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
I
ndividual 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.
