VDL-1000 - OBD-II

OBD-II
The Heart of a Modern Vehicles Diagnostic System

What is OBD-II?
OBD-II stands for On-Board Diagnostics, II generation. It is a standard which is set by SAE and ISO, which acts as an emission and vehicle diagnostic system. Vehicles newer than 1996 models in the United States, European gasoline models newer than 2001 and European Diesel models newer than 2004 are OBD-II compliant. If you are still not sure if a vehicle is OBD-II compliant simply look under the hood at the Manufacturers label. If it is an OBD-II vehicle, it should be listed there.

Like its predecessor OBD-I, OBD-II was developed with the main purpose of being able to control vehicle emissions. However, unlike its predecessor, OBD-II is implemented worldwide by different vehicle manufactures and in the last years, virtually every passenger vehicle is equipped with it. This sophisticated program in the vehicles main computer system is designed to detect failures in a range of systems and to interact with multiple ECU's throughout the vehicle. For all OBD systems, if a problem is found which is outside the range of normal operation, the computer turns on a Malfunction Indicator Light (MIL) or the "CHECK ENGINE light" to warn the driver, and sets a Diagnostic Trouble Code (DTC) to identify where the problem occurred. This DTC message is stored in the memory of the ECU until it can be downloaded by a technician with the proper scan tool.

Where is it?
If your vehicle is equipped with OBD-II, the Data Link Connector (DLC) is usually found somewhere in the interior compartment, typically in the area below the steering column. By plugging in the supplied cable, the Si-Gate VDL-1000 will be able to record in real time the status of each PID (message) & Diagnostic Trouble Code (DTC) on its Compact Flash card. The VDL-1000 is designed to be able to "ping" the OBD-II CAN network at user specified intervals and read the OBD-II formated data for each PID. (J1850 & ISO9141 bus systems are not supported currently by VDL-1000 SW)
