The OBD is not working. There is no clicking.
Hi there. If the OBD port is not working then most of the time this is caused by a loss of power to the plug. The fuse to the plug needs to be checked first to see if it is blown and needs to be replaced. This is a common failure point on most cars. If the fuse is fine and there is power to the plug then the main engine computer may be bad. A more extensive test with a voltage meter would need to be done at that point.
