Failure to charge or start is critical. Get fast, accurate, expert diagnosis now:

🔴 **12V vs. HV Fault Isolation:** Quickly determining if the issue is a simple flat **12V battery** (which prevents the system from booting) or a major **High-Voltage system** failure.
🔴 **DC-DC Converter Check:** Diagnosis of the **DC-DC Converter** (which charges the 12V battery from the HV pack). Failure often leads to a flat 12V and no-start condition (Code P0A94).
🔴 **Inverter & Generator Faults:** Tracing charging faults back to the Inverter/Power Control Unit (PCU) or the Motor Generator (MG1) responsible for charging the HV battery.
🔴 **HV Battery Health Check:** Full assessment of the High-Voltage battery modules for internal failure or imbalance that prevents the battery from accepting a charge (Codes P0A80, P30XX).
🔴 **Cable & Connection Integrity:** Inspection of high-voltage wiring, contactors, and connections for corrosion, damage, or isolation faults (Code P0AA6).
🔴 **Advanced Fault Tracing:** Using manufacturer-level tools to pull and interpret the detailed, specific fault codes that point directly to the failed component.
