The OBDII adapter can not communicate with the ECU, so it cannot check out the trouble code.

Hello,

It sounds like you have an OBD fuse that is out 7.5 amp. Here is a guide to help you test the fuse once you find it from the fuse panel diagrams (Below).

Here are the wiring diagrams for the OBD2 data link connector and the fuse panel locations and identifications.

Check out the diagrams (below).

Let us know what happens and please upload pictures or videos of the problem.

Cheers, Ken
