This is a critical fault. We use dealer-level tools to trace the exact cause. Call now:

🔴 **12V Battery Check:** Often the simplest cause of a no-start condition; we test the 12V system's health and connectivity first.
🔴 **High-Voltage Battery Assessment:** Checking for common HV faults like **P0A80** (Battery Failure) or **P30xx** (Weak Block) which prevent system activation.
🔴 **Inverter & Converter Diagnostics:** Advanced scanning for codes like **P0A93** (Inverter Cooling) or internal circuit failures in the Power Control Unit (PCU).
🔴 **Safety/Isolation Faults:** Pinpointing dangerous faults like **P0AA6** (HV System Isolation Fault), which prevent the system from energizing.
🔴 **Dealer-Level Scanning:** Using specialist diagnostic software (e.g., Toyota Techstream) to read manufacturer-specific codes the average garage cannot access.
🔴 **Clear Repair Roadmap:** Providing a precise, costed repair plan for the component failure (battery, fuse, sensor, or ECU) to get you back on the road.

Please provide your vehicle's details and the exact symptoms when you press the start button.
