1 General Information On-Board Diagnostics (OBD) II The first generation of On-Board Diagnostics (called OBD I) was developed by the California Air Resources Board (ARB) and implemented in 1988 to monitor some of the emission control components on vehicles. As technology evolved and the desire to improve the On-Board Diagnostic system increased, a new generation of On-Board Diagnostic system was developed. This second generation of On-Board Diagnostic regulations is called "OBD II".
Figure 1-1 Location of the Data Link Connector (DLC) The DLC (Data Link Connector or Diagnostic Link Connector) is the standardized 16-cavity connector where diagnostic scan tools interface with the vehicle's on-board computer. The DLC is usually located 12 inches from the center of the instrument panel (dash), under or around the driver’s side for most vehicles. If Data Link Connector is not located under dashboard, a label should be there telling location.
OBD II Readiness Monitors An important part of a vehicle’s OBD II system is the Readiness Monitors, which are indicators used to find out if all of the emissions components have been evaluated by the OBD II system. They are running periodic tests on specific systems and components to ensure that they are performing within allowable limits. Currently, there are eleven OBD II Readiness Monitors (or I/M Monitors) defined by the U.S. Environmental Protection Agency (EPA).
The following monitors are to be used for compression ignition engines only: 1) EGR System 2) NMHC Catalyst 3) NOx Aftertreatment 4) Boost Pressure System 5) Exhaust Gas Sensor 6) PM Filter OBD II Monitor Readiness Status OBD II systems must indicate whether or not the vehicle’s PCM’s monitor system has completed testing on each component. Components that have been tested will be reported as “Ready”, or “Complete”, meaning they have been tested by the OBD II system.
OBD II Definitions Powertrain Control Module (PCM) – OBD II terminology for the on-board computer that controls engine and drive train. Malfunction Indicator Light (MIL) – Malfunction Indicator Light (Service Engine Soon, Check Engine) is a term used for the light on the instrument panel. It is to alert the driver and/or the repair technician that there is a problem with one or more of vehicle's systems and may cause emissions to exceed federal standards.
parameters such as engine RPM, vehicle speed, air flow, engine load, fuel pressure, fuel trim value, engine coolant temperature, ignition timing advance, or closed loop status. OBD II Modes of Operation Here is a basic introduction to the OBD II communication protocol. Mode byte: The first byte in the stream is the mode number. There are 9 modes for diagnostic requests, so this first byte is from 1 to 9. The first byte in the response data bytes is this same number plus 64.
4. $04 High sensor voltage threshold for switch time measurement 5. $05 Rich-to-Lean switch time in ms 6. $06 Lean-to Rich switch time in ms 7. $07 Minimum voltage for test 8. $08 Maximum voltage for test 9. $09 Time between voltage transitions in ms Mode $06 – Non-Continuously Monitored Systems test results. There are typically a minimum value, a maximum value, and a current value for each non-continuous monitor. This data is optional, and it is defined by a given vehicle make if it’s used.
