This code indicates hybrid battery cooling system performance. It relates to the hybrid powertrain and may affect performance, emissions, or drivability depending on the exact failure.

Is it safe to drive?

This code points to a problem that can cause damage or affect safety. Avoid driving and have the vehicle diagnosed promptly.

Most likely causes

• High-voltage component fault

  medium

  Battery modules, inverters, or drive motors can set hybrid-system codes.

• Sensor or coolant issue

  medium

  Temperature and position sensors, or cooling-system faults, are common causes.

• Wiring or connector issue

  medium

  High-voltage and low-voltage harness issues can trigger hybrid codes.
