# OBD2 HUD Troubleshooting Guide – Frequently Asked Questions

Having trouble with your OBD2 Heads-Up Display (HUD)? Below are answers to common issues to help you get your device up and running quickly.

## 1. **Why Isn’t My HUD Working After Installation?**

If your OBD2 HUD isn’t functioning right after setup, don’t worry—this is normal during first-time use.

**Initialization takes approximately 3 minutes** as the system reads your vehicle’s protocol. To ensure a smooth setup:

- Place your vehicle in **Park (P)** or **Neutral (N)** gear  
- Engage the **handbrake**  
- **Start the engine** to keep the car in an idle state  
- Plug the HUD securely into your vehicle’s **OBD2 port**  
- **Turn on the HUD power switch**—the device will begin scanning your car’s data  

✅ Once the screen shows your **engine coolant temperature** and **real-time fuel consumption**, initialization is complete, and your HUD is ready for regular use.

Tip: Always allow the full 3 minutes for the first-time scan—interrupting the process may cause errors.

## 2. **HUD Screen Has No Display or Power?**

If your HUD isn’t turning on:

1. **Check the OBD2 cable connection** – Ensure it’s fully inserted into the port. Try unplugging and reconnecting it firmly.
2. **Test in another vehicle** – This helps determine if the issue is with your car’s OBD2 port.
3. **Inspect your car’s OBD2 port** – If the HUD works in another vehicle but not yours, your car’s OBD2 interface may be faulty or damaged.
4. **Repair or replace the OBD2 port** if needed, then reconnect your HUD.

*Note: A loose or corroded OBD2 port is a common cause of “no power” issues.*

## 3. **HUD Won’t Shut Down or Sync with Ignition (Auto Start/Stop Issues)?**

To fix problems with automatic shutdown or startup:

1. Go to **System Settings** on your HUD  
2. Locate the **“Shutdown Mode”** option and choose the setting that matches your vehicle:

- **01. Intelligent Mode**: Automatically monitors vehicle status and powers off when the engine stops.  
- **02. ECU Communication Failure**: Recommended for **hybrid vehicles** or cars with **auto start-stop systems**.  
- **03. Low Battery Voltage**: Shuts down when battery voltage drops below the default threshold (13.2V).  
- **04. Countdown Timer**: Sets a delay (default: 15 seconds) before shutdown after ignition off—**only active when using GPS data**.

*Pro Tip: If you drive a hybrid or modern car with start-stop tech, select **Mode 02** for optimal compatibility.*
