Welcome to 2CarPros.

What I recommend is to have the computer scanned for diagnostic trouble codes. The light is a generic warning. There are several components which may have failed. The switch, park brake module, park brake actuator and many others. For me to properly direct you, I need to know the code. The code will not be a typical P type code but rather a C code. As a result, a basic scanner will not be able to read it.

Now, I will tell you we have been having a lot of rain where I am. If you are experiencing the same, there is a technical service bulletin related to water getting into the connector at the park brake module. Here is the TSB. Take a look through it and let me know if it helps.


NUMBER: 08-060-16

GROUP: Electrical

DATE: May 11, 2016

Electronic Parking Brake Module Connector Water Intrusion

This bulletin involves inspecting the parking brake module wiring harness connection for terminal corrosion and if needed, replacing the connector.


2014 - 2016 (KL) Jeep Cherokee

This bulletin applies to vehicles within the following markets/countries: NAFTA.

This bulletin applies to vehicles built on or before February 15, 2016 (MDH 0215XX).

The customer may describe that the Electronic Parking Brake (EPB) may not release and a service message is present with a Malfunction Indicator Lamp (MIL) illumination. Upon further investigation the technician may find one or more of the following Diagnostic Trouble Codes (DTCs):

C008E-00 - ECU Internal Performance.
C10CD-01 - Electronic Park Brake Switch - General Electrical Failure.
C10ED-00 - Electronic Park Brake Switch LED.

Using a Scan Tool (wiTECH) with the appropriate Diagnostic Procedures available in TechCONNECT, verify all engine systems are functioning as designed. If DTCs or symptom conditions, other than the ones listed above are present, record the issues on the repair order and repair as necessary before proceeding further with this bulletin.

If the customer describes the symptom/condition listed above or if the technician finds the DTC, perform the Repair Procedure.

6. Remove interior trim panels to allow access to the harness for EPB connector pigtail replacement (Fig. 4).

7. Replace EPB Module and connector.

The orange and yellow wires are a twisted pair for shielding purposes, take care to continue twist and at the same rate for the orange and yellow wires.

8. Perform EPB verification test Refer to the detailed service procedures available in DealerCONNECT> TechCONNECT under: Service Info> 28 - DTC-Based Diagnostics>MODULE, Electronic Park Brake (EPB)>Standard Procedure>EPB VERIFICATION TEST).

If this Electronic Control Unit (ECU) is being replaced with a new unit, a diagnostic scan tool MUST be used to align the PROXI configuration data into the new ECU. Follow the routine outlined in the diagnostic scan tool for PROXI Configuration Alignment, under Body Control Module (BCM) "Miscellaneous Functions" menu.

9. Clear all DTCs that may have been set. The wiTECH application will automatically present all DTCs after the flash and allow them to be cleared.

This isn't a recall, but only a technical service bulletin.


Let me know if this helps or if you get the diagnostic trouble codes.

Take care,
