Connects2 CTSCT002 Steering Wheel Control Interface Instruction Manual

1. Introduction

This instruction manual provides essential information for the proper installation and operation of the Connects2 CTSCT002 Steering Wheel Control Interface. This device is designed to allow the retention of your vehicle's original steering wheel audio controls when upgrading to an aftermarket car stereo system.

Please read this manual thoroughly before attempting installation to ensure correct setup and to prevent damage to the product or your vehicle.

2. Product Overview

The Connects2 CTSCT002 is a compact electronic module that translates the signals from your vehicle's steering wheel controls into a format compatible with most aftermarket head units. It typically consists of the main interface box and vehicle-specific wiring harnesses.

This image displays the Connects2 CTSCT002 module, a black rectangular unit with the 'Connects2' logo, connected to two multi-pin ISO wiring harnesses. These harnesses are designed to integrate with a vehicle's existing wiring and an aftermarket car stereo.

The interface ensures that functions such as volume up/down, track skip, and mode selection remain accessible from your steering wheel, enhancing driving safety and convenience.

3. Compatibility

This interface is compatible with the following Citroën vehicle models and years:

• Citroën C2 (2003 - 2005)
• Citroën C3 (2002 - 2005)
• Citroën C5 (2001 - 2005)
• Citroën C8 (2003 - 2006)

It is designed for use with aftermarket car audio systems that support steering wheel control input. Please verify your aftermarket head unit's compatibility with universal steering wheel control interfaces.

4. Setup and Installation

Installation of the CTSCT002 interface requires basic knowledge of car audio wiring. If you are unsure about any steps, it is recommended to seek professional installation.

1. Safety First: Before beginning, disconnect the vehicle's negative battery terminal to prevent electrical shorts.
2. Remove Original Head Unit: Carefully remove your vehicle's factory radio to access the wiring harness.
3. Connect Vehicle Harness: Connect the vehicle-specific harness from the CTSCT002 interface to the corresponding wiring harness in your car. Ensure all connections are secure.
4. Connect Aftermarket Head Unit: Connect the other end of the CTSCT002 interface harness to your aftermarket head unit. This typically involves connecting the ISO 8-pin connector and the steering wheel control wire (often labeled 'SWC', 'Key1', or 'Remote In') to the appropriate input on your new stereo. Refer to your aftermarket head unit's manual for specific wiring details.
5. Secure Module: Find a suitable location behind the dashboard to securely mount the CTSCT002 module, ensuring it does not interfere with other components or wiring.
6. Reconnect Battery: Once all connections are made and secured, reconnect the vehicle's negative battery terminal.
7. Test Functionality: Turn on your aftermarket head unit and test all steering wheel control functions (volume, track, mode, etc.) to ensure they operate correctly.

If any functions do not work as expected, re-check all connections and consult the troubleshooting section.

5. Operating Instructions

Once correctly installed, the Connects2 CTSCT002 interface operates automatically. Your vehicle's original steering wheel audio control buttons will now control your aftermarket head unit. The functionality of each button will generally mirror its original purpose, such as:

• Volume Up/Down: Adjusts the audio output level.
• Track Up/Down: Skips to the next or previous track/station.
• Mode/Source: Cycles through available audio sources (e.g., Radio, USB, Bluetooth).

Note that some specific button behaviors might vary slightly depending on the aftermarket head unit. For example, a 'mute' button on the steering wheel might function as an 'attenuate' (lower volume significantly) button on some aftermarket stereos.

6. Maintenance

The Connects2 CTSCT002 is a sealed electronic unit and requires minimal maintenance. Ensure that the module and its connections are kept dry and free from excessive vibration or physical damage. Periodically check that all wiring connections remain secure.

7. Troubleshooting

If you encounter issues after installation, consider the following troubleshooting steps:

• No Steering Wheel Control Functionality:
  • Verify all wiring connections are firm and correctly matched according to the installation instructions and your head unit's manual.
  • Ensure the aftermarket head unit's steering wheel control input (e.g., SWC, Key1) is correctly connected to the interface.
  • Check your aftermarket head unit's settings for a steering wheel control learning function or configuration menu. Some units require manual programming.
  • Confirm vehicle compatibility with the CTSCT002 model.
• Partial Functionality (Some buttons work, others don't):
  • This can sometimes be resolved by re-running the steering wheel control learning process on your aftermarket head unit.
  • Ensure the correct patch lead (if applicable) is used between the Connects2 interface and your specific brand of aftermarket head unit.
• Intermittent Operation:
  • Check for loose connections or damaged wiring.
  • Ensure the interface module is securely mounted and not subject to excessive movement.

If problems persist after attempting these steps, it is advisable to consult a professional car audio installer or contact Connects2 customer support.
