1. What does P0ABD mean?

For a 2017 Chevrolet Bolt EV (US), DTC P0ABD is covered by GM bulletin 17NA328 when present with the listed related codes. The bulletin identifies a condition involving a code set in Hybrid Powertrain Control Module 2 (HPCM2), but the supplied evidence does not include the complete cause or repair procedure.

2. Technical explanation

P0ABD means “Hybrid/EV Battery Voltage Sensor Circuit High Voltage.” The supplied official GM/NHTSA bulletin evidence also lists P1AE6 as “Battery Energy Control Module Hybrid/EV Battery Voltage Isolation Sensor Circuit” and P1FFF as “System Isolation / Coolant Level Sensor Fault - Hybrid/EV Battery Charging System Disabled.” The available bulletin excerpt states that this condition may be caused by a set code in HPCM2; the remainder of that statement is not included in the verified evidence.

3. What system is affected?

Hybrid/EV battery voltage-sensor and isolation-related monitoring, with HPCM2 referenced in the official bulletin excerpt.

4. How serious is this code?

Not yet established by verified evidence.

5. Symptoms you may notice

  • Malfunction Indicator Lamp (MIL) illuminated.
  • P0ABD may be stored.
  • One or more of P0A0C, P0ABB, P0ABC, P1AE6, or P1FFF may also be stored.

6. Possible causes

  • The official bulletin excerpt states that the condition may be caused by a set code in Hybrid Powertrain Control Module 2 (HPCM2). Further cause detail is not present in the supplied verified evidence.
  • Not yet established by verified evidence.

7. Can I still drive the vehicle?

Not yet established by verified evidence.

8. Can I charge the vehicle?

P1FFF is described in the supplied bulletin excerpt as a Hybrid/EV Battery Charging System Disabled fault. Whether charging is disabled for P0ABD alone is not yet established by verified evidence.

9. What you can safely do

  • Arrange diagnosis by a Chevrolet/GM-qualified service facility.
  • Record all stored diagnostic trouble codes before service.
  • Do not attempt high-voltage battery, isolation-monitoring, or voltage-sensor repair based on this information.

10. Step-by-step troubleshooting

  1. Confirm whether the MIL is illuminated and retrieve all stored DTCs.
  2. Check whether P0ABD appears with P0A0C, P0ABB, P0ABC, P1AE6, or P1FFF.
  3. Have a qualified technician review GM bulletin 17NA328 and diagnose the vehicle using applicable GM service information.
