How Much Does It Cost to Fix the C1310 Code in Australia?
If you’ve recently encountered a C1310 HV System Malfunction warning in your Toyota or Lexus hybrid vehicle, you’re not alone. This error code is a common issue among hybrid owners and typically indicates a problem with your vehicle’s High Voltage (HV) system. Understanding the cost to fix this code can help you plan for repairs and avoid unnecessary expenses.
What is the C1310 HV System Malfunction Code?
The C1310 diagnostic trouble code (DTC) indicates a malfunction in your hybrid vehicle’s high voltage system. This code is usually stored in the brake control module, which receives error signals from the hybrid control ECU. When something goes wrong with the hybrid battery or associated systems, this fault code is triggered.
🚗 Vehicles Commonly Affected:
- Toyota Prius (Gen 2, 3, and 4)
- Lexus CT200h
- Lexus RX400h / RX450h
- Toyota Camry Hybrid
- Lexus IS300h / ES300h

- Vehicle may not start or drive properly
- Reduced power or fuel economy
🛠️ What Causes the C1310 Code?
The C1310 code is often a result of one or more of the following:
- Failing hybrid battery (voltage imbalance, overheating)
- Faulty inverter assembly or DC-DC converter
- Hybrid ECU issues
- Loose or corroded HV wiring/connectors
- Aftermarket hybrid battery not properly integrated
