Thanks. I will keep an eye on it.

I wanted to post what I am hoping is my final update. The dealership replaced module #2 and I have taken possession of the truck. It successfully charged to 100% and the charge curve appears to be normal. On a level 2 charger, the charge current does not start to ramp down until it is over 90%...

@Mpi This is my update. It turns out that there is a second bad module. The module is on order. They allowed me to take possession of the truck until the module arrives. That turns out to be a good thing because we are expecting a decent amount of snow this weekend. I has a Ford Edge as a loaner...

I am figuring that this is exactly what my truck needs.

I did the 12V reset just to be sure. It is still at about 18.7% variance.

I believe that is exactly what is going on here. I will give them a shot and explain the issue on the 14th.

Yeah, it can't hurt at this point. I will try it this morning.

Thanks! Yeah, 18.5% variation is way out of spec!

I agree. It is pretty damn close to a 20% variance which would explain why the current is ramping down so drastically at 80%.

@TaxmanHog Would you agree that I am on the right track and 18.5% is way out of spec?

Yes, the variation is over 18.5%. Now it all makes sense to me. I know from past experience that during level 2 charging, the truck ramps down the current draw when it gets close to 100%. Now I can see why it is ramping it down (significantly) when it hits about 80%. It is basing the SOC on the...

@PJnc284 I think I figured it out. I did not realize that my Autel has access to all of those parameters. Look at the state of charge percentage between modules. It is over 18%. I am assuming it is not supposed to be that high!

Thanks. Let me check my scanner tomorrow. I think I may have that parameter and I was just not paying attention.

Yes, a friend should have access to FDRS. I would like to see the individual cell voltages but individual module SOC would be sufficient. The car scanner app does show individual module SOC? Anyone recommend a decent bluetooth OBD 2 adaptor?

I have to get access to another scanner. The scanner I have does not show the individual SOC and voltage variances. I suspect that there will be a variance as it states "rebalance in progress". I should be able to get my hands on a different scanner soon.

Sorry I forgot to add this picture...

I did another test this morning. There is something definitely wrong. I set the charge to 100% on the app. I started at 73%. The initial charging rate was 12KW on my Autel charger. Once the truck hit 80%, the rate dipped to 3.8KW. I also used my autel scanner. It stated "rebalance in progress"...

@TaxmanHog Yes, I remember that it used to taper down after 90%. I am going to monitor it closely over the weekend. I do have an appointment for January 14th at the dealer.

@mr.Magoo Thank you. I knew something was wrong. What is your temperature where you live? It has been cold as hell here in New Jersey. It has been between 15 and 20 degrees here!

OK thanks1
