General Information: On-Board Diagnostics (OBD) II

The first generation of On-Board Diagnostics (called 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 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 of “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 follow 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.

Location of the Data Link Connector (DLC)

The DLC (Data Link Connector or Diagnostic Link Connector) is the standardized 16-cavity connector where diagnostic scan tools interface with the vehicle ‘ s on-board 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 connect If the DLC cannot be found, refer to the vehicle’s service manual for the location.

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 other four characters, all numbers, 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:
Identifying specific malfunctioning section of the systems.

OBDII Monitor Readiness Status

OBDII systems must indicate whether or not the vehicle * s PCMs 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 power train 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 scan tool , 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 specific information on getting your vehicle* s OBD monitor system ready, please consult your vehicle owner* s manual.

OBD II Definitions

Power train 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 on board diagnostic system can not turn the MIL off until the 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 on board diagnostics. Some form of a drive cycle needs to be performed after DTCs have been erased from the PCM’s memory. 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 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 parameter to help in identifying the problem. This set of values is referred to as Freeze Frame Data and may include t engine parameters such as engine RPM, vehicle speed, air flow, engine load, fuel pressure, fuel trim value, engine coolant s, ignition timing advance, or closed loop start.

Vehicle Coverage

The KONNWEI KW310 OBDII/EOBD Scanner is specially designed to work with all OBD II compliant vehicles, including those equipped with the next-generation protocol —-Control Area Network (CAN). It is required by EPA that all 1996 and newer vehicles (cars and light trucks) sold in the United States must be OBD II compliant and this includes all Domestic, Asian and European vehicles. A small number of 1994 and 1995 model year gasoline vehicles are OBD II compliant. To verify if a 1994 or 1995 vehicle is OBD II compliant, check the Vehicle Emissions Control Information (VECI) Label which is located under the hood or by the radiator of most vehicles. If the vehicle is OBD II compliant, the label will designate “OBD II Certified” · Additionally, Government regulations mandate that all OBD II compliant vehicles must have a “common” sixteen- pin Data Link Connector (DLC). For your vehicle to be OBD II compliant it must have a 16-pin DLC (Data Link Connector) under the dash and the Vehicle Emission Control Information Label must state that the vehicle is OBD II compliant.

Product Troubleshooting

Vehicle Linking Error
A communication error occurs if the scan tool fails to communicate with the vehicle’ s ECU (Engine Control Unit). You need to do the following to check up:

Verify that the ignition is ON;
Check if the scan tool’ s OBD II connector is securely connected to the vehicle’ s DLC;

Reading Codes

Reading Codes can be done with the key on engine off (KOEO) or with the key on engine running (KOER)
Stored Codes are also known as “hard codes” or “permanent codes”. These codes cause the control module to illuminate the malfunction indicator lamp (MIL) when emission-related fault occurs.
Pending Codes are also referred to as ”maturing codes” or ”continuous monitor codes”. They indicate problems that the control module has detected during the current or last driving cycle but are not considered serious yet.Pending Codes will not turn on the malfunction indicator lamp (MIL). If the fault does not occur within a certain number of warm-up cycles, the code clears from memory.

Erasing Codes

CAUTION: Erasing the Diagnostic Trouble Codes may allow the scan tool to delete not only the codes from the vehicle’s on-board computer, but also “Freeze Frame” data and manufacturer specific enhanced data. Further, the I/M Readiness Monitor Status for all vehicle monitors is reset to Not Ready or Not Complete status. Do not erase the codes before the system has been checked completely by a technician.

This function is performed with key on engine off{KOEO). Do not start the engine.

Retrieving I/M Readiness Status

I/M Readiness function is used to check the operations of the Emission System on OBD2 compliant vehicles. It is an excellent function to use prior to having a vehicle inspected for compliance to a state emissions program. Some latest vehicle models may support two types of I/M Readiness tests: DTCs Cleared – indicates status of the monitors since the DTCs are erased. This Drive Cycle — indicates status of monitors since the beginning of the current drive cycle. An I/M Readiness Status result of “NO” does not necessarily indicate that the vehicle being tested will fail the state I/M inspection. For some states, one or more such monitors may be allowed to be “Not Ready” to pass the emissions inspection. An I/M Readiness Status result of “NO” does not necessarily indicate that the vehicle being tested will fail the state I/M inspection. For some states, one or more such monitors may be allowed to be “Not Ready” to pass the emissions inspection.

“OK” —-Indicates that a particular monitor being checked has completed its diagnostic testing.
“INC” — Indicates that a particular monitor being checked has not completed its diagnostic testing.
“N/A” —-The monitor is not supported on that vehicle.
Use UP/DOWN scroll button to select I/M Readiness from Diagnostic Menu and press ENTER button. If the vehicle supports both types of tests, then both types will be shown on the screen for selection. Use UP/DOWN scroll button, as necessary, to view the status of the MIL light (“ON” or “OFF”) and the following monitors:

Oxygen Monitor Test

OBD2 regulations set by SAE require that relevant vehicles monitor and test the oxygen (02) sensors to identify problems related to fuel efficiency and vehicle emissions. These tests are not on-demand tests and they are done automatically when engine operating conditions are within specified limits. These test results are saved in the on-board computer’s memory. The 02 Monitor Test function allows retrieval and viewing of 02 sensor monitor test results for the most recently performed tests from the vehicle’s on-board computer.The 02 Monitor Test function is not supported by vehicles which communicate using a controller area network (CAN), For 02 Monitor Test results of CAN-equipped vehicles, see chapter “On-Board Mon.Test1”.

On-Board Monitor Test

The On-Board Monitor Test is useful after servicing of after erasing a vehicle’s control module memory. The On-Board Monitor Test for non-CAN-equipped vehicles retrieves and displays test results for emission-related power train components and systems that are not continuously monitored. The On-Board Monitor Test for CAN-equipped vehicles retrieves and displays test results for emission-related power train components and systems that are and are not continuously monitored. Test and components IDs arc determined by the vehicle manufacturer.

Component Test

The Component Test function allows initialization a leak test for the vehicle’s EVAP system. The scan tool itself does not perform the leak test, but commands the vehicle’s on-board computer to start the test. Different vehicle manufacturers might have different criteria and methods for stopping the test once it has been started. Before starting the Component Test, refer to the vehicle service manual for instructions to stop the test.

Use UP/DOWN scroll button to select Component Test from Viewing Vehicle Information

The Vehicle Info, function enables retrieval of Vehicle Identification No. (VIN), Calibration ID(s), Calibration Verification Nos. (CVNs) and In-use Performance Tracking on 2000 and newer vehicles that support Mode 9.

Modules Present

The Modules Present function allows viewing of the module IDs and communication protocols for OBD2 modules in the vehicle.
