وحدة تحكم المجموعة الهجينة معيبة

The module coordinating engine, motors, battery and inverter, genuinely at fault. It should be a late conclusion, because it publishes data the whole vehicle consumes and therefore gets named by codes that originate elsewhere.

Read its own stored codes before anything else. A fault in the battery, an inverter, a motor or a contactor leaves it unable to answer normally, and the modules asking report invalid data — so the pointer codes vastly outnumber genuine module failures. This is high voltage territory: follow the manufacturer's isolation procedure before physical work. Check its supplies and earths before condemning it, since a module browning out on a poor connection behaves exactly like one that has failed, and these carry several separate feeds.
