Note: To check whether the vehicle being tested is OBDII compliant, always refer to the Vehicle Emission Control Information (VECI) decal located under the hood or by the radiator of most vehicles. See below).

2.1.1 – READ DTCs

✓ Selecting this function allows the Scan Tool to read the DTCs

from the vehicle’s control modules. DTCs are used to help determine the cause of a problem or problems within a vehicle. These codes cause the control module to illuminate the malfunction indicator lamp (MIL) when emission-related or drivability fault occurs. MIL is also known as service engine soon or check engine lamp.

✓ READ DTCs can be done with the Key On Engine Off (KOEO) or with the Key On Engine Running (KOER).

2.1.4 - FREEZE FRAME

- 11 -

When an emission-related fault has occurs, certain vehicle conditions are recorded by the on-board computer. This information is referred to as Freeze Frame data. FREEZE FRAME is a snapshot of the operating conditions at the time of an emission-related fault had occurred.

✓ FREEZE FRAME can be overwritten by faults with a higher priority. ✓ If DTCs were erased, FREEZE FRAME may not be stored in vehicle

memory depending on vehicle.

2.1.5 - MIL STATUS When the vehicle on board computer detects a problem in the emission related systems or components, its diagnostic program will assign a fault code (DTC) and store it in its memory. It also records a “Freeze Frame” of the conditions present when the fault was found and set the Malfunction Indicator Lamp (MIL) alight. Some faults require detection for two trips in a row before the MIL is turned on.

Three typical examples of MIL are shown below:

- 12 - � ��������� � ��

- 13 - � ��������� � � ��������� ������

Definition of Trip

‘A Trip’ is define as a Key-ON, Key-OFF event in which the power-train control module (PCM) detects the following:

o • Engine coolant temperature should exceed 70 C

o • Engine coolant temperature should change more than 20 C after starting the

engine. • Engine speed should go over 400 RPM.

st When the power-train control module (PCM) detects a fault during the 1 trip, the DTC and the corresponding ‘Freeze Frame’ data are stored in the PCM’s memory.

nd The MIL will not light up until the fault is again detected during the 2 trip. Certain DTCs are capable of turning the Malfunction Indicator Light (MIL) ‘ON’ or ‘blinking’ during the first trip.

To access to this function, go to ‘New Scan’ Menu and select MIL Status icon:

ENTER Press key, the screen will display as shown:

If there is no fault in the system, then the screen will display as shown:

2.1.6 - I/M Readiness

The I/M Readiness (Inspection / Maintenance Readiness) function is used to view a snapshot of the operations on the emission system on OBD II vehicles.

✓ I/M Readiness is a very useful function. To guarantee no faults exist and to

make sure all monitors are okay or not present and no DTCs exist.

- 13 - ✓ Always refer to the vehicles service manual for the Drive Cycle operation. ✓ During normal driving conditions, the vehicle’s computer scans the

Emission system. After a specific amount of drive time (each monitor has specific driving conditions and time required), the computer’s

monitors decide if the vehicles emission system is working correctly or not as well as detecting out of range values. When the monitor’s status is:

• Has Run - vehicle was driven enough to complete the monitor.

• Has Not Run - vehicle was not driven enough to complete the

monitor.

• Don’t support- vehicle does not support that monitor.

✓ Depending on the vehicle, disconnecting or a discharged battery may erase DTCs and clear monitor status.

✓ Monitors may be cleared by:

❒ Erasing DTCs ❒ Vehicle control modules losing power

✓ I/M Readiness Monitor Status can be done with the KOER or KOEO.

Abbreviations and Descriptions for OBD II Monitors supported by the Scan Tool is given below. They are required by the United States Environmental Protection Agency (EPA). Not all monitors are supported by all vehicles.

2.1.7 – Vehicle Information (VIN)

This Vehicle Information (VIN) function allows the Scan Tool to request the vehicle’s VIN number, calibration ID(s) which identifies software version in vehicle control module(s), and calibration verification numbers (CVN(s).)

- 15 - ✓ Vehicle Information (VIN) function applies to model year 2000 and newer

OBD II compliant vehicles. ✓ The Scan Tool cannot verify if data is correct for scanned vehicles.

���� � ����� � � ��������� � �� - 15 -

✓ CVNs are calculated values required by OBD II regulations.

✓ The CVN calculation may take several minutes.

✓ CVNs are reported to determine if emission-related calibrations have been changed. Multiple CVNs may be reported for a control module.

Vehicle Manufacturer specific codes are non-uniform DTCs. Areas within each alpha designator have been made available for manufacturer-controlled DTCs such as P1xxx, P30xx, U1xxx, etc. These are fault codes (DTCs) that will not generally be used by a majority of the manufacturers due to basic system differences, implementation differences, or diagnostic strategy differences.

Each vehicle manufacturer or supplier who designs and specifies diagnostic algorithms, software, and diagnostic trouble codes are strongly encouraged to remain consistent across their product line when assigning codes in the manufacturer controlled area.

For powertrain codes, the same groupings should be used as in the ISO /SAE controlled area, i.e. 100's and 200's for fuel and air metering, 300's for ignition system or misfire, etc.

Code groupings for non-powertrain codes will be specified at a later date. While each manufacturer has the ability to define the controlled DTCs to meet their specific controller algorithms, all DTC words shall meet ISO 15031-2.

Note: Correct selection of the Manufacturer on which the vehicle being tested will provide more information in the HELP mode.
