  • Verify the antenna connection to the CM-900 module.
• System Not Functioning (e.g., no remote start):
  • Check all wiring connections to the CM-900 module for looseness or corrosion.
  • Ensure the vehicle's battery is fully charged and healthy.
  • Confirm that the vehicle is in a state that allows remote start (e.g., doors closed, hood closed, parking brake engaged if required).
• Security System False Alarms:
  • Check sensor connections and sensitivity settings.
  • Ensure all doors, hood, and trunk are fully closed.

For complex issues or if troubleshooting steps do not resolve the problem, it is highly recommended to contact a certified Compustar installer or technical support. Attempting advanced repairs without proper knowledge can void your warranty or cause further damage.
