Application range of vehicle

This OBD II / EOBD decoder is specially applied to all the vehicles that accorded with OBD II standard, including the vehicles for preparing the next generation of protocols – controlling the area network (have the capacity). All the vehicles selling in USA as required by United States Environmental Protection Agency, and 1996 newer (automobile) light trucks must be accorded with OBD II standard. Including all the domestic, Asian and European vehicles. A small amount of 1994 and 1995 petrol vehicles are accorded with OBD II standard. If need to verify if 1994 or 1995 vehicles are accorded with OBD II standard, please check the vehicle emission control information (VECI) label, most vehicles are stuck this label under the engine jacket or near the radiator. If the vehicle is accorded with OBD II standard, and then its label is marked with “OBD II certification”. In addition, the government laws and regulations require all the vehicles that are accorded with OBD II standard must have “General” 16 pin data link connector (DLC). If your vehicle is accorded with OBD II standard, there must a 16 pin DLC (data link connector) below the instrument panel, and a vehicle emission control information label states the vehicle is accorded with OBD II standard.

OBD II diagnosis

When diagnostic instrument detects multiple vehicle control modules, the system will prompt you to select the module that can retrieve the data. Power assembly control module [PCM] and gearbox control module [TCM] are the commonly options.

• Caution: Do not connect or disconnect any test equipment when ignition switch is opening or engine is running.

1. Turn off ignition switch.
2. Find the vehicle 16 pin data link connector (DLC).
3. Insert OBD II wire to vehicle DLC.
4. Turn on ignition switch. Engine stops or runs.
5. Press Return/Confirm button to enter diagnostic menu. A series of OBD2 protocol information will be displayed on the display screen, until the vehicle protocol is detected.

If decoder can not communicate with the vehicle ECU (engine control unit), “Connection error!” will be displayed on the display screen.

✓ Confirm ignition switch is turned on;
✓Check if OBD II connector of decoder is connected to vehicle DLC;
✓ Confirm the vehicle is accorded with OBD2 standard;
✓ Turn off ignition switch and wait for 10 seconds. Turn on ignition switch again, repeat the steps in 5.

If “Connection error” information still appears, and then it may be the communication between decoder and vehicle has the problem. Please contact the local dealer or the Customer Service Department of the manufacturer for getting the help.
