VII. Troubleshooting Guide
Normal operation for this product is indicated by both Yellow and Blue lights solid on (not blinking). If blinking occurs, please analyze and troubleshoot according to the following steps.
Trouble | Analysis | Solution |
Blue Light Slow Blink | Check if used in area with poor GPS signal, e.g., near tall buildings or underground parking | Move vehicle to location with good signal for terminal use |
Check if vehicle's windshield has metal thermal insulation film affecting signal reception | If film present, test device on another vehicle without film. If blue light solid on, issue is caused by the film. | |
Check if signal jammer or interference source exists in/around vehicle | If jammer/interference exists, remove it and try reinstalling | |
Blue Light Fast Blink | Chip failure | Return to factory for repair |
Yellow Light Fast Blink | Check if SIM card is properly installed | Check if SIM card is inserted correctly |
Check if SIM card metal contacts are dirty or have poor contact | Clean metal contacts with cloth or reinsert card several times | |
Yellow Light Slow Blink | Check if vehicle is in area with no mobile network, e.g., underground parking | Move vehicle to area with good network signal and try reinstalling |
Check if backend server is normal | Inquire with backend management platform about server status | |
Check SIM card status | Check SIM card status via the SIM card query platform | |
Check if signal jammer or interference source exists in/around vehicle | If jammer/interference exists, remove it and try reinstalling |
