- “MDI DOES NOT PASS SELF TEST”

- “MDI FAILS TO POWER UP”
Normally speaking, Once the external power is applied,the MDI should power up. If the MDI does not turn on, the first thing you need to do is to check the wall plug or power cable connections. Then try to supply power to the MDI from the two different power sources, the vehicle DLC connector and the AC 12-volt Adapter.
To solve this problem, you need to check and make sure that the cables are all attached to the MDI securely and the connector pins are all clean. If you are going to connect to the vehicle DLC connector, try to power from the AC 12-volt Adapter. And if you are going to connect to the AC 12-volt Adapter, you should try to power from the vehicle DLC connector.
- “MDI TURNS OFF IMMEDIATELY WHEN DISCONNECTED FROM THE VEHICLE”
Actually, after it is disconnected form the vehicle, the MDI should stay on for a factory set time unless you press the power button. If the MDI turns off immediately once you disconnected it from the vehicle, you should power up the MDI and verify that it has the same problem when the power is removed, then replace the batteries and make sure they are properly installed. After these operation, if it still fails to be off correctly, your MDI may be damaged.
