Overview
OBD II On-Board Diagnostics
It is required by the EPA that all 1996 and
newer vehicles sold in the United States be
equipped with an OBD II computer system.
OBD II is an early warning system
designed to monitor engine, transmission,
and emissions control components by
performing specific diagnostic tests.
When a fault condition is detected, the
system captures important data and
activates the “Check Engine” light.
If the light comes on, the vehicle might have
a condition that wastes fuel, shortens engine
life, or causes excessive air pollution. If
the problem that caused the light to come
on is addressed, for instance a loose gas
cap is tightened, the light will go out.
If the light comes on and stays on, a minor
engine fault condition is occurring and
should be addressed as soon as possible
If the light is blinking, a severe engine
fault condition is occurring and should
be addressed immediately.
The Scan Tool connects to the vehicle’s
computer system and captures information
that can help identify the fault condition.
Vehicle Coverage
This Scan Tool is designed to work with
all OBD II compliant vehicles, including
those equipped with a CAN bus.
OBD II was installed in some 1994 and
1995 model year gasoline vehicles.
To verify if a 1994 or 1995 vehicle is
OBD II compliant, check the Vehicle
Emissions Control Information label, which
is located in the engine compartment.

Definitions
• DLC: Data Link Connector
The 16-cavity connector on the vehicle
that allows communication between the
computer system and the Scan Tool.
• Drive Cycle
A set of driving procedures that,
when met, provide the Enabling
Criteria for the I/M Monitors to run
and complete their diagnostic tests.
• Control Modules
Individual computers that operate
and monitor different systems in
the vehicle. Control Modules vary
depending on manufacturer.
• MIL: Malfunction Indicator Lamp
The vehicle’s “Check Engine”
warning light that activates
when a DTC is stored.
• DTC: Diagnostic Trouble Code
A code stored in the computer
system’s memory, which helps to
identify the fault condition that is
causing the MIL to activate.
• Freeze Frame Data
Operating conditions that are
stored when a DTC is stored.
• PID - Parameter Identification Data
Data returned by the vehicle’s
Control Modules to the Scan Tool.
I/M Monitors
Inspection and Maintenance diagnostic tests that the Control Modules
perform on specific sub-systems of the vehicle.
There are two types of Monitors:
• Continuous: Monitors that
perform tests all the time while
the engine is running.
• Non-Continuous: Monitors that require
specific operating conditions to be met
during a Drive Cycle in order for the
Monitors to run their testing sequences.
Note: Not all Monitors are
supported by all vehicles.

Diagnostic Trouble Code
A five digit alphanumeric identifier for a fault condition identified
by the OBD II system. There are three types of DTCs:
1. Pending - When a fault condition
is identified during a Drive Cycle,
but does not meet enough
criteria to activate the MIL.
If the fault condition occurs during two
consecutive Drive Cycles, it will turn into
a Stored DTC and the MIL will activate.
2. Stored - ADTC is stored when a fault
condition has occurred that meets
enough criteria to activate the MIL.
3. Permanent - A stored DTC that can only
be cleared by the OBD II system, after
repairs are made, and a set number of
Driving Cycles have been completed.
