The computer can be reset using an OBD-II code reader/diag unit. If the light returns then the code must be read to determine the real problem. Run1 When the battery has been disconnected or replaced, it clears the on board computer of all errors and all data. The inspection station uses data from the OBDII computer to check if the car is within compliance, so when the battery was replaced all the data was cleared. You will need to drive the car roughly 50 to 100 miles so the computer can read all the sensors on the car to see if they are in good working condition or give you another "Check Engine Light".
