What this part does
The electronic parking brake module controls the operation of the electric actuators mounted on the rear brake calipers. Situated within the vehicle electrical system, it processes signals from the driver's interior switch, ABS module, and transmission range sensor to safely apply or release holding pressure. A failing unit typically triggers an amber or red EPB warning indicator on the instrument cluster. Common symptoms of failure include a parking brake that will not release, an inability to engage the system when parked, or continuous motor operation.

Before you order
Electronic parking brake modules often require initialization or calibration using a bidirectional scan tool after installation to set the correct actuator limits. You must verify that your original unit displays the exact GRT6437E1 engineering number, as modules for different trim levels or markets are not interchangeable. It is highly recommended to inspect the associated wiring harness and rear caliper actuator motors for electrical shorts or corrosion, as external faults can damage a replacement module.
