Quick answer
B22A9-19 is associated with an Integrated Dual Charger Module (IDCM) internal-performance circuit-voltage condition on certain U.S. Jeep plug-in hybrid vehicles. Official Jeep communications describe cases where home electrical-system harmonics can prevent completion of charging with a 32-amp Level 2 charger.

1. What does B22A9-19 mean?
B22A9-19 is associated with an Integrated Dual Charger Module (IDCM) internal-performance circuit-voltage condition on certain U.S. Jeep plug-in hybrid vehicles. Official Jeep communications describe cases where home electrical-system harmonics can prevent completion of charging with a 32-amp Level 2 charger.
2. Technical explanation
NHTSA-posted Jeep manufacturer communications associate B22A9-19 with B22A9-16 and B22A9-17 in the IDCM. The communications describe the condition as an internal-performance circuit-voltage issue (below, above, or overcurrent). In some cases, added circuit harmonics from a home electrical system may inhibit the vehicle from completing a charge using a 32-amp Level 2 charger. The evidence specifically discusses home Level 2 charging and does not establish a general vehicle or battery failure.
3. What system is affected?
Integrated Dual Charger Module (IDCM) and AC charging operation.
4. How serious is this code?
Not yet established by verified evidence.
5. Symptoms you may notice
- The high-voltage battery may not fully charge when using a home Level 2 charger.
- B22A9-19 may be stored in the IDCM.
- Official communications also describe B22A9-16 and B22A9-17 as associated codes.
6. Possible causes
- In some cases, added circuit harmonics from the home electrical system may inhibit completion of charging with a 32-amp Level 2 charger.
- For earlier communications, the described condition involved a non-Mopar 32-amp Level 2 charger at home.
- Other causes are 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?
The verified evidence indicates that home 32-amp Level 2 charging may fail to complete in the described cases. It does not establish overall charging safety or availability under all charging conditions.
9. What you can safely do
- If the condition occurs with a home Level 2 charger, use only the charger comparison described in the applicable Jeep communication or have an authorized Jeep service center evaluate the concern.
- Do not attempt high-voltage or charger-module repair.
- Record the charger type, charging location, and whether charging completes for the service visit.
10. Step-by-step troubleshooting
- Jeep communications direct confirmation of whether the condition and DTCs are absent with an alternate charging method: a Level 1 charger in the Rev. D communication, or a Mopar Level 2 charger in certain earlier communications concerning non-Mopar Level 2 charging.
- The precise applicable comparison procedure depends on the vehicle and revision of the Jeep communication. An authorized Jeep service center should determine applicability.
- Further troubleshooting steps are not yet established by verified evidence.
11. When to contact service
Contact an authorized Jeep service center if the high-voltage battery will not fully charge at home and B22A9-19 is present, particularly with a 32-amp Level 2 charger.
12. What the service center may check
- Verify the customer concern during home Level 2 charging.
- Check the IDCM for B22A9-19 and the associated B22A9-16 and B22A9-17 codes described by Jeep.
- Perform the alternate-charger confirmation stated in the applicable Jeep communication: Level 1 charging under Rev. D, or Mopar Level 2 charging in earlier non-Mopar Level 2 guidance.
- Determine whether the DTCs no longer set during the applicable comparison test.
13. Possible repair or resolution
- Jeep's May 2022 communication stated that use of a Level 1 charger was suggested in rare cases while engineering investigated a vehicle update to improve the condition.
- The supplied evidence does not confirm a final repair, software update availability, or repair outcome for a specific vehicle.
