⚠️ P0AA6 Isolation Fault Hybrid | HV Leak Fix London Mobile

⚠️ Got a P0AA6 Fault? High Voltage Isolation Leak Repair – Done Onsite in London

P0AA6 means your hybrid’s high voltage (HV) system has detected an electrical leak to ground — usually through the battery, inverter, or wiring harness. It’s one of the most serious hybrid faults, and if ignored, it can shut the car down or damage components.

We offer a full HV isolation test and repair service – mobile across South & East London – with no need to tow the vehicle to a dealer.

🧠 What Does P0AA6 Mean?

  • The hybrid ECU is detecting that high voltage is “leaking” to the vehicle’s chassis ground.

  • This creates a serious safety hazard – enough for the system to cut off hybrid operation.

  • You may see:

    • ⚠️ “Check Hybrid System”

    • ❌ Red triangle + car not ready

    • ⚡ Car starts with engine only (limp mode)

    • 🧱 HV system shuts down after a few minutes

🔧 Our Mobile P0AA6 Diagnosis Includes:

  • 🧪 Full high-voltage isolation resistance test using insulation tester (Megger)

  • 🔎 Pinpointing if the leak is in:

    • 🔋 HV battery

    • ⚙️ Inverter unit

    • 💥 Wiring harness

    • 🧯 A/C compressor (common leak point)

  • 📟 Code depth analysis (e.g., INF 526, INF 612, INF 613, INF 614, INF 655)

  • 🔧 Onsite component swap/testing if needed

  • 📋 Final clearance with road test & ready status check
