Default Steering Wheel Control Programming

IMPORTANT! The interface comes pre-programmed for the functions listed in the chart below and does not require programming unless you wish to re-assign the SWC functions to different buttons. The SWC can always be restored to default settings by pressing the program button on the side of the interface once and waiting for the timeout. PLEASE NOTE: Due to the many different possible OEM SWC configurations, some applications may need to be reprogrammed for the SWC assignments to match the button on the wheel.

Optional Steering Wheel Control Programming

If you wish to re-assign the SWC functions or utilize short press long press dual command functionality, the interface must be programmed in the specific order shown on the chart on the next page. If you come across a function in the chart that your steering wheel does not have, or you do not want to program, press and release the programming button on the side of the interface to skip that function. The LED will flash off and on confirming that you have successfully skipped that function and are ready to proceed to the next one.
Short Press Long Press Dual Command Functionality
This feature allows you to assign two aftermarket radio functions to each of the vehicle’s SWC buttons. It can be used with as many of the buttons as the user likes or none at all. When this functionality is implemented, quickly pressing and releasing a SWC button will initiate the short press command, while pressing and holding a SWC button for longer than two seconds will initiate the long press command. Please note that no long press commands are programmed by default. If you wish to assign dual command functionality to the SWC please follow the programming steps on the next page.

Programming
  1. Turn the key to the ignition position.
  2. Press and release the programming button on the side of the interface.
  3. Within 7 seconds, press the button that is to be learned on the steering wheel. The LED will turn off when the button is pressed. At this point you have two options:
  4. For short press functionality: Release the button within 1.5 seconds. The LED will turn back on.
  5. For long press functionality: Hold the button until the LED starts blinking. Release the button and the LED will go back to solid.
  6. If you need to program more buttons, repeat step 3 for each additional audio function on the steering wheel.
  7. If you come across a function in the chart that your steering wheel does not have, or you do not want to program, press and release the program button on the side of the interface to skip that function.
  8. Once programming is completed, wait seven seconds. The LED will flash three times indicating end of programming.
  9. Test the interface for proper functionality. Whenever a SWC is pressed the LED on the interface should blink. If any function does not work, repeat the programming steps.

Steering Wheel Control Re-calibration

SWC re-calibration is necessary when the SWC operation is erratic or non- existent. This process re-calibrates the SWC values to the RPK4 interface for button function assignment. The interface must be programmed in the specific order shown in the table below. If you come across a function in the chart that your steering wheel does not have you must press and release the program button on the side of the interface to skip that function. The LED will flash off and on confirming that you have successfully skipped that function and are ready to proceed to the next one.
The SWC and radio command assignments can always be restored to default values by entering re-calibration mode (Steps 1-3) and not pressing any buttons. After 7 seconds the re-calibration mode will time out and all default values will be restored.

  6. Once programming is completed, wait 7 seconds and the LED will flash three times indicating end of programming.
  7. Test the interface for proper functionality. Whenever a SWC is pressed the LED on the interface should blink. If any function does not work, repeat the programming steps.
  8. After you have re-calibrated the SWC buttons, the default SWC button assignments will be the same as what is listed in the chart on page
  9. If you wish to re-assign button functions you must also go through the programming process in the section above.
