1. What does B1A10 mean?

B1A10-00 is identified in verified Jeep manufacturer communications as “RKE FOB 1 Battery Low.”

2. Technical explanation

Verified manufacturer communications identify B1A10-00 as a Radio Frequency Hub-related diagnostic code for a low Remote Keyless Entry (RKE) FOB 1 battery. A related manufacturer note states that when neither B1A10-00 nor B1A11-00 is set and there are no low-FOB-battery messages, a FOB battery replacement is unlikely to be required. That note does not establish the required repair when B1A10-00 is present.

3. What system is affected?

Remote Keyless Entry (RKE) FOB 1 / Radio Frequency Hub (RFH).

4. How serious is this code?

Not yet established by verified evidence.

5. Symptoms you may notice

  • A manufacturer communication lists B1A10-00 as “RKE FOB 1 Battery Low.”
  • MIL illumination is listed in several verified manufacturer communications among conditions associated with vehicles exhibiting one or more listed DTCs, including B1A10-00. The supplied evidence does not establish that B1A10-00 alone causes MIL illumination.

6. Possible causes

  • The verified description for B1A10-00 is “RKE FOB 1 Battery Low.”
  • Any additional underlying 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

  • Record whether the instrument cluster displays a low-FOB-battery message.
  • Have the vehicle scanned and document whether B1A10-00 is active or stored, along with any accompanying DTCs.
  • Consult an authorized Jeep service provider for vehicle-specific diagnosis.

10. Step-by-step troubleshooting

  1. Verify the exact DTC suffix. The supplied evidence identifies B1A10-00, not B1A10 without a suffix.
  2. Check for accompanying B1A11-00 and B23D7-14, which are listed alongside B1A10-00 in several manufacturer communications.
  3. Review applicable Jeep TSBs or RSUs for the specific vehicle, as directed by manufacturer communication S2408000118 revisions.
  4. Further troubleshooting steps are not yet established by verified evidence.

11. When to contact service

Contact an authorized Jeep service provider if B1A10-00 is present, if low-FOB-battery messages occur, or if related DTCs are stored.

12. What the service center may check

  • Confirm whether B1A10-00 is present in the Radio Frequency Hub, as identified in manufacturer communication S2608000010.
  • Check for B1A11-00 and B23D7-14, which are listed with B1A10-00 in multiple supplied manufacturer communications.
  • Review applicable TSBs or RSUs and update as needed, consistent with S2408000118 revisions.

13. Possible repair or resolution

  • The supplied evidence does not establish a specific repair for a vehicle with B1A10-00 present.
  • Manufacturer communication S2408000118 states that FOB battery replacement is unlikely to be needed only when B1A10-00 and B1A11-00 are not set and no low-FOB-battery message is present.
