Hi,
Is there power to the scanner? Have you tried a different scanner? If it is only reading error, have you checked the wiring at the DLC?
I attached a pic of the DLC below. Confirm power to pin 16 and ground to pins 4 and 5. Here is a link you may find helpful when checking wiring:

Also, make sure the ECU fuse isn't blown and has power. See pic 2.
Let me know.
