I tried multiple ODB readers with Suzuki vehicles and found only one that works. Its name is "Vgate iCar Pro". I bought it from Aliexpress 3 years back, but you can get it from Daraz as well now. You will find multiple options for this device.
One with BT 3.0, BT 4.0, and Wi-Fi. I bought BT 4.0 but BT 3.0 will work as well. Not sure about Wi-Fi one. Never tried that.
BT is for Bluetooth and 3.0 or 4.0 are bluetooth versions.
Also, the only app that works with Suzuki vehicles is SZ Viewier A1
