Toyota’s Code P0AA6-614 is an indication of a Hybrid Battery Voltage System Isolation Fault, which is when the insulation resistance of the high-voltage DC area has decreased. This issue can be caused by a variety of components, including the hybrid vehicle transaxle assembly, frame wire, hybrid vehicle converter, hybrid battery junction block assembly, No. 2 engine wire, inverter with converter assembly, and air conditioning system. To identify and resolve the issue, Toyota has released multiple service bulletins related to this code, including B0J, BLD, D0M, TMS-NTC-12060, and TMS-NTC-12139.
Causes and Solutions of Toyota Code P0AA6-614
| Cause | Solution |
|---|---|
| Hybrid Vehicle Transaxle Assembly | Replace components with new parts. |
| Frame Wire | Check connections and replace if necessary. |
| Hybrid Vehicle Converter | Inspect for any damage and replace if necessary. |
| Hybrid Battery Junction Block Assembly | Replace with a compatible part. |
