4. Setup and Installation
The installation process involves connecting the wiring harness and configuring the CAN Bus settings on your Android head unit. The specific setup method for the Android head unit may vary; please consult your head unit vendor's manual if needed.
Step 1: Connection of Cable Adapter
- Connect Power and UART Plugs: Find the 16-pin power plug of the wiring harness and plug it into the corresponding 16-pin power socket of your Android head unit. Similarly, locate the 8-pin UART plug of the wiring harness and connect it to the 8-pin UART socket on the Android head unit.
- Connect CAN Bus Box: Locate the 20-pin CAN plug on the wiring harness. Plug this into the 20-pin socket of the provided CAN Bus Box.
Step 2: Set up CAN on Android Head Unit
This step involves configuring your Android head unit to recognize and utilize the CAN Bus data provided by the decoder.
- Access Settings: On your Android head unit, navigate to the main settings menu. Look for an icon or option labeled 'Car Settings' or similar.
- Enter Factory Settings: Within 'Car Settings', find and select 'Factory' or 'Factory Settings'. You may be prompted for a password. Common passwords include 3368, 1617, 8317, or 8888. If none of these work, please consult your Android head unit vendor for the correct password.
- Navigate to CAN Bus Settings: Once in the factory settings, locate the 'CAN bus setting' option.
- Select CAN Bus Box Manufacturer and Car Model:
- From the CAN Bus settings, select the manufacturer of your CAN Bus Box. For this product, choose 'Hiworld'.
- Next, select the correct car model and year. For this product, choose 'Toyota Yaris cross 2023'.
- Save and Reboot: After selecting the manufacturer and car model, save your settings and reboot the Android head unit for the changes to take effect.
5. Operation
Once the wiring harness and CAN Bus decoder are correctly installed and configured, your Android head unit will be able to receive various control signals from your vehicle. This enables enhanced functionality and integration:
- Steering Wheel Controls: The CAN Bus decoder translates signals from your car's steering wheel buttons, allowing you to control media playback, volume, and other functions directly from the steering wheel.
- ACC Signal: Ensures the head unit powers on and off with the vehicle's ignition.
- Reverse Gear Signal: Automatically switches the head unit to display the rearview camera feed when the vehicle is put into reverse (if a rearview camera is installed and connected).
- Parking Brake Signal: Provides the parking brake status to the head unit, which may be required for certain functions (e.g., video playback while parked).
- Lighting Signal: Allows the head unit's display brightness to adjust automatically with the car's headlights.
The specific functions available may depend on the capabilities of your Android head unit and the original CAN Bus interface of your car.
6. Maintenance
The Pinmany TYC35 wiring harness and CAN Bus decoder are designed for durability and require minimal maintenance. Follow these guidelines to ensure optimal performance:
- Keep Connections Secure: Periodically check that all connections to the Android head unit and car harness are secure and free from corrosion.
- Avoid Physical Damage: Ensure the wiring harness and CAN Bus box are not exposed to excessive heat, moisture, or physical stress that could damage the components.
- Cleanliness: Keep the area around the head unit and wiring free from dust and debris.
- Software Updates: While this product is hardware-based, ensure your Android head unit's firmware is up-to-date, as updates can sometimes improve compatibility or resolve issues related to external accessories.
7. Troubleshooting
If you encounter issues after installation, refer to the following troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Android head unit does not power on. | Loose power connection, incorrect wiring. | Check all power connections (16-pin harness to head unit, car harness to power harness). Ensure vehicle ignition is on. |
| Steering wheel controls do not work. | CAN Bus Box not connected, incorrect CAN Bus settings, incompatible head unit. | Verify the 20-pin CAN plug is securely connected to the CAN Bus Box. Recheck CAN Bus settings on the Android head unit (manufacturer: Hiworld, model: Toyota Yaris cross 2023). Ensure your head unit supports steering wheel controls via CAN Bus. |
| Rearview camera does not activate in reverse. | Reverse signal not received, camera not connected correctly. | Confirm the reverse signal wire from the harness is connected to the head unit's reverse input. Check camera connections and settings on the head unit. |
| Head unit display brightness does not adjust with car lights. | Lighting signal not received or configured. | Ensure the lighting signal wire is correctly connected. Check head unit settings for automatic brightness adjustment. |
| Intermittent functionality. | Loose connections, faulty component. | Inspect all connections for looseness. If issues persist, contact customer support. |
