This manual provides comprehensive instructions for the installation, operation, and maintenance of your Connects2 CTSHO002 Steering Wheel Control Interface. This interface is designed to integrate aftermarket car audio systems with your vehicle's existing steering wheel controls, specifically for compatible Honda Civic models.

The Connects2 CTSHO002 allows you to retain the convenience and safety of your factory steering wheel controls, enabling functions such as volume adjustment, track skipping, and even date/time settings directly from your steering wheel, enhancing your driving experience.

2. Safety Information

Please read all safety instructions carefully before attempting installation. Failure to follow these guidelines may result in damage to the product, your vehicle, or personal injury.

• Always disconnect the vehicle's negative battery terminal before beginning any electrical installation to prevent short circuits and electrical shock.
• Ensure all connections are secure and properly insulated to prevent loose wires and potential hazards.
• If you are unsure about any part of the installation process, consult a qualified professional installer.
• Do not modify the product or its components. Unauthorized modifications can void the warranty and create safety risks.
• Keep the product away from moisture, extreme temperatures, and direct sunlight.

3. Setup and Installation

The Connects2 CTSHO002 interface is designed for specific Honda Civic models. Verify compatibility with your vehicle before proceeding. The installation involves connecting the interface between your vehicle's wiring harness and your aftermarket head unit.

3.1. Package Contents

Before starting, ensure all components are present in your package:

• Connects2 CTSHO002 Interface Module
• Vehicle-specific Wiring Harness
• Universal Head Unit Patch Lead (if applicable)

Note: Some aftermarket head units may require a specific patch lead, which might be sold separately.

3.2. Installation Steps

1. Prepare the Vehicle: Ensure the vehicle's ignition is off. Disconnect the negative terminal of the vehicle's battery.
2. Remove Factory Head Unit: Carefully remove your vehicle's existing factory head unit to access the wiring harness. Refer to your vehicle's service manual for specific removal instructions.
3. Connect Interface Module:
   

   Figure 3.2.1: Connects2 CTSHO002 Interface Module and Wiring. This image shows the main interface module with its integrated wiring harness, featuring multiple color-coded connectors designed to match the vehicle's factory wiring and the aftermarket head unit.

   Connect the vehicle-specific wiring harness from the CTSHO002 interface to the corresponding connectors in your vehicle's dashboard. These typically plug directly into the factory wiring loom that was connected to your original head unit.

4. Connect to Aftermarket Head Unit: Connect the universal patch lead (if used) or the direct wiring from the CTSHO002 interface to your aftermarket head unit's steering wheel control input (often labeled SWC, Remote, or Key1/Key2). Ensure the correct wires (e.g., ACC, B+, Ground) are connected as per your head unit's manual.
5. Secure Connections: Double-check all connections for tightness and proper insulation. Use electrical tape or heat shrink tubing where necessary.
6. Test Functionality: Before fully reassembling the dashboard, reconnect the vehicle's negative battery terminal. Turn on the ignition and test the functionality of your aftermarket head unit and the steering wheel controls.
7. Reassemble Dashboard: Once confirmed working, carefully reassemble the dashboard and secure the head unit in place.

4. Operating Instructions

Once correctly installed, the Connects2 CTSHO002 interface will allow your vehicle's factory steering wheel controls to operate your aftermarket head unit. The specific functions available will depend on your vehicle's original controls and your aftermarket head unit's capabilities.

• Volume Control: Use the volume up/down buttons on your steering wheel to adjust the audio output level of your head unit.
• Track/Station Navigation: Use the track forward/backward or station seek buttons to change tracks, radio stations, or navigate menus on your head unit.
• Mode/Source Selection: If your steering wheel has a 'Mode' or 'Source' button, it will typically cycle through the available audio sources on your head unit (e.g., Radio, USB, Bluetooth, AUX).
• Call Control: For head units with Bluetooth hands-free calling, the call answer/end buttons on your steering wheel may be supported.
• Date/Time Adjustment: For compatible Honda Civic models, this interface allows for the adjustment of date and time settings via the steering wheel controls, a feature often lost when replacing the factory head unit.

Refer to your aftermarket head unit's user manual for details on how it interprets steering wheel control signals and for any specific programming or learning functions it may have.

5. Maintenance

The Connects2 CTSHO002 interface is designed for long-term, maintenance-free operation once installed. However, general care for your vehicle's electronics is recommended:

• Ensure the module and its connections remain dry and free from dust or debris.
• Avoid exposing the module to extreme temperatures or direct sunlight for prolonged periods.
• Do not attempt to open or service the module yourself. There are no user-serviceable parts inside.

6. Troubleshooting

If you experience issues with your Connects2 CTSHO002 interface, please review the following common troubleshooting steps:

• No Steering Wheel Control Functionality:
  • Verify all wiring connections are secure and correctly matched according to the installation instructions and your head unit's manual.
  • Ensure the head unit's steering wheel control input is correctly configured or "learned" if your head unit has this feature. Refer to your head unit's manual.
  • Check the vehicle's fuse box for any blown fuses related to the audio system or accessory power.
• Head Unit Not Powering Off/On Correctly (e.g., not entering sleep mode, restarting):
  • This can often be caused by incorrect wiring of the ACC (accessory) and B+ (constant power) wires. Double-check these connections to ensure they are not swapped or incorrectly wired.
• Intermittent Functionality:
  • Check for loose connections or poorly insulated wires that might be shorting out.
  • Ensure the interface module is securely mounted and not subject to excessive vibration.
• Missing Components:
  • If you believe a critical component, such as a CAN-Bus module, was missing from your package, contact your retailer or Connects2 support immediately.

If problems persist after following these steps, contact Connects2 customer support or your product retailer for further assistance.
