How To Use VDIAGTOOL DT-VD10-NEW OBD2 Scanner Code Reader User Manual
The OBD I system is designed to monitor emission control systems and key engine components by performing inner continuous or periodic tests or specific components and Venice conditions, when a problem is detected, the Obull system turns on a warning lamp (MIL) on the vehicle instrument panel to alert the driver typically by the phrase “Check Engine” or “Service Engine Soon”. The system will also store important information about the detected malfunction so that a technician can accurately find and fix the problem. Here below are three pieces of such valuable Information:
- Whether the Malfunction Indicator Light (MIL) is commanded ‘on’ or ‘Off’;
- Which, if any, Diagnostic Trouble Codes (DTCs) are stored;
- Readiness Monitor status.
Diagnostic Trouble Codes (DTCs)
OBD Il Diagnostic Trouble Codes are codes that are stored by the onboard computer diagnostic system in response to a problem found in the vehicle. These codes identify a particular problem area and are intended to provide you with a guide as to where a fault might be occurring within a vehicle. OBD II Diagnostic Trouble Codes consist of a five-digit alphanumeric code. The first character, a letter, identifies which control system sets the code. The other four characters, all numbers, provide additional information on where the DTC originated and the operating conditions that caused it to be set. Below is an example to illustrate the structure of the digits.
Using the Scan Tool
- LCD DISPLAY – Indicates test results. Backlit, 128 x 64-pixel display with contrast adjustment.
- ENTER BUTTON – Confirms a selection (or action) from a menu.
- EXIT BUTTON – Cancels a selection (or action) from a menu or returns to the menu. It is also used to exit the DTC Lookup screen.
- UP SCROLL BUTTON – Moves up through menu and submenu items in menu menu mode. When more than one screen of data is retrieved, move up through the current screen to the previous screens for additional data.
- DOWN SCROLL BUTTON – Moves down through menu and submenu items in menu mode. When more than one screen of data is retrieved, move down through the current screen to the next screen for additional data.
- OBD II CONNECTOR – Connects the scan tool to the vehicle’s Data Link Connector (DLC).
Frequently Asked Questions
Numerous data kinds are accessible through OBD-II in a standard manner, such as real-time metrics like speed, RPM, pedal position, spark advance, airflow rate, coolant temperature, and so on. The “Check Engine” light’s status.
When you connect an OBD-II scanning tool to it, a code usually appears that indicates the nature of the issue. You can also use the scanner to remove the internal code that caused the check engine light to come on in the car. When you do that, the warning light will go out.
Telematics devices can silently handle several types of data, including engine revolutions, vehicle speed, fault codes, fuel consumption, and more, thanks to the OBDII. The telematics device can then utilize this data to calculate fuel usage, excessive idling, speeding, over-revving, start and finish times of trips, etc.
An OBD2 GPS tracker can offer significantly more information than just location and route by connecting to the onboard diagnostics port. It can also communicate other details about the condition of your car, such as real-time DTC codes, to your company.
A standardized hardware interface, the female 16-pin (2×8) J1962 connector, is specified by the OBD-II specification. Type A is used for automobiles running on 12 volts, while type B is used for vehicles running on 24 volts.
The Check Engine light, which turns on when the computer senses an issue, is connected to it. There is only one port, however it may be connected to other programs and scan tools.
On-Board Diagnostic II, or OBD II for short, is the second generation of on-board self-diagnostic equipment mandated for light- and medium-duty vehicles in California.
One of the more popular methods for troubleshooting check engine light codes without an OBD-2 scanner is to use the ignition key. Even though this procedure is simple, figuring out the DTC requires close observation.
To read the engine codes, you will need to turn on most OBD2 scanners because they are battery-operated. On the other hand, some power the device directly from the OBD2 connector.
The connector is the same for all OBD2 pinouts. Except for pins 4 and 16, several pinouts are utilized for various purposes.
