I am trying to revive my Honda. after a 6 month in garage, car have flat 12v battery. I have fited new battery, engine start but IMA light is on, have read dtc u0110, u0111, u1205 and u1206. With disconnected 12v battery engine still running but 12v battery not charging, only 9.5v. IMA battery have 158v. I found a lot of articles about this problem but without solution. mMy question is how to get IMA to work?
