I installed the gen 4 ecu with the bundle of wires in an early 2020 Model 3. I also did the software re-install; twice The car still says that CCS capability is "Not available". What could be wrong? The car doesnt have any error messages and seems totally normal. As if I didn't do anything.

Hello, I am just wondering about the SunScreen print. After the 11 hours downtime, the battery will be empty, and as after that the mains power comes up, the internal 12V powersupply has to feed the circuit AND charge the battery. I wonder if that scenario is taken in account, because the internal 12V powersupply is very tiny and it is forbidden to add extra load ,fans etc, so the question is, can it handle the charge current?

I have a March 2018 build model 3, and I purchased a bundle of wires from this site. I followed the instructions on the youtube video, and I put in the new Gen4 ECU. After the install, and re-installing the Tesla firmware, the CCS adapter support appears in the UI. However, when I attached my Tesla UMC, it says "Charging Error - Power Not Detected". Looking in the service menu, I saw an error of "CP_a152_pilotEdgeDetectionFailed". I unplugged everything, then re-attached all of the wires connected to the ECU. It still showed the same error. When I re-installed my old Gen3 ECU, level 2 charging worked without any issues. (I never tried CCS/Supercharging, as I need level 2 charging to work). Is it possible to test my bundle of wires to make sure it's correct? Otherwise, are there any debugging tricks that I haven't found?
