Electronic parking break HYUNDAI Grand Santa Fé (DM)

For an Electronic Parking Brake (EPB) that stays on and won’t release on a Hyundai Grand Santa Fé (DM), the recommended way to reset or retract the EPB involves putting the system into a service mode using a diagnostic tool.

Here is a summarized procedure based on a detailed video guide for similar Hyundai Santa Fe models:

- Connect a compatible diagnostic scan tool (such as Xtool A30D) to the OBD2 port inside the vehicle.
- Turn the ignition key to the ON position without starting the engine.
- Access the EPB or brake change mode on the scan tool to activate the service mode.
- This mode retracts the electronic parking brake pistons, allowing brake maintenance or repair.
- The dashboard EPB warning light will flash indicating the system is in service mode.
- After work is done (e.g., brake pad change), exit the service mode by applying and releasing the parking brake switch 3 times.
- Turn off the ignition and remove the key.
- Test to confirm the EPB releases and engages normally.

Important notes:
- Do not try to force the brake release manually—it may damage components.
- The EPB actuator motor can seize, resulting in a persistent brake lock.
- If the system won’t reset or the EPB remains stuck, professional repair or actuator replacement may be necessary.

This method ensures safe retraction of the EPB and avoids damage to the brake system.
