2021-2023 Jeep Compass Uconnect TSR Stuck MPH TSB

Owners of 2021-2023 Jeep Compass vehicles equipped with the Uconnect 5 NAV W 10.1" Display (Sales Code UUN) may encounter a specific issue with their navigation system. This problem, detailed in Technical Service Bulletin (TSB) 08-005-25, involves the Traffic Sign Recognition (TSR) feature.

Symptoms

If you own a 2021-2023 Jeep Compass, you might observe the following symptom:

• Your Uconnect Navigation Traffic Sign Recognition (TSR) is "Uconnect Navigation Traffic Sign Recognition (TSR) stuck on Miles Per Hour, (MPH) no Kilometers Per Hour (KMH)". This means the system displays speed limits only in MPH, even when KMH is expected or desired.

Cause

The root cause of the Jeep Compass TSR stuck MPH issue is identified as outdated radio software. A software update is necessary to correct the functionality of the Traffic Sign Recognition system.

Important Warnings for Owners

• Warranty Claims: Dealers are required to perform a Vehicle Scan Report using wiTECH both before and after any software update phase. Failure to provide these reports can lead to warranty claim refusal. Ensure your dealer follows this procedure.
• USB Drive Requirements: The software update requires a 32/64GB or 8GB USB flash drive. For optimal performance and reliability, a quality, name-brand (e.g., Kingston®) flash drive is recommended over generic alternatives. The update may require a minimum of three flash drives if multiple update steps are needed.
• During Reprogramming: It is crucial that no other devices are plugged into any USB ports in the vehicle while the radio software is being reprogrammed. Connecting other devices could interfere with the process, potentially causing file loading failures and necessitating radio replacement.
• Engine Operation: During the software update, do NOT turn the engine off until the two-minute timer has expired. The engine does not need to be turned off while the radio software is updating. Similarly, do not turn off the engine immediately after the software update is completed and you are prompted to remove the USB flash drive. Wait for the radio to restart and the home screen to display, which typically takes about five minutes.

Diagnosis

To diagnose the Jeep Compass TSR stuck MPH problem, technicians will use a wiTECH Scan Tool and the diagnostic procedures available in DealerCONNECT/Service Library. They will verify that all related systems are functioning correctly. If any Diagnostic Trouble Codes (DTCs) or other symptom conditions are present, they must be recorded and addressed before proceeding with the TSB 08-005-25 repair. If the customer's concern matches the described symptom, the repair procedure should be followed.

Repair Procedure Summary

The repair involves updating the Uconnect radio software to version U35.18 using a USB flash drive. The specific steps depend on the radio's current software level (S26.8, U29.18, U31.25, or U35.18).

1. Check Current Software: The technician will check the radio's current software version by navigating to "Vehicle Settings" then "System Information" and looking for "Radio Version".
2. Determine Update Steps: Based on the current software level, the radio may require one, two, or three USB update steps. For example, most vehicles are expected to be at software level S26.8, requiring a three-step update sequence: S26.8 -> U29.18 -> U31.25 -> U35.18.
3. Download Software: The required software files (e.g., fca-my24-prod-signed-usb_update-U29.18.MASTER.RW-fullupdate.zip) are downloaded from DealerCONNECT. Technicians must ensure they select the MAC version during download, regardless of the computer's operating system (as shown in Fig. 2 and Fig. 3 of the TSB).
4. Prepare USB Drive: A blank USB flash drive (32/64GB or 8GB, formatted to NTFS) is used. The downloaded software file is copied to the root directory of the USB drive without unzipping. The USB drive should then be labeled with the bulletin number and radio Sales Codes.
5. Perform Update: With the engine on, the USB drive is inserted into the vehicle's USB port. The system will detect the update and prompt the user to press "Update Now" (Fig. 5). The update process will begin, taking approximately 60 minutes (Fig. 6). Once complete, a confirmation message will appear (Fig. 7 and Fig. 8).
6. Factory Reset: After the software update is complete, a factory reset of the Uconnect system is performed by navigating to "Vehicle →Settings →Reset →Click Factory reset". This process takes about three minutes.
7. Clear DTCs: Finally, the ignition is cycled, and any Diagnostic Trouble Codes (DTCs) that may have been set in any module due to the reprogramming are cleared using wiTECH.

Required Tools and Parts

• wiTECH or Equivalent: A diagnostic scan tool is necessary for vehicle scanning and clearing DTCs.
• USB Flash Drive: A 32/64GB or 8GB USB flash drive, preferably a quality, name-brand (e.g., Kingston®) drive, is required to transfer the software update files.

Owner Action

If your 2021-2023 Jeep Compass is experiencing the Jeep Compass TSR stuck MPH issue, you should schedule an appointment with an authorized Jeep dealership. Inform them about the specific symptom you are experiencing. The dealership technicians will perform the necessary software update as outlined in TSB 08-005-25. The total labor time for this update can range from 0.2 to 0.3 hours per step, depending on the number of update steps required.

Warranty Information

This radio software update is reimbursable within the provisions of the vehicle's warranty. Owners should confirm their vehicle's warranty status with their dealership.
