2024-2025 Jeep Compass EPB Message & Warning Lamps TSB

Owners of 2024-2025 Jeep Compass vehicles may experience a 'Service Electric Park Brake' message appearing on the Instrument Panel Cluster (IPC), alongside an EPB Fault indicator light or other warning messages. This condition, addressed by Technical Service Bulletin S2508000069, can also manifest as a flashing red brake warning lamp or multiple cluster warning lamps illuminating simultaneously. Technicians often find multiple fault codes related to the Electric Park Brake (EPB) or Anti-Lock Brake System (ABS) when diagnosing this particular Jeep Compass EPB message issue.

Symptoms You Might Notice

If your 2024-2025 Jeep Compass is affected, you might observe one or more of the following:

• A "Service Electric Park Brake" message displayed on the Instrument Panel Cluster (IPC).
• An "EPB Fault indicator light" or warning message appearing.
• The "red brake warning lamp flashing."
• Multiple cluster warning lamps illuminating on the dashboard.

Fault Codes / DTCs

When diagnosing the Jeep Compass EPB message and related warning lamps, technicians commonly find several Diagnostic Trouble Codes (DTCs) stored in the vehicle's system. These codes point to issues within the Electronic Park Brake and Anti-Lock Brake Systems:

• C10D0 Electronic Park Brake System Failure: Indicates a general fault within the EPB system.
• C10EA-01 Left Park Brake Actuator-General Electrical Failure: Points to an electrical problem with the left park brake actuator.
• C10D0-4B Electronic Park Brake Module-Over Temperature: Suggests the EPB module is operating at an elevated temperature.
• C10D0-92 Electronic Park Brake Module-Performance or Incorrect Operation: Indicates the EPB module is not performing as expected or is operating incorrectly.
• C10D0-9A Electronic Park Brake Module-Component or System Operating Conditions: Relates to specific operating conditions affecting the EPB module's components or system.
• C2222-68 Improper Power Down-Event Information: Suggests an issue with how the system powers down.
• U2006-64 EPB Status - Signal Plausibility Failure: Implies an implausible signal from the EPB status, indicating a potential communication or sensor issue.

Diagnosis and Trigger Conditions

The root cause for the Jeep Compass EPB message and associated fault codes is often traced back to improper harness routing. Specifically, the wiring harness can come into contact with the Transmission Control Module (TCM) bracket and the ABS controller connector. This contact can lead to abrasion and damage to the harness circuits, disrupting communication and operation of the EPB and ABS systems.

Technicians are advised to inspect the harness routing in these areas. The bulletin highlights specific circuits, such as Circuit D497 DB/WH and ABRADED CIRCUIT B65, which are prone to damage due to contact with vehicle components. Figures 1 and 2 in the TSB illustrate the locations of potential damage and proper harness routing.

Repair Procedure Summary

The repair for this issue involves inspecting and correcting the wiring harness routing to prevent further damage. Technicians should perform the following steps:

1. Inspect Harness Routing: Carefully examine the wiring harness near the Transmission Control Module (TCM) bracket and the ABS controller connector for any signs of contact or abrasion. Figure 1 in the bulletin provides visual guidance for identifying damaged circuits.
2. Repair Damaged Circuits: Any harness circuits found to be damaged must be repaired as needed. This ensures proper electrical continuity and communication within the EPB and ABS systems.
3. Isolate and Position Harness: The harness should be isolated and positioned correctly to prevent future contact with the TCM bracket or other components. This involves securing the harness with hold-down clips and attaching it to the brake line, as shown in Figure 2.
4. Inspect ABS Module Connector: Inspect and secure the ABS module D3863A connector to ensure there is no terminal or circuit damage affecting the BUS communication or EPB actuator circuits.

Proper routing, as depicted in the bulletin, ensures the harness is secured away from potential abrasion points, resolving the underlying cause of the Jeep Compass EPB message and warning lamps.

Important Warnings

Owners and technicians should be aware of the following important information regarding this communication:

• "This document does not authorize warranty repairs." This bulletin serves as an informational record of past experiences and does not automatically qualify for warranty coverage.
• "STAR Online does not provide any conclusions about what is wrong with the vehicle." It compiles similar cases, but the technician remains responsible for the final diagnosis and appropriate course of action.
• If a solution is not found through this procedure, technicians should "Contact STAR Center, or your Technical Assistance Center Via TechCONNECT or eCONTACT ticket."

What Owners Should Do

If your 2024-2025 Jeep Compass is displaying a "Service Electric Park Brake" message, flashing warning lamps, or any of the symptoms described, it is recommended to schedule an appointment with an authorized Jeep service center. Inform them about the specific symptoms you are experiencing and mention Technical Service Bulletin S2508000069. The dealership technician will be able to diagnose the issue, check for the relevant fault codes, and perform the necessary inspection and repair of the wiring harness.
