2. General Information 2.1 On-Board Diagnostics (OBD) II / EOBD 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.

the connector. If the DLC cannot be found, refer to the vehicle‟s service manual for the location. 2.4 EOBD Readiness Monitors An important part of a vehicle‟s EOBD system is the Readiness Monitors, which are indicators used to find out if all of the emissions components have been evaluated by the EOBD system.

Figure 4.14 “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 the vehicle. The green, yellow and red LEDs provide a quick way to help you determine if a vehicle is ready for an Emission Test.

If a “Stored” Diagnostic Trouble Code is causing the Yellow LED to light, it is still possible that the vehicle will be allowed to be tested for emissions and certified. If a “Pending” Diagnostic Trouble Code is causing the Yellow LED to light, it is still possible that the vehicle will be allowed to be tested for emissions and certified.

Take the vehicle to a professional to have it serviced. The problem(s) causing the red LED to light must be repaired before the vehicle is ready for an Emissions Test. Audio Tone Interpretation The audio tone is configured according to the I/M Readiness Status. This function is invaluable when performing diagnostics and driving at the same time, or working in bright areas where LED illumination alone is not sufficient.

5. Ready Test This function can be used as a convenient readiness test tool by automotive technicians to determine if the tested vehicle is ready for an emission test. By visual and audible indication, you will learn a vehicle’s monitors readiness. 5.1 General Information Repairs to the emissions-control systems of a 1996 or newer vehicle cause the vehicle‟s computer (ECU) memory to be cleared.
Page 45
The purpose of this function 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 emission system. All data shows on one screen, which provides a simple profile of vehicle at a glance, saving diagnosis time and improving technician productivity.
Page 46
After the erase procedure is performed, status of most monitors will be changed. Leave the code reader connected to the vehicle, and select Ready Test from Main Screen. Keep on driving the car till the code reader notifies you safely with color LEDs and audible tone that the drive cycle has been completed and the vehicle is ready, eliminating drive cycle guesswork and confirming readiness status.
NOTE: This function reads off the real time data of emission-related monitoring systems readiness status. Once the code reader has finished other operations, for example, clearing trouble codes, the I/M Readiness Monitor Status program resets status of all the monitors to “INC” condition. In order to set these monitors to a Ready status, the vehicle must be driven through a complete drive cycle.

“N/A” -- The monitor is not supported on the vehicle. The LED and audio tone indications are interpreted as below: LED Interpretation The green and red LEDs provide an easy way to check if emission-related monitoring systems complete their self-diagnostic testing.
