Tips on SmartBox 3.0 J2534 PC Tool:
After installing J2534.exe, check if there is a new update available for smartbox firmware.
- Don’t do firmware update when running OEM software
- Make sure the smart box is connected with PC before the operation
- Keep smart box firmware to the latest version.
If there is a red icon on the left button, it means the device is not connected. It connects well when it turns to green.
Smartbox tool provides firmware upgrade, software upgrade and system upgrade function for SmartBox 3.0 devices. One-key for all upgrade, no separate upgrade required.
Set the SmartBox_3.0 box network IP to ensure that the box IP communicates with the local IP in the same subnet.
If the SmartBox tool software cannot connect to the LAUNCH J2534, you need to confirm whether the box IP and the local IP are in the same local area network.
If it is not in the same local area network, the device is not connected (the smart box IP is 192.168.100.1, and the local IP will also be displayed as 192.168.100.xxx):
Click [Apply], and the system will automatically configure the local IP to the same network segment as the device IP. After the configuration is complete, the device status is displayed as “Device is connected”.
Disconnect and reconnect smart box with laptop.
What if Smartbox Tool keeps showing cannot connect?
1. Make sure the LAUNCH J2534 is powered on normally and the red power indicator is on.
2. Set IP as above
3. If the problem still exists, check the driver is well installed. Go to the software installation directory, open the Drives-USB folder, double-click InstallDriver.exe installs the driver manually.
If still not connect j2534, please contact technical support.
