Figure 7.1: Troubleshooting Guide
7.1 Head Unit Powers On for a Few Seconds and Then Shuts Down Automatically
Some cars have ACC wires controlled by Canbus or feature a "delayed shut off" for radios and other components. In such cases, the car may not output stable 12V power to your radio. You may need to purchase an appropriate harness adapter that provides accessory power or supports "Retained Accessory Power" for your specific car model. Alternatively, if you prefer not to buy the adapter, you can find ACC power elsewhere in your vehicle and connect your red wire there.
Necessary conditions for powering on the unit are:
- The Red wire of our harness receives switched 12V power (Car key must be turned on).
- The Yellow wire of our harness receives 12V power.
- The Black ground wire of our harness is properly connected.
If you have an electric pen, you can test these three wires. If the ACC line (Red wire) and the B+ line (Yellow wire) are reversed during installation, the product will lose its memory function after the power is turned off.
