When we use the MS509 Scanner,  We should know the defination of the MS 509 parts:

 Here is the defination:

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. 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 not turn 

the MIL off until necessary repairs are completed or the condition no 

longer exists. 

DTC -- Diagnostic Trouble Codes (DTC) that identify which section 

of the emission control system has malfunctioned. 

Enabling Criteria -- Also termed Enabling Conditions. They are the 

vehicle-specific 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.  

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 7

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 is referred to as Freeze Frame Data 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. 

These all are the main skills of the  Maxiscan MS 509 Scanner.
