Why Get Codes?

Check Hybrid System, VSC, ABS Lights Illuminating?

Check Hybrid System Message: This message is Generic and will display if anything is going wrong that causes the hybrid system to shut down. It means the hybrid computer has detected a problem, which could range from an engine issue to a regenerative braking issue to a failing hybrid battery or inverter. There are no combination of lights that specifically tell you the hybrid battery has failed. The only way to tell is to get the diagnostic trouble codes to determine what the specific reason is for the Check Hybrid System Light to illuminate.

Common hybrid battery codes point to battery pack failure or imbalance, with key codes being P0A80 (Replace Hybrid Battery Pack), P0AA6 (Voltage Isolation Fault), P0A7F (Battery Deterioration).  

Common Hybrid Battery Codes

• P0A80: Replace Hybrid Battery Pack.

• P0AA6: Hybrid Battery Voltage System Isolation Fault.

• P0A7F: Hybrid Battery Pack Deterioration.

• P3011-P3024: Indicates voltage imbalance between specific battery blocks, a key sign of module failure

What to Do

1. Get it Scanned: Use an OBD-II scanner capable of reading hybrid codes. Auto Parts stores usually do this for free.

2. Check the 12V Battery: A weak 12V battery can cause erratic hybrid system readings. This can be checked at the Auto Parts store while your there having the codes checked.

3. Replace or Repair: If you have any of the codes listed above you likely need your Hybrid Battery Replaced. Please share all the codes that are present that way we can determine if it’s just your hybrid battery or if something else is causing your battery to fail.
