1. What does P287100 mean?

P287100 is documented by Volvo technical-journal evidence as an intermittent DTC in the IEM (Inverter ERAD Module), where ERAD means Electric Rear Axle Drive. Volvo directs technicians to follow the applicable Service advice; revised IEM software is referenced in the verified bulletin evidence.

2. Technical explanation

Verified Volvo/NHTSA technical-journal evidence identifies P287100 as an intermittent code reported by the IEM, the Inverter ERAD Module. The supplied evidence does not establish a fuller standardized fault definition beyond this bulletin context. The bulletin material concerns diagnosis of the Electric Rear Axle Drive (ERAD) and references revised IEM software.

3. What system is affected?

Electric Rear Axle Drive (ERAD) and the IEM (Inverter ERAD Module).

4. How serious is this code?

Not yet established by verified evidence.

5. Symptoms you may notice

  • Warning lights and chimes, including a malfunction-indicator-light/check-engine-light indication, are listed in a 2020 Volvo technical-journal source.
  • Driving poor performance or lack of power is listed in a 2020 Volvo technical-journal source.
  • All-wheel-drive/4-wheel-drive operation not working is listed in 2018 Volvo technical-journal evidence.
  • Unusual front/rear axle noise is listed in the verified technical-journal evidence.
  • Front/rear axle vibration or shake is listed in the 2018 Volvo technical-journal evidence.

6. Possible causes

  • Volvo technical-journal evidence identifies P287100 as intermittent in the IEM.
  • The verified evidence references revised IEM software. A specific underlying component failure cause is 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?

Not yet established by verified evidence.

9. What you can safely do

  • Arrange diagnosis by a Volvo-qualified service provider, particularly if warning lights, loss of power, all-wheel-drive concerns, noise, or vibration are present.
  • Report the stored code P287100 and any accompanying symptoms to the service provider.
  • Do not attempt high-voltage isolation testing, ERAD removal, electric-motor replacement, or inverter work yourself.

10. Step-by-step troubleshooting

  1. Use Volvo diagnostic procedures for the ERAD/IEM system. The verified 2020 technical-journal evidence states that the journal was developed as an overview for correct fault tracing of the ERAD.
  2. Check the current applicable Volvo technical-journal instructions and software status. The verified evidence references revised IEM software.
  3. Further owner-level troubleshooting steps are not yet established by verified evidence.

11. When to contact service

Contact a Volvo retailer or qualified Volvo service provider for diagnosis using the applicable ERAD/IEM technical-journal procedure.

12. What the service center may check

  • Confirm P287100 and any accompanying DTCs in the IEM.
  • Follow the applicable Volvo ERAD fault-tracing procedure.
  • Check IEM software status and perform calibration with VIDA where directed by Volvo procedure.
  • The verified 2020 bulletin evidence also lists high-voltage battery disconnection/connection, high-voltage-system isolation testing, ERAD removal/installation, and ERAD electric-motor replacement as workshop operations. The evidence does not establish that each operation is required for every P287100 case.

13. Possible repair or resolution

  • Revised IEM software is referenced in the verified Volvo technical-journal evidence.
  • The exact repair for an individual vehicle is not yet established by verified evidence and depends on the applicable Volvo diagnostic procedure.
