What does Brake Service UConnect setting do in Jeep Grand Cherokee?

Modern vehicles are equipped with advanced features and settings that make maintenance and servicing more convenient for both drivers and technicians. In the Jeep Grand Cherokee, one such feature is the Brake Service setting in the UConnect system, which plays a crucial role in rear brake maintenance.

In this article, we will delve into the details of the Brake Service setting, exploring its functionality and how it aids in the maintenance of the Electronic Parking Brake (EPB) system.

Accessing the Brake Service UConnect Setting:

To access the Brake Service UConnect setting in the Jeep Grand Cherokee, navigate to the “Vehicle” option on the bottom category bar of the center screen.

From there, tap on “Settings” in the top right corner and select “Brakes” from the left menu.

Within the Brakes menu, you will find the Brake Service option on the right list.

Understanding Brake Service:

The Brake Service setting in the Jeep Grand Cherokee allows users to initiate brake service, specifically for the rear brakes.

When this setting is selected, a pop-up will appear with options to proceed or cancel the service. This functionality becomes particularly important when rear brake maintenance requires the rear piston to be pushed into the rear caliper bore, a task that can only be accomplished after retracting the EPB actuator.

EPB System and Maintenance Mode:

The EPB system in the Jeep Grand Cherokee includes a unique feature called Maintenance Mode, which is accessible through the UConnect Settings. Activating Maintenance Mode is a prerequisite for tasks that involve retracting the EPB actuator, such as rear brake service.

To enter Maintenance Mode, certain conditions must be met:

  • The vehicle must be at a standstill.
  • The parking brake must be unapplied.
  • The transmission must be in PARK or NEUTRAL.

While in Maintenance Mode, the EPB Warning Light will flash continuously as long as the ignition is ON, indicating that the system is in a special maintenance state.

Performing Brake Maintenance:

Once Maintenance Mode is activated, the UConnect system will guide the user through the necessary steps to retract the EPB actuator, facilitating rear brake service. This process ensures that maintenance tasks are performed safely and efficiently.

Resetting the Parking Brake System:

After completing the required brake maintenance work, it is essential to reset the parking brake system to normal operation. To do this:

  • Ensure the vehicle is at a standstill.
  • Press the brake pedal with moderate force.
  • Apply the EPB switch.

These steps will restore the EPB system to its standard operating mode, concluding the maintenance process.


The Brake Service UConnect setting in the Jeep Grand Cherokee demonstrates how advanced vehicle systems are designed to simplify maintenance tasks for both drivers and technicians.

By providing a user-friendly interface to access the EPB Maintenance Mode, Jeep enhances the overall ownership experience and ensures that essential brake maintenance can be performed efficiently and safely. Understanding and utilizing these features contribute to the longevity and optimal performance of the vehicle’s braking system.
