2024 Jeep Compass RKE Reduced Range TSB S2408000100

Owners of the 2024 Jeep Compass may encounter various issues related to their vehicle's remote functions and tire pressure monitoring system. Manufacturer Communication S2408000100, released in September 2024, provides guidance for technicians to diagnose and resolve these concerns. The bulletin specifically addresses problems that can lead to a Jeep Compass RKE Reduced Range, remote start failures, and certain warning messages.

This communication helps technicians identify the root cause of these symptoms, often pointing to connections within the Remote Start Antenna (RSA) and Radio Frequency Hub (RFHUB) system. By following the outlined inspection and repair steps, the aim is to restore full functionality and address any related diagnostic trouble codes (DTCs).

Symptoms

Owners may notice one or more of the following symptoms, indicating a potential issue with their vehicle's remote keyless entry or related systems:

• "Remote Keyless Entry (RKE) Reduced Range"
• "Remote Start Inoperative"
• "Multiple Keyless-Go Push Attempts to Start"
• "Key Not Detected message"
• "Tire Pressure Warning Lamp On"

Fault Codes / DTCs

When diagnosing these symptoms, technicians may find specific Diagnostic Trouble Codes (DTCs) stored or active in the vehicle's system. These codes help pinpoint the area of concern:

Diagnosis / Trigger Conditions

Technicians are advised to inspect the Remote Start Antenna (RSA) at the Radio Frequency Hub (RFHUB) for any loose or damaged connections. A visual inspection of the remote start antenna connection at the rear headliner location is also crucial. The presence of any of the listed symptoms, particularly the Jeep Compass RKE Reduced Range, should prompt this detailed inspection.

Repair Procedure Summary

The repair process outlined in Manufacturer Communication S2408000100 focuses on thorough inspection and connection integrity. Technicians will:

1. Inspect Connections: Check for loose or damaged connections at the Remote Start Antenna (RSA) and the Radio Frequency Hub (RFHUB). This includes inspecting the coax cable for damage at both the RFHUB and RSA locations.
2. Secure Connections: If loose connections are found, they should be secured. This is a critical step to address the Jeep Compass RKE Reduced Range and other related issues.
3. Test and Verify: After securing connections, the system should be tested. This may involve swapping the RSA with a known good antenna to confirm proper operation.
4. Reset ECU: The Engine Control Unit (ECU) should be reset using a scan tool.
5. Verify Operation: Ensure all functions are working correctly and that no DTCs return after the repair.

Important Warnings

It is crucial to note that these inspections should be performed prior to any service parts replacements. This approach helps prevent unnecessary part replacements and ensures that the actual cause of the problem, such as a loose connection, is addressed first.

What Owners Should Know

If symptoms persist after initial testing, technicians will further investigate for aftermarket equipment that might interfere with the system. They will also check the Key FOB range using an RF tester to validate its operational strength. Owners experiencing a Jeep Compass RKE Reduced Range or any of the other listed symptoms should consult their dealership for diagnosis and repair according to Manufacturer Communication S2408000100.
