General Information
2.1 On-Board Diagnostics (OBD) II
The first generation of On-Board Diagnostics (called OBD I) was developed by
the California Air Resources Board (CARB) 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
specific 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 “Check Engine” or “Service Engine
Soon”. The system will also store important information about the detected
malfunction so that a technician can accurately find and fix the problem. Here
below follow three pieces of such 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.
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 five-digit alphanumeric code. The first
character, a letter, identifies which control system sets the code. The other
four characters, all numbers, provide additional information on where the DTC
originated and the operating conditions that caused it to be set. Below is an
example to illustrate the structure of the digits:
Figure 2-1:
Explanation of a diagnostic trouble code.
2.3 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 the Data Link Connector is not located under the dashboard, a label should
be there revealing its 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.
Figure 2-2: The
DLC connector (left) can be found in the area of the car interior seen at
right (black arrow).
2.4 OBD II Readiness Monitors
Readiness Monitors 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 l/M Monitors)
defined by the U.S. Environmental Protection Agency (EPA). Not all monitors
are supported by all 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 specific vehicle operating conditions. The continuously monitored
components listed below are always ready
- Misfire
- Fuel System
- 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 misfire,
and monitoring fuel demands.
Non-Continuous Monitors – Unlike the continuous monitors, many emissions and
engine system components require the vehicle to be operated under specific
conditions before the monitor is ready. These monitors are termed non-
continuous monitors and are listed below:
- EGR System – exhaust Gas Recirculation for reducing greenhouse gases.
- O2 Sensors – monitor and adjust air/fuel mixture.
- Catalyst – reduces exhaust emissions.
- Evaporative System – monitors the integrity of the fuel tank system
- O2 Sensor Heater – brings O2 sensor to correct operating temperature
- Secondary air – reduces exhaust emissions.
- Heated Catalyst – brings catalyst to correct operating temperature.
- 8)A/C system – monitors system for freon leaks.
2.5 OBD II Monitor Readiness Status
OBD II systems must indicate whether or not the vehicle’s PCM’s monitoring
hascompleted testing on each emission component. Components that have been OBD
II tested will be reported as “OK”. The purpose of recording readiness status
is to allow inspectors to determine if the vehicle’s OBDII system has tested
all the emissions systems. This is handy to know before bringing vehicle to a
state emissions testing facility.
The powertrain control module (PCM) sets a monitor to “OK” after an
appropriate drive cycle has been performed. The drive cycle that enables a
Monitor and sets readiness codes to “OK” varies for each individual monitor.
Once a monitor is set as “OK”, 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 “INC” (incomplete). Since the three continuous monitors are constantly
evaluating, they will be reported as “OK” all of the time. As long as there
are no DTCs stored in memory, the vehicle is running in accordance with the
OBD II guidelines. If testing of a particular support non-continuous monitor
has not been completed or not tested, the monitor status will be reported as
“INC” (incomplete).
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 specific information on
getting your vehicle’s OBD monitor system ready, please consult your vehicle
owner’s manual.
2.6 OBD II Definitions
Powertrain Control Module (PCM) – the OBD II terminology for the on-board
computer that controls the engine and the drivetrain.
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 flash. This indicates a
severe problem and flashing is intended to discourage vehicle operation. The
vehicle onboard diagnostic system can’t turn the MIL off until necessary
repairs are completed or the condition no longer exists.
DTC – Diagnostic Trouble Codes (DTC) these identify which section of the
emission control system has malfunctioned.
Enabling Criteria – Also termed Enabling Conditions. They are the vehicle-
specific events of 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.
OBD II Drive Cycle – A specific 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 specific drive cycle, consult the
vehicle’s Owner’s 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 operating
parameters to help in identifying the problem. This set of values is referred
to as Freeze Frame Date and may include important engine is referred to as
Freeze Frame Date and may include important engine 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.
