  • Page 6: General Information

    2. General Information 2.1 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 technology evolved and the desire to improve the On-Board Diagnostic system increased, a new generation of On-Board Diagnostic system was developed.

  • Page 7: Location Of The Data Link Connector (Dlc)

    2.3 Location of the Data Link Connector (DLC) The DLC (Data Link Connector or Diagnostic Link Connector) is the standardised 16-pin connector where diagnostic scan tools interface with the vehicle's on-board computer. If the If the DLC cannot be found, refer to the vehicle‟s service manual for the location.

  • Page 8: Eobd Readiness Monitors

    2.4 OBD II Readiness Monitors An important part of a vehicle‟s EOBD system are the Readiness Monitors, which are indicators used to find out if all of the emissions components have been evaluated by the EOBD system. They are running periodic tests on specific systems and components to ensure that they are performing within allowable limits.

    The TA500 Quad Meter will perform the neccessary checks to ensure that the ECU tests are completed. It also allows a quick check of the vehicle to determine if it is ready to receive an emission test without requiring connection to an analyser or the use of a complicated scan tool.
  • Page 71 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 72 After the erase procedure is performed,the status of most monitors will be changed. Leave the scan tool connected to the vehicle, and select Ready Test from Main Screen. Keep on driving the car until the scan tool notifies you with coloured LEDs and audible tone that the drive cycle has been completed and the vehicle is ready, eliminating drive cycle guesswork and confirming readiness status.

  • Page 73: Led And Tone Interpretation

    NOTE: This function reads off the real time data of emission-related monitoring systems readiness status. Once the scan tool 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.
  • Page 74 “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 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.
