Steering Wheel Control Interface Programming

Diagram: A device with a circular arrow indicating a process. It features a label "LED" next to a red indicator light, and a "Reset Button".

If the interface fails to function, press and release the reset button, then repeat the programming process from step 3 to try again.

Programming Steps

1. Open the driver's door and keep it open during the programming process. Cycle the ignition on.
2. Connect the LD-GM harness to the GM-SWC interface, and then to the vehicle's wiring harness.
3. For models with steering wheel controls:
   • For (hold1) vehicles: Press and hold the Volume Up button on the steering wheel until the LED stops flashing.
   • For (tap2) vehicles: Tap the Volume Up button on the steering wheel until the LED stops flashing.
4. Attention! To determine if your vehicle requires the Volume Up button to be held or tapped during programming, please refer to the application chart on the right side of page 1 of the included instructions.
5. The LED will flash Green & Red while the interface learns the radio. Subsequently, the LED will go out, flash, then turn solid Green.
6. Cycle the ignition off and then on, and test all functions for proper operation.
