2024-2026 Jeep Compass EPB Service Brake Message TSB

Owners of 2024-2026 Jeep Compass vehicles may experience an "MP EPB SERVICE BRAKE MESSAGE ON THE CLUSTER AND LED LIGHT ON" appearing on their instrument cluster. This message indicates an issue with the Electronic Park Brake (EPB) system. This technical service bulletin (TSB) 9100620, issued on July 1, 2025, provides guidance for technicians to diagnose and resolve this specific Jeep Compass EPB service brake message.

Symptoms

Drivers may observe the following symptoms indicating a problem with the electronic park brake system:

• An "MP EPB SERVICE BRAKE MESSAGE ON THE CLUSTER AND LED LIGHT ON" displayed on the vehicle's instrument cluster.
• The LED light on the Electronic Park Brake Switch illuminating.
• The park brake switch may not function correctly, leading to difficulties engaging or disengaging the parking brake.

Fault Codes / DTCs

When the Jeep Compass EPB service brake message appears, specific Diagnostic Trouble Codes (DTCs) may be stored or active in the vehicle's system. Technicians should look for the following codes:

• C10ED-00: Electronic Park Brake Switch LED
• C10CD-01: Electronic Park Brake Switch-General Electrical Failure
• C10EA-00: Left Park Brake Actuator
• C10EC-00: Park Brak Actuator Correlation
• C10EB-00: RIGHT PARK BRAKE ACTUATOR

Diagnosis and Trigger Conditions

Diagnosis for the Jeep Compass EPB service brake message begins by confirming the customer's reported concern. Technicians are instructed to first check the status of any Diagnostic Trouble Codes (DTCs). If DTCs are found to be 'STORED' (meaning the fault is not currently present but occurred previously), they must be cleared prior to performing any service steps. If DTCs are 'ACTIVE' (meaning the fault is currently present), the following checks are necessary:

1. Confirm Customer Concern: Verify the exact nature of the issue reported by the vehicle owner.
2. Clear Stored DTCs: If any DTCs are found to be 'STORED', clear them from the system before proceeding with further diagnostics.
3. Check Battery and Ground Connections: Ensure that the battery connectors are properly seated and secure. Also, inspect the ground connector for proper seating and good contact.
4. Module Reset: Attempt to reset the module by disconnecting the vehicle's battery for 5 minutes. This can help resolve transient electrical issues.
5. Inspect for Loose Connections: If the EPB issue persists and active DTCs are still present, thoroughly check for any loose connections at the Park Brake Switch or the Brake System Module. This inspection is crucial and must be performed before considering any component replacement.

Important Warnings

This manufacturer communication, TSB 9100620, includes critical warnings for technicians to prevent unnecessary part replacements:

• Do Not Replace Prematurely: If, after disconnecting the park brake switch and the Brake System Module, any active DTC changes its status to 'STORED', technicians are explicitly instructed to clear these DTCs and do not replace the switch. This indicates the issue was likely a temporary connection problem rather than a faulty switch.
• Review Other DTCs: If any other DTCs related to the brake system are present, such as those for the park brake actuators (C10EA-00, C10EC-00, C10EB-00), the Brake System Module must be thoroughly reviewed before deciding to replace the park brake switch.

Repair Procedure Summary

After performing all diagnostic steps (1 through 5) and confirming that the park brake switch is still not functioning correctly, only then should the switch be replaced. The primary goal of the diagnostic process outlined in TSB 9100620 is to accurately identify the root cause, ensuring that the Jeep Compass EPB service brake message is resolved efficiently and without replacing components that are not truly faulty.

Required Parts

The primary component identified in this bulletin as a potential replacement part, should all diagnostic steps fail, is the SWITCH PARKING BRAKE. The specific part number associated with this component is 6ZM50DX8A$.
