OBD II system is designed to monitor emission control systems and key engine components by performing either continuous or periodic tests of specific components and vehicle conditions. When a problem is detected, the OBD II system turns on a warning lamp （IML）on the vehicle instrument.Panel to alert the driver typically by the phrase of “check engine” or “service engine soon”.
