unresponsive in the Corvette.

1.  Turn the key to the ignition position.

2.  Press and hold the programming button until LED 1 turns amber and you hear two chimes. 

When this happens, release the programming button. 

3.  Within 7 seconds, press  and hold the button that is to be learned on the steering wheel. The 

LED will turn off when the button is pressed and begin blinking when the value has been 

learned. Once the LED begins blinking, release the button. 

 

4.  Repeat step 3 for each additional function on the steering wheel. 

5.  If you come to a button in the list that your vehicle does not have, skip it by pressing the 

programming button on the interface. Any buttons not learned during this process will not 

function.

6. 

Once programming is completed, the LED will flash indicating end of programming.

7.  Test the interface for proper functionality. Whenever a SWC is pressed LED 1 on the interface 

should blink green. If any function does not work, repeat the programming steps.
