Setup
The ANCEL AD410Pro is designed for plug-and-play operation, requiring no internal batteries for OBD2 functions as it draws power directly from the vehicle's OBDII port. For battery testing, it connects directly to the vehicle's battery terminals.
Initial Connection for OBD2 Functions
- Locate the vehicle's 16-pin Data Link Connector (DLC), usually found under the dashboard on the driver's side.
- Ensure the vehicle's ignition is in the "OFF" position.
- Connect the AD410Pro's OBDII cable to the vehicle's DLC.
- Turn the vehicle's ignition to the "ON" position (engine can be off or running, depending on the test). The device will power on automatically.
