2. General Information

2.1 On-Board Diagnostics (OBD) II

The first generation of On-Board Diagnostics (OBD I) was developed by the California Air Resources Board (ARB) 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 OnBoard 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 specic 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 of “Check Engine” or “Service Engine Soon”.

The system will also store important information about the detected malfunction

so that a technician can accurately nd and x the problem. Here below follow

three pieces of such valuable information:

1) Whether the Malfunction Indicator Light (MIL) is commanded ‘on’ or ‘off’;

2) Which, if any, Diagnostic Trouble Codes (DTCs) are stored;

3) 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 second character,

a number, 0-3; other three characters, a hex character, 0-9 or A-F provide

additional information on where the DTC originated and the operating conditions

that caused it to set. Here below is an example to illustrate the structure of the

digits:

LAUNCH Gear Scan Plus User Manual

Figure 2-1

2.3 Location of the Data Link Connector (DLC)

The DLC (Data Link Connector or Diagnostic Link Connector) is typically a 16-

pin connector where diagnostic code readers interface with the vehicle’s onboard 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

Data Link Connector is not located under dashboard, a label should be there

telling 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.

LAUNCH Gear Scan Plus User Manual

Figure 2-2

2.4 OBD II Readiness Monitors

An important part of a vehicle’s OBD II system is the Readiness Monitors, which

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 I/M Monitors) dened by the U.S. Environmental Protection Agency (EPA). Not all monitors are supported in every 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:

1. Misre

2. Fuel System

3. 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 misre,

and monitoring fuel demands.

Non-Continuous Monitors -- Unlike the continuous monitors, many emissions

and engine system components require the vehicle to be operated under specic conditions before the monitor is ready. These monitors are termed non-

continuous monitors and are listed below:

1) EGR System

2) O2 Sensors

3) Catalyst

4) Evaporative System

5) O2 Sensor Heater

LAUNCH Gear Scan Plus User Manual

6) Secondary air Injection

7) Heated Catalyst

8) A/C system

2.5 OBD II Monitor Readiness Status

OBD II systems must indicate whether or not the vehicle’s PCM’s monitor

system has completed testing on each component. Components that have been

tested will be reported as “Ready”, or “Complete”, meaning they have been tested by the OBD II system. The purpose of recording readiness status is to allow inspectors to determine if the vehicle’s OBD II system has tested all the

components and/or systems.

The Powertrain Control Module (PCM) sets a monitor to “Ready” or “Complete”

after an appropriate drive cycle has been performed. The drive cycle that

enables a monitor and sets readiness codes to “Ready” varies for each individual monitor. Once a monitor is set as “Ready” or “Complete”, 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 “Not Ready”. Since the three continuous monitors are constantly evaluating, they will be reported as “Ready” all of the time. If testing

of a particular supported non-continuous monitor has not been completed, the

monitor status will be reported as “Not Complete” or “Not Ready.”

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 specic information on getting your vehicle’s OBD monitor system ready, please consult your vehicle owner’s manual.

2.6 OBD II Denitions

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 ash. This indicates a

severe problem and flashing is intended to discourage vehicle operation. The

vehicle onboard diagnostic system cannot turn the MIL off until the necessary repairs are completed or the condition no longer exists.

LAUNCH Gear Scan Plus User Manual

DTC -- Diagnostic Trouble Codes (DTC) that identifies which section of the emission control system has malfunctioned.

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

specic 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. Please refer to the vehicle’s factory service manual for specic enabling procedures.

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 specic drive cycle, consult the service 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 ow, engine load, fuel pressure, fuel trim value,

engine coolant temperature, ignition timing advance, or closed loop status.

Fuel Trim (FT) - Feedback adjustments to the base fuel schedule. Short-term

fuel trim refers to dynamic or instantaneous adjustments. Long-term fuel trim refers to much more gradual adjustments to the fuel calibration schedule than short-term trim adjustments. These long-term adjustments compensate for vehicle differences and gradual changes that occur over time.

5.3 OBDII Diagnosis

This option presents a quick way to check for DTCs, isolate the cause of the illuminated Malfunction Indicator Lamp (MIL), check monitor status prior to

emissions certification testing, verify repairs, and perform a number of other services that are emission-related.

On the Job menu, press [OBD II] to enter system, the screen will automatically

navigate to the Monitor status screen.

Tap [OK], the following function list appears.

1. Read Codes

This option is used to identify which section of the emission control system has malfunctioned.

2. Erase Codes

After reading the retrieved codes from the vehicle and certain repairs have been

carried out, you can use this function to erase the codes from the vehicle. Before

performing this function, please be sure the vehicle’s ignition key is in the ON position with the engine off.

*Notes:

• Before performing this function, make sure to retrieve and record the trouble codes.

• After clearing, you should retrieve trouble codes once more or turn ignition on and retrieve codes again. If there are sll some trouble codes in the system, please

troubleshoot the code using a factory diagnosis guide, then clear the code and recheck.

3. I/M Readiness

An important part of a vehicle’s OBD II system is the Readiness Monitors, which

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.

LAUNCH Gear Scan Plus User Manual

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:

1. Misre

2. Fuel System

3. 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 misre,

and monitoring fuel demands.

Non-Continuous Monitors -- Unlike the continuous monitors, many emissions

and engine system components require the vehicle to be operated under specic conditions before the monitor is ready. These monitors are termed non-

continuous monitors and are listed below:

1) EGR System

2) O2 Sensors

3) Catalyst

4) Evaporative System

5) O2 Sensor Heater

6) Secondary air Injection

7) Heated Catalyst

8) A/C system

I/M refers to Inspection and Maintenance that is legislated by the Government to meet federal clean-air standards. I/M Readiness indicates whether or not the

various emissions-related systems on the vehicle are operating properly and are

ready for Inspection and Maintenance testing.

The purpose of the I/M Readiness Monitor Status is to indicate which of the

vehicle’s Monitors have run and completed their diagnosis and testing, and which ones have not yet run and completed testing and diagnosis of their designated sections of the vehicle’s emissions system.

The I/M Readiness Monitor Status function also can be used (after repair of

a fault has been performed) to confirm that the repair has been performed

correctly, and/or to check for Monitor Run Status.

This function can also be done by tapping [I/M Readiness] directly on the Job

Menu.

4. Data Stream

This option retrieves and displays live data and parameters from the vehicle’s ECU.

5. View Freeze Frame

When an emission-related fault occurs, certain vehicle conditions are recorded

by the on-board computer. This information is referred to as freeze frame data.

Freeze Data is a snapshot of the operating conditions at the time of an emission-

related fault.

*Note: If DTCs were erased, Freeze Data may not be stored in vehicle memory

depending on vehicle.

6. O2 sensor test

The results of O2 sensor test are not live values but instead the results of the

ECU’s last O2 sensor test. For live O2 sensor readings, refer to any of the live

sensor screens such as Graph Screen.

Not all test values are applicable to all vehicles. Therefore, the list generated

will vary depending on vehicle. In addition, not all vehicles support the Oxygen

Sensors screen.

7. On-board monitor test

This function can be utilized to read the results of on-board diagnostic monitoring

tests for specic components/systems.

8. EVAP System Test

The EVAP test function lets you initiate a leak test for the vehicle’s EVAP

system. The tool does not perform the leak test, but signals to vehicle’s on-board

computer to initiate the test. Before using the system test function, refer to the

vehicle’s service repair manual to determine the procedures necessary to stop the test.

9. Vehicle Info

This option displays the vehicle information, such as VIN (Vehicle Identication Number), CID (Calibration ID) and CVN (Calibration Verication Number).

SAR Information Statement

The product is designed and manufactured not to exceed the emission limits for exposure to Radio

frequency (RF) energy set by the Federal Communications Commission of the U.S. Government.

These limits are part of comprehensive guidelines and establish permitted levels of RF energy for the

general population. The guidelines are based on standards that were developed by independent

scientific organizations through periodic and thorough evaluation of scientific studies. The standards

include a substantial safety margin designed to assure the safety of all persons, regardless of age and

health. The exposure standard for wireless mobile phones employs a unit of measurement known as

the Specific Absorption Rate, or SAR. The SAR limit set by the FCC is 1.6 W/kg. Tests for SAR are

conducted with the product transmitting at its highest certified power level in all tested frequency

bands. Although the SAR is determined at the highest certified power level, the actual SAR level of

the product while operating can be well below the maximum value. This is because the product is

designed to operate at multiple power levels so as to use only the power required to reach the network.

In general, the closer you are to a wireless base station antenna, the lower the power output. Before a

product model is available for sale to the public, it must be tested and certified to the FCC that it does

not exceed the limit established by the government adopted requirement for safe exposure. The tests

are performed in positions and locations (e.g., at the ear and worn on the body) as required by the FCC

for each model. The highest SAR value for this model product when tested for use worn on the body,

as described in this user guide, when properly worn on the body is W/kg. (Body-worn

0.583

measurements differ among phone models, depending upon available accessories and FCC

requirements). While there may be differences between the SAR levels of various product and at

various positions, they all meet the government requirement for safe exposure. The FCC has granted

an Equipment Authorization for this model product with all reported SAR levels evaluated as in

compliance with the FCC RF exposure guidelines. SAR information on this model product is on file

with the FCC and can be found under the Display Grant section of http://www.fcc.gov/oet/fccid after

searching on.

FCC ID: Additional information on Specific Absorption Rates (SAR) can be

2APTR-GSPLUS

found on the Cellular Telecommunications Industry Asso-ciation (CTIA) web-site at

https://www.ctia.org/ In the United States and Canada, the SAR limit is 1.6 watts/kg (W/kg) averaged

over one gram of tissue. The standard incorporates a sub-stantial margin of safety to give additional

protectionfor the public and to account for any variations in measurements.

Body-worn Operation

This device was tested for typical body-worn operations. To comply with RF exposure requirements,

a minimum separation distance of 0mm is used between the user’s body and the handset, including

the antenna. Third-party belt-clips, holsters, and similar accessories used by this device should not

contain any metallic components. Body-worn accessories that do not meet these requirements may

not comply with RF exposure requirements and should be avoided. Use only the supplied or an

approved antenna.

FCC STATEMENT : This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) This device must accept any interference received, including interference that may cause undesired operation. Warning: Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
