Are you just replacing items, or are you following the steps in the diagnostics?

 

yes I replaced the items in their entirety, no test before, I will go to the control steps for each element, which makes me say that a priori the set according to the seller has been functional controlled, as they are the same faults that appear I conclude that it is probably something else, but I will check now I got the manual volume 1 and 2, but with your experience it is better than any book, I know what I'm talking about mechanics there is no absolute truth.

 

hi KEITHwell I proceeded to the verification of the components MCM BCM with the anomalies dtc U0110 and U1205 at step 11-151 19 voltage test I do not have the 12v but strangely 1.47v the rest is correct but after having changed BCM MCM the 4 leds are still flashing i will make an appointment with honda to erase the faults and update the firmware.after I set the car on fire if it does not ok.

 

Did your issue get resolved with the software updates at the dealership? I have been struggling with the exact same issues, and I also do not have 12V battery voltage at the same pin, but do have continuity. I have swapped out the BCM and the MCM just arrived today, along with an expensive cable that I need to use the Honda software in order to do the needed functions for replacing the MCM.

Did you also say that you heard your IPU fan in the back start right away when you start the car? Because I do not hear that so I wonder if my fan motor has gone bad and causes the IMA system to shut down. I should find out more tomorrow when I start using the Honda iHDS software, but it would be nice to hear if your issue was resolved, as I am feeling a bit discouraged at this point.
