The Data Cable LED is off even though I am plugged into the vehicle.

The fuse in the Data Cable may need to be replaced.

There may be insufficient B+ voltage and/or ground at the vehicle OBD data link connector. On OBD-I applications, connect the 12V Power Cable into the OBD-I adapter if required (see Connecting to OBD-I vehicles).

Can I use any USB micro cable with the VERDICT S3?

No. The USB micro cable is designed to work with the lid to capture the connector and provide strain relief. Other cables may connect but will not provide proper strain relief.
