Hello. I have a problem with a 2018 ford focus electric 33.5 kw. The car doesn't start. There is a P0AA0 (:01)-8F error in the PCM HV battery positive contactor circuit. (general electrical fault) and U0111 :00-8E loss U0111 Lost Communication with Battery Energy Control Module A.
The car does not charge, the charger reports an error, does not pass the test. Someone bent the interlock pins of the upper safety jumper, I fixed them, but still the same.
Anyone have an idea what could have happened? Should I remove the batteries, disassemble and check the contactor? He calmly deals with electric buses on a daily basis, but it's a little different there.
In fact, I'm wondering now and forscan does not search, does not communicate with the BECM module, maybe someone would have a power supply diagram, can communication with the BECM module
