Hello,

My Accord hybrid IMA system has stopped working. IMA, battery and engine light comes on and stays on when I exceed 2000 rpms. I replaced both batteries(12Volt and Hybrid), so it is obviously not a battery issue. Accord starts up perfect and runs perfect until it exceeds 2000 rpm's and then the hybrid battery relay turns off and the car is running on the 12 volt battery at that time. DTC codes are P1586 (Motor power inverter module current sensor, P0AC4(powertrain control module set emission code) and P15A5(motor current sensor circuit malfunction). I also had the PCM/ECM checked and it is working perfect. Last, I also replaced the main battery relay and the battery current monitoring sensor. What is the next step here other than taking it to the dealer?
