General Information

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 systems was developed. This second generation of On-Board 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 specific 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 “Check Engine” or “Service Engine Soon”.
The system will also store important information about the detected malfunction so that a technician can accurately find and fix the problem. Here Below are three pieces of such valuable information:
Whether the Malfunction Indicator Light (MIL) is commanded ‘on’ or ‘off’;
Which, if any, Diagnostic Trouble Codes (DTCs) are stored;
Readiness Monitor status.

Diagnostic Trouble Codes (DTCs)

OBD II Diagnostic Trouble Codes are codes that are stored by the onboard 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; the other three characters, a hex character, 0-9 or A 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:

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 centre of the instrument panel (dash), under or around the driver’s side for most vehicles.
If the Data Link Connector is not located under the dashboard, a label should be there telling the 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.

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) defined by the U.S. Environmental Protection Agency (EPA).
Not all monitors are supported in every vehicle 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:

Misfire
Fuel System
Comprehensive Components (CCM)

Once the vehicle is running, the OBD II system continuously checks the above components, monitoring key engine sensors, watching for engine misfire, and monitoring fuel demands.
Non-Continuous Monitors — Unlike continuous monitors, many emissions and engine system components require the vehicle to be operated under specific conditions before the monitor is ready.

These monitors are termed non-continuous monitors and are listed below:

EGR System
O2 Sensors
Catalyst
Evaporative System
O2 Sensor Heater
Secondary air Injection
Heated Catalyst
A/C system

OBD II Monitor Readiness Status

OBD II systems must indicate whether or not the vehicle’s PCM 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 monitor. Once a monitor is set as “Ready” or “Complete”, it will remain in this state. Several factors, including the 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.”
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 specific information on getting your vehicle’s OBD monitor system ready, please consult your vehicle owner’s manual.

OBD II Definitions

Powertrain Control Module (PCM) — OBD II terminology for the onboard computer that controls the 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 the 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 was onboard diagnostic system cannot turn the MIL off until the necessary repairs are completed or the condition no longer exists.
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-
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. Please refer to the vehicle’s factory service manual for specific 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-specific drive cycles, 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, airflow, 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.

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.
- Currently, there are eleven OBD II Readiness Monitors (or I/M Monitors) defined by the U.S. Environmental Protection Agency (EPA). Not all monitors are supported in every vehicle 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:

Misfire
Fuel System
Comprehensive Components (CCM)

Once the vehicle is running, the OBD II system continuously checks the above components, monitors key engine sensors, watches for engine misfire, and monitors fuel demands.
Non-Continuous Monitors — Unlike continuous monitors, many emissions and engine system components require the vehicle to be operated under specific conditions before the monitor is ready.

These monitors are termed non-continuous monitors and are listed below:

EGR System
O2 Sensors
Catalyst
Evaporative System
O2 Sensor Heater
Secondary air Injection
Heated Catalyst
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.

Data Stream

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

View Freeze Frame

When an emission-related fault occurs, certain vehicle conditions are recorded by the onboard 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 the vehicle.

O2 sensor test

The results of the 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 apply to all vehicles. Therefore, the list generated will vary depending on the vehicle. In addition, not all vehicles support the Oxygen Sensors screen.

On-board monitor test

This function can be utilized to read the results of on-board diagnostic monitoring tests for specific components/systems.

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 the vehicle’s onboard 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.

Vehicle Info

This option displays the vehicle information, such as VIN (Vehicle Identification Number), CID (Calibration ID) and CVN (Calibration Verification Number).

History

Resetting

In addition to its amazing & powerful diagnostic function, Creader Professional 129X also features an Oil lamp reset, an Electronic parking brake reset, Steering angle calibration, a Tire pressure monitor system reset and an Electronic throttle position reset.
There are two methods to reset a service lamp: Manual reset or Auto reset. Auto reset follows the principle of sending a command from the tool to the vehicle’s
ECU to do the resetting. While using manual reset, users just follow the on-screen instructions to select appropriate execution options, enter correct data or values, and perform necessary actions, the system will guide them through the complete performance for various service operations.
