1. What does B22A9-17 mean?

B22A9-17 has been documented by Jeep service communications in connection with an HV battery that may not fully charge when using a home 32-amp Level 2 charger. The communications state that home electrical-system harmonics can, in some cases, inhibit charging completion.

2. Technical explanation

The verified Jeep/NHTSA communications identify B22A9-17 as one of the Integrated Dual Charger Module (IDCM) DTCs associated with an internal-performance/circuit-voltage condition described as below, above, or overcurrent. It is documented alongside B22A9-16 and B22A9-19. The communications describe a scenario in which the HV battery does not fully charge using a home 32-amp Level 2 charger; some versions specifically reference a non-Mopar Level 2 charger. Jeep states that added circuit harmonics from a home electrical system may inhibit completion of charging.

3. What system is affected?

Integrated Dual Charger Module (IDCM) and Level 2 HV-battery charging operation.

4. How serious is this code?

Not yet established by verified evidence.

5. Symptoms you may notice

  • The HV battery may not fully charge when using a home Level 2 charger.
  • A technician may find B22A9-17 stored in the IDCM.

6. Possible causes

  • Home electrical-system circuit harmonics may, in some cases, inhibit completion of charging with a 32-amp Level 2 charger.
  • Some communications specifically describe the condition with a non-Mopar 32-amp Level 2 charger.

7. Can I still drive the vehicle?

Not yet established by verified evidence.

8. Can I charge the vehicle?

Charging may fail to complete with a home 32-amp Level 2 charger. The verified communications state that Level 1 charging may be used to confirm whether the condition and DTCs are no longer present; earlier guidance also suggests Level 1 charging in these rare cases.

9. What you can safely do

  • If the condition occurs on a home 32-amp Level 2 charger, arrange diagnosis by an authorized Jeep service center.
  • Use the charger-comparison approach described in the applicable Jeep service communication rather than attempting electrical or high-voltage repairs.
  • Do not perform repairs to the home electrical system, charging equipment, or vehicle high-voltage system based on this information.

10. Step-by-step troubleshooting

  1. A technician can verify whether B22A9-17 is set in the IDCM.
  2. For communications covering home Level 2 charging generally, Jeep directs confirmation that the condition is no longer present and no DTCs set when using a Level 1 charger.
  3. For communications addressing a non-Mopar Level 2 charger, Jeep directs confirmation that the condition is no longer present and no DTCs set when using a Mopar Level 2 charger.

11. When to contact service

Contact an authorized Jeep dealer or qualified service provider if the HV battery will not fully charge and B22A9-17 is present.

12. What the service center may check

  • Check the IDCM for B22A9-17 and the associated DTCs named in the service communications.
  • Confirm the charging concern with the relevant home Level 2 charger setup.
  • Perform the charger comparison specified by the applicable Jeep communication: Level 1 charging in the general home-Level-2 guidance, or Mopar Level 2 charging where the concern involves a non-Mopar Level 2 charger.

13. Possible repair or resolution

  • Jeep's May 2022 communication states that engineering was investigating a vehicle update to improve the condition.
  • A specific completed repair, software update, or parts replacement for B22A9-17 is not established by the supplied verified evidence.
