As the technology evolved and the desire to improve the On-Uourd Diagnostic system increased, a new generation of On-Board Diagnostic Systems was developed. This second generation of On-Board Diagnostic Regulations is called ”OBD II” The 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 1hc OllD II system turns on a warning lamp(MlL)on the instrument panel and alerts the driver typically by the phrase “Check Engine” or “Service Engine Soon”.
