Many factors may cause Loss of Communication, here are some pointers specific to Autel and Java:
- Connect the J-box to the PC. An icon should appear in the PC’s system tray.
- Connect the J-box to the vehicle.
- Open the GM / AC Delco software.
- Verify you are using the same version of Java as required by GM / AC Delco.
- If the Java version on your PC is newer than the one required by GM / AC Delco, you will have to ‘rollback’ to the version required.
- If the Java version on your PC is older than the one required by GM / AC Delco, you will have to update to the version required.
- After making these changes you may want to change Java’s default settings to DISABLE automatic updates.
Although not frequent, updates for the VCI and the J-box are released and should be installed.
