Setup and Installation

Pre-Installation Checklist

• Ensure the vehicle's battery is disconnected before beginning installation.
• Verify compatibility of the SWI-CP2 with your specific vehicle and aftermarket radio model.
• Gather all necessary tools, including wire strippers, crimpers, electrical tape, and a multimeter.

DIP Switch Configuration

The SWI-CP2 features DIP switches that must be set according to your vehicle and aftermarket radio's specific requirements. Refer to the PAC website or the ControlPRO APPs (PC, iOS & Android) for the correct DIP switch settings for your application. The switches are labeled 1 through 8 and 1 through 4, and their positions (ON or OFF) determine the interface's functionality.

Wiring Connections

Carefully connect the SWI-CP2 wiring harness to your vehicle's wiring and the aftermarket radio's harness. Ensure all connections are secure and properly insulated. The module includes specific connectors for power, ground, data, and steering wheel control inputs. Consult the detailed wiring diagram provided by PAC for your specific vehicle and radio combination.

The SWI-CP2 also provides a 2 Amp, 12V ACC output, which can be utilized in data-bus applications to provide switched power to the aftermarket radio.

Initial Power-Up

After all connections are made, reconnect the vehicle's battery. The SWI-CP2 will power on and may require a button learning process to fully integrate with your steering wheel controls.

Operation

Button Learning Mode

The SWI-CP2 features a button learning mode that allows you to program the functions of your steering wheel controls. This process typically involves pressing specific buttons on the steering wheel in a sequence dictated by the interface or the ControlPRO APP. This ensures that each button performs the desired function on your aftermarket radio.

Customizable Button Functions

Beyond basic functionality, the SWI-CP2 allows for customization of button functions. This means you can assign specific actions (e.g., volume up, track skip, mode change) to your steering wheel buttons to suit your preferences, enhancing your driving experience.

Maintenance

The PAC SWI-CP2 is designed for long-term, maintenance-free operation once installed. Ensure the module is securely mounted in a dry location, away from excessive heat, moisture, or direct sunlight. Periodically check wiring connections for any signs of wear or looseness to maintain optimal performance.

Troubleshooting

Common Issues and Solutions

• No Steering Wheel Control Functionality:
  • Verify all wiring connections are correct and secure according to the PAC wiring diagram.
  • Confirm DIP switches are set correctly for your specific vehicle and radio.
  • Ensure the button learning process has been completed successfully.
  • Check the aftermarket radio's settings to ensure steering wheel control input is enabled.
• Incorrect Button Functions:
  • Re-enter the button learning mode and reprogram the functions.
  • Ensure no buttons were accidentally pressed during the learning sequence.
• Intermittent Operation:
  • Check for loose or corroded wiring connections.
  • Ensure the module is not exposed to excessive vibration or moisture.
