General Information of OBDII (On-Board Diagnostics II) The OBDII 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, which will offer three pieces of valuable information:
• • Whether the Malfunction Indicator Light (MIL) is commanded “on” or “off.” • • Which, if any, Diagnostic Trouble Codes (DTCs) are stored. • • Readiness Monitor status.
