Hybrid/EV Battery Voltage/Drive Motor A Inverter Voltage Correlation

Generic OBD-II

What it means

The hybrid/EV battery voltage and the drive motor A inverter voltage are not agreeing with each other as the control module expects. The control module compares the battery voltage with the voltage at the drive motor inverter, and they should agree closely.

Can I keep driving? Usually yes for a short trip, but power may be reduced or the car may stop without warning; get it read soon. Do not open high-voltage (orange) cables or covers yourself; leave that to a trained technician.

Common symptoms

What you'll notice

Common causes

Most likely first

  1. Faulty hybrid/EV battery
  2. Faulty drive motor A inverter
  3. Defective voltage correlation between hybrid/EV battery and drive motor A inverter
  4. Malfunctioning sensors related to hybrid/EV battery voltage and drive motor A inverter
  5. Electrical wiring or connection issues related to hybrid/EV battery and drive motor A inverter

How to diagnose & fix

Work through it in order

  1. Inspect and test the hybrid/EV battery for proper voltage levels and connections.
  2. Check the drive motor A inverter for any faults or malfunctions and repair or replace if necessary.
  3. Verify the wiring harness and connections between the hybrid/EV battery and drive motor A inverter for any damages or loose connections.
  4. If all else fails, consider replacing the hybrid/EV battery or the drive motor A inverter, depending on the specific diagnosis.
