Here are a few possible causes:

1. Power or ground issue:
   There may be insufficient B+ voltage and/or ground at the vehicles OBD data link connector.
   
    
2. The vehicle is not OBD-II compliant:
   Most 1996 and newer light duty vehicles are OBD-II compliant, however, the mere presence of the 16 pin OBD data link connector does not guarantee this. Some pre-1996 vehicles, medium duty vehicles, boats and even motorcycles have the 16 pin OBD data link connector but are not OBD-II compliant.
3. Previous protocol stored:
   The MICROSCAN remembers the last communication protocol used and will try using that protocol on the next vehicle if it has not powered down. Turn off MICROSCAN between use to allow MICROSCAN to select the new correct protocol for the current vehicle.

Some GM applications wll need the switch set to D or E. If one or the other is needed it will be indicated on the screen of the Blue-Point MICROSCAN. If no switch position is indicated, it is not relevant to that application and can be left in either position.
