OBDII/EOBD Engine System Diagnostics

Vehicle Coverage

The scan tool is specially designed to work with all OBD II compliant vehicles, including 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 American, Asian and European vehicles.
A small number of 1994 and 1995 model year gasoline vehicles are OBD and 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 the 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.

OBDII Diagnostic Menu

This option presents a quick way to check for DTCs, isolate the cause of the illuminated Malfunction Indicator Lamp(MIL), check monitor status prior to emissions certification testing, verify repairs, and perform a number of other services that are emission-related.
Select [Diagnostics] and then press [OK], the system will enter the following screen:

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

4. 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.

5. I/M Readiness
   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 one 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.
   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.

6. O2 Monitor Test
