Your module. The details that matter.

Stock reference 590-00320-347. Listed part reference 12591647. Check the original label and all application restrictions before ordering.

Programming and installation

VIN programming is included before shipment. Provide the full 17-character VIN through Messages. VIN programming does not remove the vehicle-specific requirements below.
