I promised to keep the thread updated with my ongoing saga.

With the help of Six Rotors, who I am deeply grateful for all his help, it should be said!

Unfortunately, the hard drive on my SDD died a few days before it's the arrival of the replacement ECM/PCM and I spent a long time rebuild to version 149 - which was a waste of time because all the pinout and manual diagnostic checks require a Topix subscription where they didn't in the version 131 that is as previously using. So a side project to rebuild back to an older version less reliant on Topix will be my hobby for the next week or so. *hint hint*

The replacement ECU/PCM arrived and we attempted to swap it out and repgramme..no joy ECM Module Comms failure - same as before. So on the logic that two ECMs are not likely to be kaput, I am back to pinout checks; but i need SDD to guide down the ohm and voltage diagnostics, the later version SDD wants me to go to topic and download, my old version had it built-in.

So I started looking back at the PCM connectors, followed the loom to a "big square connector with a bolt in the middle of it". Undid that bolt and split the loom, I took the sheathing of the loom to start separating the loom out and it looks to me like "horrors of horrors" that there are some canbus loom repairs from a previous owner. The yellow and green twisted wires have been split and soldered back at some point. I am suspecting this could be a symptom - perhaps a dry joint but want to make sure I have before and after stats correlated against SDD before I undo the damage and redo the soldering.

More updates as they happen and things progress and of course if anyone's been there and done this, always happy to learn! I'll take soom loom snaps when it stops raining so that you can witness the hack...


PCM Not Playing

Everything else is good - except PCM

Whatever caused this, logged a lot of issues!

We have the data
it. Although the other part of me says what the hey, snip and solder and be done.

 

FHP and Wikkle wam the aame person?

Would be useful to tell us?

 

Nope - just misposted and cannot see how to delete or move the post :-(

 

Good find, must be a huge relief. What a stupid bodge. There are some proper cretins out there, i usually end up buying their vehicles
