🌡️ Hybrid Inverter Cooling Fault Fix – London’s Onsite Hybrid Specialists

Is your hybrid showing a red triangle? “Check Hybrid System” message? Loud fan noise? You may have a cooling fault in the inverter system — and it must be dealt with before it damages the power electronics or causes a full shutdown.

At Fix Any Hybrid London, we offer onsite inverter cooling system repairs across London – no towing, no downtime. We come equipped with Techstream diagnostics and cooling system vac tools to fix your issue quickly and permanently.

🔥 What Is the Inverter Cooling System?

The inverter converts high-voltage DC from the battery to AC for the electric motor. It gets hot — fast — and depends on a liquid-cooled loop using an electric pump and radiator.

If it fails, the system enters failsafe mode, cuts hybrid drive, and risks permanent component damage.

⚠️ Signs of Inverter Cooling System Failure:

  • ⚠️ “Check Hybrid System” + Red Triangle

  • 🌪️ Engine fan runs loudly at full speed

  • 💧 Inverter coolant reservoir not circulating

  • 🧊 Reservoir appears still or boiling hot

  • 🧱 Codes: P0A93, P1121, or inverter overheat errors

  • 🚗 Engine forced to run nonstop to protect system

🔧 Our Mobile Repair Includes:

  • 🧠 Scan hybrid ECU & inverter temp sensors

  • 🚿 Coolant circulation test (hot soak + drive test)

  • 🔧 Replacement of inverter pump, relays, fuses

  • 💧 Inverter loop drain, flush & vacuum fill (no airlocks)

  • 🧪 Final test with live temp graphing & code clear

🛠️ Hybrid Models Commonly Affected:

  • Toyota Prius Gen 2 & 3 (P0A93 very common)

  • Lexus RX400h / CT200h / IS300h

  • Toyota Auris / CH-R / Yaris Hybrid

💡 Did You Know?

  • A failed inverter pump on a Prius can overheat the power module in under 5 minutes.

  • Airlocks from poor coolant bleeding are one of the most common causes after DIY or garage jobs.

  • We use a pressurised vacuum bleeder tool, not basic gravity fill — to ensure full cooling loop performance.
