Our Specialized Hybrid System Malfunction Service:
- **Advanced Diagnostics (Techstream):** Using dealer-level **Toyota Techstream** equipment to read manufacturer-specific codes (e.g., P0A80, P0A93, P3000 series) and monitor high-voltage system performance in real-time.
- **Inverter & DC/DC Converter Faults:** Diagnosing and repairing common issues such as failed **Inverter Water Pumps (P0A93)** or internal malfunctions in the Power Control Unit (PCU/Inverter), which can lead to immediate shutdown.
- **High-Voltage (HV) Battery Testing:** Detailed block-level voltage analysis to identify **weak or unbalanced cells (P3011-P3024)** or overall battery deterioration (**P0A7F/P0A80**) which often trigger the warning.
- **Cooling System Failures:** Checking the dedicated cooling circuits for the inverter and the battery. A lack of cooling is a major cause of failure and requires expert bleeding and pump replacement.
- **12V Battery Correlation:** We always test and eliminate the simple causes first. A weak **12V Auxiliary Battery (C1241)** can often mimic serious hybrid system faults by failing to properly boot the control modules.
- **High-Voltage Safety:** All work adheres to strict safety protocols for high-voltage systems, ensuring safe, compliant, and reliable repair of your vehicle.
- **Model Coverage:** We specialize in all major Toyota and Lexus hybrids, including **Prius (Gen 2, 3, 4), Auris, Yaris, RAV4 Hybrid, and Lexus CT/RX/IS models**.
