1 General Information

1.1 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 the 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 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:

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.

1.2 Location of the Data Link Connector

The DLC (Data Link Connector or Diagnostic Link Connector) is the standardized 16-cavity 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 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.

1.3 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 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:

1.4 OBD II Monitor Readiness Statuses

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. to “Ready” or “Complete”, it will remain in this state. A number of factors, including erasing of diagnostic trouble codes (DTCs) with a scan tool 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 specific information on getting your vehicle s OBD monitor system ready, please consult your vehicle owner’s manual.

I/M Readiness option allows to view a snapshot of the operations for the emission system on OBDII/EOBD vehicles. I/M Readiness is a useful function used to check if all monitors are OK or N/A. The vehicle’s computer performs tests on the emission system during normal driving conditions. 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.
When the monitor’s status is:
● OK – vehicle was driven enough to complete the monitor.
● INC (Incomplete) – vehicle was not driven enough to complete the monitor.
● N/A (Not Applicable) – vehicle does not support that monitor. There are two types of I/M Readiness tests:
●Since DTCs Cleared – shows status of the monitors since the DTCs were last cleared.
● This Drive Cycle – shows status of monitors since the start of the current drive cycle.
Below is a list of abbreviations and names of OBD II monitors supported by the code reader.

2.Colored LED and build-in beeper provide both visual and audible reminders for emission check and DTCs. Below is the interpretation of the LED and build- in beeper.
When the LED is :
● Green – Indicates that engine systems are “OK” and working properly (the number of Monitors equipped with the vehicle which have run and performed their self-diagnostic testing is in the allowed range. MIL is off. ).No stored and pending DTCs exist. The vehicle is ready for an Emissions Test.
● Yellow – The tool finds a possible problem. It indicates the following two conditions:
(1) Pending DTCs exist. Please check the I/M Readiness test result screen and use the Read Codes function to view detailed codes information.
(2) Some of the vehicle’s emission monitors have not worked properly. If the I/M Readiness screen shows no DTC (including pending DTC), but the  Yellow LED is still illuminated, it indicates a “Monitor Has Not Run” status.
●Red- Indicates some problems exist with one or more of the vehicle’s systems, and the vehicle is not ready for an Emissions Test. As well there are DTCs found. The MIL lamp on the vehicle’s instrument panel will light steady. The problem that is causing the illumination of Red LED should be fixed before an Emissions Test or driving the vehicle further. The built-in beeper works with the colored LED simultaneous, as an assistant to reflect the I/M Readiness test results:
●Green – two long beeps.
●Yellow – short, long, short beeps.
●Red – four short beeps.
NOTE
The built-in beeper which makes different tones corresponding to different LED indicators is invaluable when the test is performed while driving or in bright areas where LED illumination may not be visible.
