I keep getting this:
Maybe my donator PCM is either dead or my connections are totally out of scheme... How can I tell that ignition is on tinkering with it on my workbench? Do I need to put +5v on some pin to awaking it?

Post a diagram of all of your connections. I wired up an OBDII connector to a PCM on my workbench and got it to work - just required the data bus connections (there are more than one) and 12V power. Andy
Thanks andya for looking into this- drives me nuts…
DLC = ODB2 connector.
DLC pin 2 (PCI) goes to C3 pin 30
DLC pins 4,5 (ground) goes to C1 pins 4,31,32
DLC pins 6,14 (SCI receive) goes to C3 pin 29
DLC pin 7 (SCI transmit) goes to C3 pin 27
DLC pin.9 (BMC flash enable) NC
DLC pin 16 (Fused B+) goes to C1 pin 22
So, what am I missing or got totally wrong?
We will have some sunny days in the weekend so I will connect this donor PCM to my Jeep to see what it says. I do believe that there is a problem with the cabling in the passanger door as it sounds strange when using the remote to lock the door. I often find that the door is still not locked when it should be. So I will disengage that module before testing anything else and take care of any malfunction in the door module later.

Right andya - I have described my connections in both text and hires picture - your turn to show your working setup.

I looked but I can't find my wiring diagram, all I have is the wiring harness I made. I only used connector C1 and I took the connections from the factory manual wiring diagrams. For communicating with the PCM all that is needed is the PCI bus. My PCM is a known working PCM. Andy
Video of me using the DRBIII emulator to wait for the engine to warm up, looking at the evap purge values, running an evap purge test and looking at the diagnostic trouble codes.

I connected battery, ground and PCI to skim and pcm. Made a scan with the DRB3 emulator for modules and it found Pcm and skim. But when I go into the engine diagnostics - it doesn’t find the engine controller.
Has this to be done with the pcm connected in the car?

Has anyone found a Micropod2 anywhere that works completely out of the box? Mine will only pull the ECU module info, thats about it.
Thank you for staying on top of this excellent walkthrough! Now I only need to upgrade my soldering skills... significantly.
So I got the soldering done and now i have access to all the modules that I've tried. The only issue I have is reading DTCs. It freezes up each time I try. Is this a known flaw?
Hello,
I purchased a micropod from Aliexpress and followed all you steps to install the DRB clone.
I manage to launch the software, the Micropod is recognised by the software, but I cannot connect to any module: always the screen: no Response from PCM ...
I tried with Ignition ON and also engine running.
Is there something I can check? A test mode?
I checked the continuity between the ground and pin of TI chip: they are connected.
The car is a 2000 XJ 4.0

AndyA, thank you very much for this writeup. This helped me solve the cam/crank misalignment issue I have been experiencing on my 06 TJ.
I used the UTM software on my intel-based MacBook Pro, this was because VMWare seemed to be having some issues and it was a tad simpler to use. Downloaded the same windows 7 iso. Everything worked great, except my VM would crash occasionally due to my Mac overheating in the Florida heat.
I was able to monitor the sensor readings and twist my OPDA until the alignment was dead on 0.0 degrees. I loosened the bolt that seats the OPDA into the engine while it was running - only enough for it to rotate. The adjustment is very minimal. For a fine adjustment, I tightened the bolt and then lightly tapped the CAM sensor housing for the final +/- 0.1 degrees of adjustment, then secured the bolt the rest of the way. Jeep starts up immediately now, before it would take a few seconds of cranking.
I have not tried to connect the chip you mention to a ground, it seems that I may have to in order to see the other readings from the transmission etc.
Attached before/after pictures where you can see the change in the CAM/CRANK DIFFERENCE reading.

Thank you very much AndyA for the detailed writeup about the installation on a virtual machine. It was very helpfull and avoided the purchase of a separate laptop.
I installed it once on Windows 10 as you described, but did not manage to connect to any module.
Then I tried again on Linux using Virtualbox.
The micropod is OK, software is launching , but at the moment to connect to the ECM or any other module, there is no connection possible.
I suspect the micropod is not working properly, I got it from Aliexpress.
It seems to be a new batch with the TI chip correctly connected to the ground: I get continuity with ground.
Any Idea what could be wrong or how to troubleshoot?
Thanks in advance
Guillaume

I think the micropod might be problem. I will return it.
Do you have links to suppliers or sellers with known working micropod?
Thanks in advance

Hey guys!
Another one who joined the drb3 gang!
I got it running and so far it seems like it's working fine.
I have spare ecu for my XJ that I want to flash and have few questions.
1. Where do you get the files?
I understand that you would generally use tech tools for that but I don't have access to it.
2. While flashing, is there any way to write proper VIN in there?
Also, ECU I want to flash came from California Jeep that has Leak Detection Pump.
My Jeep doesn't have that so when I plug it in it starts throwing error that LDP is not working.
My thought process was to flash it with proper files for my Jeep and hope it would resolve it.
Thanks!

I think there is a Mopar subscription service where the firmware can be downloaded, but I am not totally sure. Andy
Bootcamp Windows 7 Pro 32bit works on Macbook, but I want to install it in Parallels Desktop for Mac M1. Because of no intel processor I can‘t install Win7 x86
