Vehicle OBD Power Supply Dependent

Vehicle Compatibility Self-Check (Important Note):
Some vehicles automatically cut power to the OBD-II port when the ignition is off. This is a vehicle manufacturer design choice, not a product defect.
How to Check Your Vehicle's OBD Port:
Check Your Vehicle's OBD Port:
1.Voltmeter Test (Most Accurate):Use a voltmeter to test for constant 12V power between Pins 16 (+) and 4/5 (-) when the car is off. If reading shows ˜12V after locking vehicle, your port supports constant power
2. Quick Accessory Test (Easy): Plug any OBD-powered device (e.g., scanner, LED charger) into port If the device remains illuminated after 5 minute
Pro Tip: Check your vehicle’s owner manual under “OBD-II Port” or “Diagnostic Connector” for power specifications specific to your make/model/year.
WHY CHECK COMPATIBILITY? Verifying your OBD port ensures:
- Continuous power supply in parking mode
- Prevents unexpected shutdowns
- Avoids returns due to vehicle-specific power design
