2. General Information
2.1 On-Board Diagnostics (OBD) II
The rst generation of On-Board Diagnostics (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”.
The OBD II system is designed to monitor emission control systems and key engine components by performing either continuous or periodic tests
of specic components and vehicle conditions. When a problem is detected, the OBD II system turns on a warning lamp (MIL) on the vehicle
instrument panel to alert the driver typically by the phrase of “Check Engine” or “Service Engine Soon”. The system will also store important
information about the detected malfunction so that a technician can accurately nd and x the problem. Here below follow three pieces of such
valuable information:
1) Whether the Malfunction Indicator Light (MIL) is commanded ‘on’ or ‘off’;
2) Which, if any, Diagnostic Trouble Codes (DTCs) are stored;
3) Readiness Monitor status.
2.2 Diagnostic Trouble Codes (DTCs)
OBD II Diagnostic Trouble Codes are codes that are stored by the on-board computer diagnostic system in response to a problem found in the
vehicle. These codes identify a particular problem area and are intended to provide you with a guide as to where a fault might be occurring within
a vehicle. OBD II Diagnostic Trouble Codes consist of a ve-digit alphanumeric code. The rst character, a letter, identies which control system
sets the code. The second character, a number, 0-3; other three characters, a hex character, 0-9 or A-F provide additional information on where
the DTC originated and the operating conditions that caused it to set. Here below is an example to illustrate the structure of the digits:
Figure 2-1
2.3 Location of the Data Link Connector (DLC)
The DLC (Data Link Connector or Diagnostic Link Connector) is typically a 16-pin connector where diagnostic code readers 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. For some Asian and
European vehicles, the DLC is located behind the ashtray and the ashtray must be removed to access the connector. If the DLC cannot be found,
refer to the vehicle’s service manual for the location.

2.4 OBD II Readiness Monitors
An important part of a vehicle’s OBD II system is the Readiness Monitors, which are indicators used to nd out if all of the emissions components
have been evaluated by the OBD II system. They are running periodic tests on specic systems and components to ensure that they are
performing within allowable limits.
Currently, there are eleven OBD II Readiness Monitors (or I/M Monitors) dened by the U.S. Environmental Protection Agency (EPA). Not all
monitors are supported in every vehicles and the exact number of monitors in any vehicle depends on the motor vehicle manufacturer’s emissions
control strategy.
Continuous Monitors — Some of the vehicle components or systems are continuously tested by the vehicle’s OBD II system, while others are
tested only under specic vehicle operating conditions. The continuously monitored components listed below are always ready:
1. Misre
2. Fuel System
3. Comprehensive Components (CCM)
Once the vehicle is running, the OBD II system is continuously checking the above components, monitoring key engine sensors, watching for
engine misre, and monitoring fuel demands.
Non-Continuous Monitors — Unlike the continuous monitors, many emissions and engine system components require the vehicle to be operated
under specic conditions before the monitor is ready. These monitors are termed non-continuous monitors and are listed below:
1) EGR System
2) O2 Sensors
3) Catalyst
4) Evaporative System
5) O2 Sensor Heater
6) Secondary air Injection
7) Heated Catalyst
8) A/C system
2.5 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. The purpose of recording
readiness status is to allow inspectors to determine if the vehicle’s OBD II system has tested all the components and/or systems.
The Powertrain Control Module (PCM) sets a monitor to “Ready” or “Complete” after an appropriate drive cycle has been performed. The
drive cycle that enables a monitor and sets readiness codes to “Ready” varies for each individual monitor. Once a monitor is set as “Ready”
or “Complete”, it will remain in this state. A number of factors, including erasing of Diagnostic Trouble Codes (DTCs) with a code reader or a
disconnected battery, can result in Readiness Monitors being set to “Not Ready”. Since the three continuous monitors are constantly evaluating,
they will be reported as “Ready” all of the time. If testing of a particular supported non-continuous monitor has not been completed, the monitor
status will be reported as “Not Complete” or “Not Ready.”
In order for the OBD monitor system to become ready, the vehicle should be driven under a variety of normal operating conditions. These
operating conditions may include a mix of highway driving and stop and go, city type driving, and at least one overnight-off period. For specic
information on getting your vehicle’s OBD monitor system ready, please consult your vehicle owner’s manual.

2.6 OBD II Denitions
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. If the MIL illuminates with a steady light, it indicates that a problem has been detected and the vehicle should be
serviced as soon as possible. Under certain conditions, the dashboard light will blink or ash. This indicates a severe problem and ashing is
intended to discourage vehicle operation. The vehicle onboard diagnostic system cannot turn the MIL off until the necessary repairs are completed
or the condition no longer exists.
DTC — Diagnostic Trouble Codes (DTC) that identies which section of the emission control system has malfunctioned.
Enabling Criteria — Also termed Enabling Conditions. They are the vehicle-specic events or conditions that must occur within the engine before
the various monitors will set, or run. Some monitors require the vehicle to follow a prescribed “drive cycle” routine as part of the enabling criteria.
Drive cycles vary among vehicles and for each monitor in any particular vehicle. Please refer to the vehicle’s factory service manual for specic
enabling procedures.
OBD II Drive Cycle — A specic mode of vehicle operation that provides conditions required to set all the readiness monitors applicable to the
vehicle to the “ready” condition. The purpose of completing an OBD II drive cycle is to force the vehicle to run its onboard diagnostics. Some form
of a drive cycle needs to be performed after DTCs have been erased from the PCM’s memory or after the battery has been disconnected. Running
through a vehicle’s complete drive cycle will “set” the readiness monitors so that future faults can be detected. Drive cycles vary depending on the
vehicle and the monitor that needs to be reset. For vehicle specic drive cycle, consult the service manual.
Freeze Frame Data — When an emissions related fault occurs, the OBD II system not only sets a code but also records a snapshot of the vehicle
operating parameters to help in identifying the problem. This set of values is referred to as Freeze Frame Data and may include important engine
parameters such as engine RPM, vehicle speed, air ow, engine load, fuel pressure, fuel trim value, engine coolant temperature, ignition timing
advance, or closed loop status.
Fuel Trim (FT) — Feedback adjustments to the base fuel schedule. Short-term fuel trim refers to dynamic or instantaneous adjustments. Long-
term fuel trim refers to much more gradual adjustments to the fuel calibration schedule than short-term trim adjustments. These long-term
adjustments compensate for vehicle differences and gradual changes that occur over time.
