Dear Customers:

In order to solve your problems more conveniently and efficiently, and also to save your time, our company will notify the following:

1. When “communication breakdown” appears during tests, it may be with following reasons:

A. The ignition is off:

The ignition must be turned ON during the test; for very few models, the ignition must be turned OFF and the emergency flasher must be turned on according to the device prompt before communicating, otherwise the communication will fail;

B. OBD Connector is in poor contact：Try unplugging and plugging the OBD connector.

C. OBD test connector is incorrect. Select the correct OBD connector for testing：

D. The software has not been upgraded to the latest version：

To test a certain model, you must confirm that the application software version of the corresponding model is updated to the latest, and the display program and the APK also must be upgraded to the latest.

E. The network is not connected：

For some new models, our device must be connected to the server via Internet to communicate, otherwise communication will fail. If the WIFI signal is not available, try to connect to the WIFI shared by the mobile phone.

F. The test path is wrong：Exit to select the correct test path to re-enter.

G. The vehicle's own communication failure：Troubleshoot and try again.

H. The device software does not support this feature for the moment：Wait patiently for software updates.

I. Device hardware failure：It must be returned to the factory for repair (or contact us for repair).
