and I didn't see any kind of failures in the boot logs....

Many thanks @rdeyoe!
unfortunately what is written in that page is, for me, like arabic language… 😂
I am a basic level pc user, so I know how to connect the Micropod, run it and run DRB3, that’s all 😂

But I will show that page to a friend of mine, probably he will find it useful.
Thanks for sharing!

I am happy to see that you got the Micropod run on all units, …now I would like to help @Delta0, I am sure his Micropod works…

@Delta0,
why dont’t you share in this thread your problems in running the Micropod, I am sure we can help you and you don’t need to send it back.

I have a my 02 and everything works and I can read every unit; a friend of mine with a my 04 was able to read everything.

I was right about the micro-short, you are lucky that erasing it the Micropod works again; I would try reconnecting that pin, I think that with that fix the Micropod will read everything.

@Delta0 ,
If we were close, I would try to run your Micropod…., in my opinion you only have a software installation issue

Hi guys! I've been on business trip, and left my micropod in a trunk. It took time to get back and make a photo. Glad that @rdeyoe solved his issue and I hope that I'll solve mine with your help. I hate to ask dummy questions but without any data sheets of board and chip (I haven't find anything on 290 3R XB) my questions will sound like kind of stupid.

Which male pin of Micropod socket that is referenced to ground? The one that is a female opponent pin 5 on OBD socket?

Is it a correct point of soldering that is shown on a corresponding picture?

Thanks in advance.

Yes zavy, that looks to be the correct pin. The ground plane doesn't quite reach that pin, so the need for the solder bridge. My error was bridging that small gap between the ground plane via and the U29 (28?) regulator trace.

Thank you so much @rdeyoe! I'll try my own later this week.

Bingo! Thanks to Mak_v8 and Delta0 for your help and suggestions. Mak nailed it with the micro short i didn't see. I've re-soldered the ground bridge back, triple checking any nearby components for shorts/bridges with magnifying glass, cell phone magnifier and stick pins on my meter. It's working now! I can read all the modules in my truck (I'm working on a 2001 dakota with a jeep TCM). I can see BCM, ABS, HVAC, TCM, PCM. I was just wanting to do a quick learn on the TCM, since i just rebuilt the transmission a month ago. I was able to get the DRB3 to put the TCM into quick learn and it did it's thing. Dealer wanted $125 to "try" it with their emulator. When he said that, I started my research. I gave $135 for the pod and I'll certainly be using it again to program another PCM i have for the truck (I'm running a 2009 4.7 in it with knock sensors and my 2001 PCM doesn't support them. I have a 2004 Jeep HO PCM with knock sensor support, but it's throwing a P601 code...perhaps because of VIN or bad flash). DRB3 is now reading all my switches/sensors/monitors and such.

Huge thanks to oh2WJ for his hard work and for sharing the fix with the community.

I'm glad you got it sorted out bud! I havent been able to find anyone local to help me apply the fix to my mircopod. Could you help me out If I pay for shipping?! Thanks

Well no luck with my mod. The SMD soldering worked out just great, but none of the modules, except the PCM can be accessed with the DRB III emulator. Bummer.

I notice the chip does have a little different of a marking on it.

Just replace that IC with a good old fashion, easily attainable LM2903 miniSO8 and it might be fixed after all.
Just test that that solder bridge at pin 4 is only connected to ground. Pin 1 is where the dimple is at the corner of the IC.
Note: I've seen a few different ic's in that location depending on which factory made the board.
Check the pictures in post #65 for reference.
Tip: Use lots of solder flux. Don't run the soldering iron too hot. Don't keep the soldering iron on the solder contacts and legs of the IC very long.
Also, have some solder wick for removal, and isopropyl alchohol and an old toothbrush handy to clean up your excess flux when done.

Good Luck

Hello! I have a Micropod 2 which I have modified and confirmed pin four of the 27 TI MAP is connected to the ODB III ground pin.

Image


In the emulator I can run a module scan and it finds all four modules.

Image


Looking at the wiring diagram for my 2006 Wrangler the airbag module is only on the PCI bus, so this means that this scan must be using PCI and not SCI.

However, when I try to access any module except for the PCM I get an error unable to ID the module.

Any thoughts, ideas or inspiration on what could be the issue?

Thanks, Andy

That's interesting about post 76, I'll have to try that scan. I want to access ABS module and cannot. I haven't done the mod or opened mine up yet, maybe tonight. See below:

2005 Liberty CRD

I am new to this forum and have been wanting to try this for a long time.

One clarification needed, I need to scrape that little VIA hole (had to look up this meaning lol, and I'm an electrical engineer! Power though...:D)..then solder the pin over to it? Scrape to expose the metal trace below it right?

I tried it all, using slightly different method from youtube guy frugal pepper. It all works, but appears to only connect to the PCM as stated here. I'll have to do more testing.

I think the same thing is happening to me as post #57, as it only seems to show PCM into when I connect to TCM, very strange behavior. It doesn't not connect but I think it's same issue as discussed in this forum. I cannot read ABS module so assuming it's related.

When I connect to TCM it just reads the PCM. Interesting. But I get real sensor values out PCM. So it's all working but not sure what's going on.

I also rented the controller technologies emulator thing for $2500, and they refund it when you return it. I will try this also to see how it differs. It if ends up working I"ll be tempted to bit the bullet and just keep the controller tech kit.

It runs on modern windows but I'm not sure how it all works, probably same software, different hardware though. And you can flash with it. That's too much cost for old jeep lol

So far it will not recognize the USB device they shipped, so pretty disappointing. And they don't answer phone calls on weekends.

I did measure mine, pin 4 of the 31T1 MAP measures open to pin 4, .550M to pin 5

I measured the little VIA hole thing to pin 5 and get a short, pin 4 is open. So the connection is to pin 5, signal ground that is needed. I'm not sure I can solder something this insane small but I can try lol. Whoever figured this all out is mad skilled!

Does anyone want to sell me their Micropod 2...

... that is confirmed working with PCM and TCU modules in DRB III on a Jeep WJ ? I can get other modules with WJDiag app.

I bought a Micropod 2 from amazon which did not work with the PCM and TCU modules and DRB III. So I did the solder ground trick and no luck.

I would rather spend the money on something that guarantee works with the Jeep WJ PCM and TCU, than risk more time and money on another experiment. Heck I would be happy to send my Micropod to someone, pay them to fix it and ship it back. Or have them buy one, test it and send it to me. I more interested in getting something working than the money (within reason, of course)

I guess the other option, does someone have a source for a Micropod 2 that works with the DRB III PCM /TCU on the jeep WJ? There are a number of varients of the Micropod 2 so I am just not sure what to buy. The sellers are often dubious, with false promises and returns that are not honoured. The language barrier often is an issue as well.

jagster936 - the key to SMD soldering is:

(1) a good USB scope,
(2) fine point soldering iron with temp control
(3) thin electronic flux solder (with lead)
(4) keep heat to an absolute minimum

This is the USB scope I bought. It is inexpensive, but works quite well for SMD work. The pictures from my post above are from this cheapy USB scope.
