Faulty Receiver Module

Faulty Radio Signal

Professional scan tools enable mechanics to look over the car's network, and run various self-tests. These are real time savers, but they can be expensive and are out of the reach of most DIYers.
If your OBD2 scanner won't start, check the voltage on terminal 16 (scan tool power) and terminal 4 (chassis ground). If they are all OK it could be that a fuse has been blown. This is among the most common causes of scan tool failure. The most straightforward fix is to replace the fuse which has blown.
