P0A0D to no end…

I see what you are saying about my post #13. Now that we are on the same page, I’m having a hard time understanding why the diagnostic process has left me dry. I have replaced the Power Management Control ECU and I am left with the same results, meaning there is something more involved that is not in agreement with the rest of the system.

Today, I performed insulation resistance tests to ensure there was minimal leakage current in the system. All my results were exceptionally high, indicating excellent insulation with no electrical leakage at the hybrid battery.

 

I think maybe I’ll go do a load test on all of my modules the way they sit right now and see what I come up with. I do not know.

 

I definitely agree with ya. Something trickier is holding me back, but I’m not sure just yet, but I will figure it out with no doubt perhaps with a little bit of guidance and advice from the hybrid community. I went ahead and took pics of my notes from today So here’s the rundown for today that I’ve been working on, But first, to answer your Question about step 7, My voltage reading for that step was 5.7 Volts today. About 20 min ago to be exact.

I started the day with a load test on all the individual modules, just for my own peace of mind. I used a 65 W headlight bulb for three minutes Per module. Attached are my results. I was kind of just throwing them down there, so hopefully they’re not too messy to read. Same goes for the P0A0D diagnosis steps I went ahead and wrote down. I’m newer to these vehicles and I’ve learned a lot. They are a whole new breed to me but I love learning about the way the systems work so far!

I have my SC300 that’s not practical for daily driving that I’ve completely built myself set aside from the machine work on the engine and the Tig welding for the IC and 4” exhaust. I run E85 and yeah anyway, back to the subject at hand.

 

To answer your question about the fan running at all times, there happens to be 2 identical plugs 3 or so inches apart. One going up the side panel an to the front of the vehicle, and the other going down to the charcoal canister. I had them swapped!!! Why and who decided this was a good idea I’ll never know, but I should’ve looked a little closer I suppose. Thanks for asking.

For the load testing, I use 2 alligator clips fused to a 65w headlight bulb and 2 alligator clips for my multimeter as well timed for 3 minutes. I have done this an hour after grid charging the pack and I’ve also done this a week after letting it sit, (grid charge as well.)
