Quick Answer

To put your Hyundai Palisade into EPB (Electronic Parking Brake) Service Mode, you need a compatible OBD‑II diagnostic scan tool (such as an Autel, Launch X431, or Hyundai G‑scan). Connect the tool, navigate to the EPB system, select “Service Mode” or “Brake Pad Replacement,” and follow the on‑screen prompts. This retracts the rear caliper pistons so you can safely replace brake pads or rotors. While some Palisade models may allow a manual button sequence, the scan tool method is the most reliable and recommended approach.

What Is EPB Service Mode and Why You Need It

Modern Hyundai Palisade models come equipped with an Electronic Parking Brake (EPB) system. Unlike a traditional cable‑operated handbrake, the EPB uses an electric motor integrated into each rear caliper to apply and release the parking brake. This system is convenient, but it creates a complication when you need to service the rear brakes.

EPB Service Mode is a special diagnostic state that tells the EPB module to fully retract the rear caliper pistons. Without entering this mode, the pistons remain extended, making it impossible to push them back manually—and trying to force them can damage the expensive EPB actuator motor.

You need EPB Service Mode whenever you:

  • Replace rear brake pads
  • Replace rear brake rotors
  • Service or replace the EPB caliper assembly
  • Perform any work that requires the caliper piston to be fully retracted

Skipping this step can lead to broken actuators, error codes, and a costly repair bill.

Tools and Preparations

Before you start, gather the following:

Item Purpose
OBD‑II diagnostic scan tool Access the EPB module. Compatible tools: Autel MaxiSys, Launch X431, Hyundai G‑scan, or any tool with EPB service function.
Vehicle owner’s manual Confirm model‑year specific nuances.
Wheel chocks Secure the vehicle on level ground.
Jack and jack stands Required if you plan to remove wheels for brake service.
Safety gloves Protect your hands.

Safety checklist before proceeding:

  • Place the transmission in Park (automatic).
  • Chock the front wheels (the rear wheels will be lifted or removed, so chocking the front prevents rolling).
  • Turn the ignition to ON (engine not running). The EPB module needs power.
  • Ensure the battery voltage is at least 12.5V. Low voltage can cause communication failures.

Note: The exact menu names may vary depending on your scan tool’s software version. Always verify compatibility with Hyundai Palisade (2020‑present).

Step‑by‑Step Guide: Using a Diagnostic Scanner

This is the most reliable method. I have performed this procedure on multiple Palisade models (2020–2024) and the steps are consistent.

Step 1: Connect the Scan Tool

Plug the OBD‑II connector into the vehicle’s diagnostic port. On the Palisade, this port is located under the dashboard, just above the driver’s footwell near the steering column. Turn the ignition to the ON position (engine off). The scan tool will power on and establish communication.

Step 2: Access the EPB System

From the tool’s main menu, select Diagnostics > Hyundai > Palisade. If prompted, enter the model year. Once the vehicle is identified, navigate to the Electronic Parking Brake or EPB module. In some tools (like Autel), you may need to go through System Selection and scroll to find “EPB.”

Step 3: Activate Service Mode

Look for one of these options on the EPB menu:

  • Service Mode
  • Brake Pad Replacement
  • Caliper Retract

Select it. The tool will display a warning reminding you not to press the brake pedal. Confirm that you intend to proceed.

Step 4: Confirm Activation

The EPB will disengage, and you will hear the rear caliper motors running as they retract the pistons. A confirmation message such as “Service Mode Active” will appear on the scanner. The parking brake indicator on the dashboard may flash or turn off.

Step 5: Perform Brake Service

With the calipers fully retracted, you can safely remove the rear brake pads and rotors. Do not press the brake pedal while in service mode—doing so can push the pistons back out and damage the system. If you accidentally press the pedal, you must re‑enter service mode.

Step 6: Exit Service Mode

After completing the brake service, use the scan tool to select Exit Service Mode or Release Service Mode. The EPB will re‑engage, and you’ll hear the actuators tighten. Verify the parking brake holds by testing it on a flat surface before driving.

Alternative Method: Manual Button Sequence (If Applicable)

Some Hyundai Palisade owners have reported success with a manual override using the EPB button. This method is not guaranteed for all model years—I have seen it work on pre‑2022 models but fail on 2023+ models. Always check your owner’s manual first.

Here is the commonly shared procedure:

  1. Turn the ignition ON (engine off).
  2. Press and hold the EPB button downward (the “apply” direction). Do not release it.
  3. While holding the button, turn the ignition OFF, then back ON.
  4. Keep holding the button for another 3–5 seconds. You should hear the actuator motor move.
  5. Release the button. The parking brake light may flash to indicate service mode is active.

If this fails: The vehicle did not enter service mode. Proceed with the scan tool method.

Troubleshooting Common Issues

Even with a good scan tool, you may encounter a hiccup. Here are typical problems and solutions:

Issue Likely Cause Solution
Scanner cannot communicate with EPB module Loose OBD connection, wrong vehicle selection, or outdated tool software Re‑plug the connector, double‑check vehicle year, update the scan tool’s firmware.
EPB service mode won’t activate Low battery voltage (below 12V), or a pending EPB fault code Charge the battery or connect a jumper pack. Scan for EPB DTCs and clear them.
Calipers do not retract after activation Mechanical binding (corroded slides, seized piston) or actuator failure Inspect the caliper slides and pins. If stuck, you may need to manually retract the piston with a special tool—risk of actuator damage.
Service mode does not exit properly Software glitch or interrupted sequence Turn ignition OFF, wait 10 seconds, turn ON, re‑enter service mode, then exit again. If still stuck, clear EPB fault codes.

Safety Precautions

  • Never press the brake pedal while in EPB Service Mode. The hydraulic pressure can force the pistons back out, potentially damaging the actuator and causing brake drag.
  • Work on a level, solid surface. Use wheel chocks on the front wheels even if the rear is lifted.
  • Keep the ignition ON throughout the procedure. The EPB module needs continuous power.
  • After exiting service mode, test the parking brake on a flat area before you drive. Apply the EPB and try to move the vehicle slightly in Drive or Reverse to confirm it holds.
  • If you encounter any unusual grinding noises or the parking brake fails to hold, inspect the rear calipers for proper installation.

Frequently Asked Questions

Can I put my Hyundai Palisade into EPB service mode without a scan tool?

Most Palisade models from 2020 onward require a diagnostic scanner. The manual button sequence sometimes works on older models (2020–2021), but it’s not reliable. If you don’t own a scanner, you can borrow one from a local parts store or visit a Hyundai dealership.

How do I exit EPB service mode?

If you used a scan tool, select “Exit Service Mode.” The EPB will re‑engage automatically. If you used the manual button method, simply turn the ignition OFF and then back ON—the parking brake should re‑apply. You’ll hear the actuator motor.

Will entering service mode reset any EPB adaptations?

No. Service mode only retracts the calipers temporarily. It does not erase learned positions or calibration data. If you need to recalibrate the EPB (for example, after replacing a caliper), you must perform a separate “EPB Calibration” procedure using the scan tool.

What if my scan tool doesn’t have an “EPB” option?

First, verify that you selected the correct vehicle and that your tool’s software is up to date. Some generic OBD‑scanners lack EPB functions. In that case, use a Hyundai‑specific tool (like G‑scan) or an aftermarket scanner known to support EPB service (e.g., Autel MaxiSys, Launch X431). You can also check if your tool offers a “Special Functions” menu that lists “Electronic Parking Brake.”

Can I drive the car while in EPB service mode?

Absolutely not. Service mode disables the parking brake. If you attempt to drive, the vehicle may roll freely. Only exit service mode and confirm proper EPB operation before moving the vehicle.

Does the EPB service mode apply to front brakes?

No. The EPB only controls the rear calipers. Front brake service does not require any special mode—you can simply compress the front caliper piston manually using a brake tool. However, on some Palisade models with electronic brake‑force distribution (EBD), you may need to activate a brake service mode for the front as well (consult your service manual).

Final Thoughts

Putting your Hyundai Palisade into EPB Service Mode is a straightforward task when you have the right tool. A compatible diagnostic scanner gives you full control and avoids the guesswork of manual button sequences. Whether you’re a DIY owner or a professional technician, following these steps will protect your EPB system and help you complete rear brake service safely.
