Dodge B2204

1. What does B2204 mean?

For certain 2024–2025 Dodge Charger vehicles in the U.S., B2204-00 is documented in official manufacturer communications as an Occupant Restraint Controller (ORC) ECU-configuration mismatch code that may be stored with an unknown/pending status. The communications also describe possible active B222D-00 for ECU unable to configure/configuration not learned.

2. Technical explanation

Verified manufacturer communications S2508000036, revisions A through E, describe the ORC setting B2204-00 in unknown status (pending) for an ECU configuration mismatch. They also state that B222D-00 may be active for an ECU that is unable to configure or whose configuration has not been learned. The supplied evidence does not establish a specific underlying failure mechanism beyond this documented configuration condition.

3. What system is affected?

Occupant Restraint Controller (ORC).

4. How serious is this code?

Unknown. The supplied verified evidence does not assign a severity level.

5. Symptoms you may notice

• B2204-00 may be stored with unknown status (pending).
• B222D-00 may be active for ECU unable to configure/configuration not learned.
• No driver-visible symptoms are established by the supplied verified evidence.

6. Possible causes

• Verified evidence identifies an ORC ECU configuration mismatch.
• Verified evidence identifies an ECU unable to configure or configuration not learned condition in connection with possible active B222D-00.
• Any further root 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 an authorized Dodge service provider.
• Provide the stored code status and any accompanying B222D-00 code information to the service provider.
• Do not attempt high-voltage or restraint-system repair procedures yourself.

10. Step-by-step troubleshooting

1. Use an appropriate diagnostic process to confirm whether B2204-00 is pending and whether B222D-00 is active. Further diagnostic steps are not established by the supplied verified evidence.
2. Check for applicability of manufacturer communication S2508000036 using the vehicle identification number (VIN) through an authorized Dodge service provider.

11. When to contact service

Contact an authorized Dodge service provider for diagnosis. This code is documented as involving the Occupant Restraint Controller and ECU configuration.

12. What the service center may check

• Confirm B2204-00 status in the Occupant Restraint Controller.
• Determine whether B222D-00 is active.
• Evaluate the ORC ECU configuration condition according to the applicable manufacturer communication. Detailed service procedures are not included in the supplied evidence.

13. Possible repair or resolution

• Not yet established by verified evidence. The supplied communications identify the reported ORC configuration conditions but do not provide repair instructions in the available evidence summary.
