2022 Jeep Wrangler RFHM Update Prevents Key Fob Theft

Owners of the 2022 Jeep Wrangler may be concerned about potential vehicle theft vulnerabilities related to key fob programming. Technical Service Bulletin (TSB) 08-230-25, issued on July 31, 2025, details a software enhancement for the Radio Frequency Hub Module (RFHM) designed to mitigate this risk. This update specifically targets unauthorized key fob programming, aiming to deter an "unwanted drive off of the vehicle without the customer's knowledge." This TSB applies to vehicles in North and South America, Enlarged Europe, China, India & Asia Pacific, and the Middle East & Africa markets.

Symptoms

The primary concern addressed by this TSB is the potential for unauthorized key fob programming through the RFHM. Owners might experience or be concerned about:

• "Customers may be concerned about vehicle theft due to ability of key FOBs to be programmed through RFHM."
• The risk of an "unwanted drive off of the vehicle without the customer's knowledge."

This 2022 Jeep Wrangler RFHM update is a proactive measure to enhance vehicle security.

Diagnosis

To diagnose the issue and confirm the need for the update, technicians should utilize a wiTECH Scan Tool along with the appropriate diagnostic procedures available in DealerCONNECT/Service Library. The process involves verifying that all related systems are functioning as designed.

If any Diagnostic Trouble Codes (DTCs) or other symptom conditions are present beyond those specifically addressed by this bulletin, they should be recorded and repaired first. If the customer's reported concern matches the symptoms outlined in this TSB, the technician can proceed with the repair procedure.

Repair Procedure Summary

The repair outlined in TSB 08-230-25 focuses on updating the RFHM software. The procedure involves several key steps:

1. Battery Management: Before initiating the flash process, a battery charger must be connected to the vehicle. This ensures that the battery voltage remains stable, specifically between 13.2 and 13.5 volts. It is crucial not to allow the charging voltage to climb above 13.5 volts during this operation.
2. Software Reprogramming: The RFHM is then reprogrammed with the latest available software using the wiTECH Diagnostic Application. If the flash process is interrupted or aborted for any reason, it must be restarted from the beginning. Should any issues arise during the flashing process, technicians are instructed to submit a ticket to the Helpdesk, accessible within the wiTECH Help menu.
3. Post-Programming Steps: After successful reprogramming, the vehicle's ignition must be turned to the run position (with the engine off). Technicians should wait for five seconds before clearing all Diagnostic Trouble Codes (DTCs). The wiTECH application will automatically present all DTCs after the flash, allowing them to be cleared.

This 2022 Jeep Wrangler RFHM update is crucial for maintaining vehicle security.

Important Notes for Technicians

For vehicles in the SA market only, after applying this TSB 08-230-25, it is not necessary to send DID-I or DID-A information.
