Question about 2004 Hyundai Santa Fe
There's no quick solution for this. Have you checked your fuses (specifically the power-bar fuses). Have you removed the radio (audio unit) and checked wiring/connections? If you don't have the wiring diagram, you can go to HMAservice.com's web site and register and access the ETM (electrical Troubleshooting manual) for your Santa Fe (http://www.hmaservice.com/)

Tips for a great answer:
A module which communicates on the class 2 serial data circuit which supplies VIN information to the radio is replaced and not properly setup with the correct VIN information for that vehicle.
The only way to unlock the radio is by using a scan tool. Always refer to the table in this section to diagnose the "Theftlock" DTC for further information.
So what problem are you having ?

The CTD system requests the IPC to illuminate the indicator only when the ignition switch is OFF. The CTD system uses the indicator in order to identify system status. For specific CTD condition that will illuminate the security indicator, refer to Content Theft Deterrent (CTD) Description and Operation .
The IPC performs the displays test at the start of each ignition cycle. The indicator illuminates for approximately 3 seconds.
SERVICE THEFT SYSTEM The radio illuminates the SERVICE THEFT SYSTEM message when the VTD system detects a failure. The radio receives a message from the theft deterrent control module via the serial data circuit requesting illumination.
This is one you need to take to the dealer , unless you have a GM factory scan tool !
