I tried that. I’ve been driving the car now for two days the errors still persist. Still no power steering and AC as well.
The no a/c and no power steering is not normal, I’ve had one where the battery was bad and caused no power steering as that uses a lot of amperage but that doesn’t sound like your issue either. I’d start with checking the fuses for it along with the main fuse, you can unbolt it and remove it to visually check it out to see if it blew! From there though I would go through a more in depth diag to see what’s wrong. I’m sorry to hear the no a/c though at least where I am it’s been pretty hot recently! Good luck though and hopefully it’s something small!

It’s cause you did not push the brake pedal hard enough, Honda has told the technicians at least when you disconnect the battery that you have to mash the brake pedal before starting to allow communication between the VSA control unit and the BCM. If you don’t all those codes will show up. No worries though you can clear them all and then drive in a straight line under 30mph to allow the eps to register the centre position for steering and the rest of the lights will turn off! Definitely happened to me the first few battery’s I have changed on the new Honda’s haha
So mash the break pedal and start the car then drive in a straight line under 30mph?

Have you checked the battery sensor? The charge system on the dash will not show up for the vsa communication I was talking about. I would look to see if the battery sensor on the negative is unplugged or if the wires are damaged cause I haven’t seen that ever changing a battery even with lights coming on and such
