Description:

①LCD DISPLAY — Indicates test results. Backlit, 128 x 64 pixel display with contrast adjustment.

②ENTER BUTTON — Confirms a selection (or action) from a menu. Starts recording live data under manual trigger mode.

③ESC BUTTON — Cancels a selection (or action) from a menu or returns to the menu. It is also used to setup system, exit DTC Lookup screen, or stop data recording when pressed.
④LEFT SCROLL BUTTON — When look up DTC definitions, moves to previous character and views additional information on previous screens if DTC definition covers more
than one screen; deselect all marked PID data when viewing or recording customized live data list; views previous frames of recorded data when playing back live data. It is also used to update DTC library when pressed.

⑤RIGHT SCROLL BUTTON — When look up DTC definitions, moves to next character and view additional information on next screens if DTC definition covers more than
one screen; selects/deselects PID data when viewing or recording customized live data list, and views next frames of data when playing back live data.
⑥UP SCROLL BUTTON — Moves up through menu and submenu items in menu mode. When more than one screen of data is retrieved, moves up through the current screen to the previous screens for additional data.
⑦DOWN SCROLL BUTTON — Moves down through menu and submenu items in menu mode. When more than one screen of data is retrieved, moves down through the current screen to next screens for additional data. It is also used as the language
setup hotkey when pressed.
⑧HELP BUTTON — Provides help information when pressed.
⑨POWER SWITCH — Turns on/off the scan tool when powered by cell battery; resets the scanner when powered by vehicle battery.
⑩OBD II CONNECTOR — Connects the scan tool to the vehicle’s Data Link Connector (DLC).

RUBBER BOOT — Protects the scan tool from drop, abrasion and etc.

Note: obd code reader is also  hot selling at vtoolshop.You can go to have a check. If you have any other questions or anything I can do for you ,please be free to tell us.

When you use your obd code reader , more or less, you’ll face the following problem. Here we focus on how to troubleshooting:

• What else is OBD II testing?

OBD II also tests the catalytic converter and several “systems” that are directly responsible for reducing harmful vehicle emissions.

• What are the test procedures called?

OBD II test strategies are referred to as Monitors.

• When do Monitors run?

Some monitors are designed to run once per Trip and, when they have run to completion, their test results are stored as a pass or fail in the PCM. Non-continuous monitors run once per trip to test vehicle systems that are directly related to emission control: EVAP, EGR, AIR, Oxygen Sensor, and the Catalytic Converter.

• Does anything else happen when a DTC is stored and the MIL is illuminated?

When the first DTC is stored, the PCM takes a “snapshot” of vehicle operating conditions at the instant the code was set.

• How do Trips allow Monitors to Run?

Each monitor needs certain test conditions so it can run to completion and provide accurate test results.
Most Trips include a Key-on, vehicle operating under carefully defined conditions, followed by a Key-off. The Key-off is an important part of some trip definitions. Even though a code has been stored during a trip, the MIL may not illuminate until the next time the ignition is switched on.

• How does the Monitor know if a component passes or fails the test?

The performance of components and systems is compared to test standards. 

If the conditions aren’t right, will the monitor run anyhow?

Until all the enabling criteria are met car diagnostic tool , we won’t have a trip. This ensures that monitors run only when they are supposed to run.

In order to helping our customer have a better knowledge about OBD II,we’d like to provide more knowledge about obd code reader . Here are some rapid fire OBD II questions and answers:

Q: How do we know if a vehicle has an OBD II emissions problem?

A: The MIL will be on and a DTC will be stored in memory. (Multiple DTCs may be stored.)

Q: Can the MIL come on even if the fault in the system doesn’t cause a performance problem?

A: Yes. The MIL is illuminated for emissions problems, not performance problems.

Q: Who turns on the MIL?

A: The PCM

Q How does the PCM know there is a problem?
A: It runs tests called Monitors

Q: When does it run these tests?
A: During normal driving, when conditions are just right to run the test.

Q: How does the PCM know there is a problem?

A: It receives information from sensors and performs tests of its own on actuators to see if they are working

properly.

Q: Can we watch the data used to make these decisions?

A: We can view data parameters on a scan tool.

Q: Are all scan tools created equal?

A: No. But there is a minimum standard for OBD II scan tools. It’s referred to as the Generic scan tool interface.
