1. What does P0BD2 mean?

For a 2017 Chevrolet Bolt EV in the US, DTC P0BD2 is identified as “Drive Motor Inverter Temperature Sensor C Circuit Range/Performance.” A GM/NHTSA manufacturer communication says this condition may be caused by a software anomaly and that an updated software calibration was released.

2. Technical explanation

Verified evidence associates P0BD2 with the drive motor power inverter module. The cited manufacturer communication groups P0BD2 with inverter temperature-sensor performance codes and states that the condition may be caused by a software anomaly. Its specified correction is updated software calibration through Hybrid Powertrain Control Module Programming.

3. What system is affected?

Drive motor power inverter module; inverter temperature-sensor monitoring.

4. How serious is this code?

Not yet established by verified evidence.

5. Symptoms you may notice

  • Malfunction indicator lamp (MIL) may illuminate.
  • A “propulsion power reduced” message may be displayed in the Driver Information Center (DIC).

6. Possible causes

  • A software anomaly may cause this condition.

7. Can I still drive the vehicle?

Not yet established by verified evidence.

8. Can I charge the vehicle?

Not yet established by verified evidence.

9. What you can safely do

  • Arrange diagnosis by a Chevrolet/GM service provider.
  • Do not attempt high-voltage inverter or temperature-sensor repairs yourself.

10. Step-by-step troubleshooting

  1. Have a qualified service provider check for P0BD2 in the driver motor power inverter module.
  2. Have the provider determine whether the applicable updated Hybrid Powertrain Control Module software calibration is available.
