Why is my smog check OBD 2 incomplete?
There are several reasons why the monitors may be incomplete. If your car has recently been repaired for a problem that set a DTC (check engine on) and the technician cleared the DTC, he also erased the monitors.

How does a car check its own emissions?
The ECM (engine control module or computer) checks it’s own emissions on all 1996 and newer cars by Federal law. When you disconnected the battery, the computer lost all of it’s stored data. The emissions protocols require a certain amount of stored data to determine the emissions condition of the car. This is known as ‘emissions ready’.
