Service park brake warning light

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.

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

7. Replace EPB Module and connector.

CAUTION:
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).

NOTE:
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.
