If the scan tool would not connect to the ECU of your vehicle, there is a chance that your vehicle is either pre-OBD2 or the vehicle has a security module that is blocking third-party scan tools for reading your vehicle.
This is a reference to check if your vehicle has an OBD2-protocol pin layout: https://obdstation.com/obd2-protocols/ . Kindly note that for vehicles made pre-2008, ports with contacts in locations of discretionary pins may indicate that the vehicle is running a pre-OBD2 proprietary protocol. Kindly contact us so that we may visually check this.
There is also a chance that this is an isolated case wherein your vehicle may have a defective diagnostic port.
