OBDII/EOBD VD30 Pro Code Reader

1. General Information

1.1 On-Board Diagnostics(OBD) II

The first generation of On-Board Diagnostics (OBD I) was introduced by

the California Air Resources Board (ARB) in 1988 to monitor basic emission

control components in vehicles. With advancements in technology and

the need for enhanced diagnostics, a more sophisticated system—OBD

II—was developed.

OBD II continuously or periodically monitors emission control systems and

critical engine components through specialized tests. If an issue is detect-

ed, the system activates a Malfunction Indicator Light (MIL) on the dash-

board, typically labeled "Check Engine" or "Service Engine Soon."

Additionally, OBD II records essential diagnostic data to assist technicians

in identifying and resolving problems efficiently.

Key information includes:

• MIL Status: Whether the warning light is activated ("on") or deactivated

("off").

• Diagnostic Trouble Codes (DTCs): Specific error codes stored in the

system.

• Readiness Monitor Status: The completion status of emission-related

self-tests.

1.2 Diagnostic Trouble Codes(DTCs)

Diagnostic Trouble Codes (DTCs) are alphanumeric codes stored by the

vehicle’s OBD II system when a malfunction is detected. These codes help

pinpoint the source of a problem, serving as a guide for troubleshooting.

An OBD II DTC follows a 5-character format:

• First character (letter) – Indicates the affected system:

P = Powertrain (Engine/Transmission)

B = Body (e.g., Airbags, Climate Control)

C = Chassis (e.g., ABS, Stability Control)

U = Network/Communication (e.g., CAN Bus)

• Remaining four digits – Specify the exact issue

OBDII/EOBD VD30 Pro Code Reader

Sub-systems

1 = Fuel and air metering

2 = Ignition system or engine misre

3 = Auxilia emissions controls

4 = Vehicle speed control and idle controls

5 = Computer output circuits

6 = Trabsnussuib cibiks

Systems

B = Body

C = Chassis

P = Powerain

U = Network

Code Type

Geberuc (SAE):

P1, P2

B1, B2

C1, C2

U1, U2

Last two digits identify individual

component within the system

See the following DTC breakdown for a visual explanation of how the

codes are structured.

1.3 Location of the Data Link Connector (DLC)

The Data Link Connector (DLC), also known as the Diagnostic Link

Connector, is a standardized 16-pin port used to connect diagnostic scan

tools to the vehicle's onboard computer.

Typical DLC Locations:

• Most vehicles: Within 12 inches of the dashboard center, typically under

or near the driver’s side.

• Some Asian/European models: Behind the ashtray (may require removal

for access).

• If not visible: Check for a location label or consult the vehicle’s service

manual.

4.1 Read DTC

This function allows you to check stored fault codes in the vehicle's control

modules.

Available Code Types:

• Stored DTCs

• Pending DTCs

OBDII/EOBD VD30 Pro Code Reader

• Permanent DTCs

• Record DTC

4.1.1 Stored DTCs

Stored DTCs are active fault codes that are stored in the vehicle's ECU

when the onboard diagnostic system confirms a problem. These codes

will typically illuminate the check engine light (MIL) immediately upon

detection. Current DTCs can be cleared using the code reader's erase

function, though some may clear automatically after several problem-free

drive cycles if the issue doesn't recur.

4.1.2 Pending DTCs

Pending DTCs are temporary fault codes stored when a potential issue is

first detected by your vehicle's monitoring systems. Unlike regular trouble

codes, these won't turn on the check engine light immediately. The system

keeps them as a warning - if the problem happens again on your next

drive, they'll turn into confirmed trouble codes and activate the warning

light. You can clear these pending codes with your code reader, or they'll

disappear automatically if the issue doesn't recur after several driving

cycles.

These codes are useful for spotting intermittent problems early or check-

ing if a repair fixed an issue.

4.1.3 Permanent DTCs

Permanent DTCs are fault codes that were severe enough to originally

trigger the check engine light (MIL), and remain stored in the vehicle's

computer even after the light turns off. These codes preserve a record of

the fault whether the MIL was cleared manually or stopped illuminating

because the problem didn't reoccur. They automatically erase only after:

(1) the underlying issue is fully repaired, and (2) the system successfully

completes 3 consecutive drive cycles without detecting the fault.

4.1.4 Stored DTC

This function allows you to record the DTCs if there are trouble codes in

the vehicle.

OBDII/EOBD VD30 Pro Code Reader

To read codes from a vehicle:

(1) Select "Read DTC" from the OBDII/EOBD menu using the arrow keys,

then press OK.

(2) Choose the code type (Stored, Pending, or Permanent DTCs) and

confirm with OK.

(3) The tool will display all detected codes along with their descriptions.

4.2 Clear DTC

This function allows you to clear stored diagnostic trouble codes (DTCs)

from the vehicle's ECU with the ignition ON (engine OFF).

To erase codes from a vehicle:

(1) Select "Clear DTC" from the OBDII menu.

(2) Follow the on-screen prompts to confirm and complete the erasure.

(3) Immediately rescan the system to check for remaining codes.

After Erasure:

If codes persist: This may indicate permanent DTCs. Please repair or

replace the affected components before attempting to clear the codes

again.

4.4 Freeze Frame

The Freeze Frame function provides a snapshot of critical vehicle parame-

ters (engine RPM, load, fuel system status, etc.) recorded at the moment a

fault code was triggered. This data helps diagnose intermittent issues by

showing exact operating conditions when the problem occurred.

To access freeze frame Data:

(1) Select Freeze Frame from the OBDII menu

4.6 Vehicle Information

The Vehicle Information function retrieves the vehicle's VIN number,

calibration IDs (identifying control module software versions), and calibra-

tion verification numbers (CVNs), which are values calculated according to

OBDII regulations to verify whether emission-related calibrations have

been modified.

Note that multiple CVNs may be reported for a single control module and

the calculation process may take several minutes to complete. Available

options will vary depending on the connected vehicle.

4.7 O2 Sensor

of the oxygen sensors.

Making a selection displays all of the pertinent O2S parameters for the

specific test.

4.8 On-Board Monitoring (Mode 6)

The On-Board Monitoring(Mode 6) function is useful after servicing or

after clearing a vehicle ECU's memory. It receives test results for emis-

sion-related powertrain components and systems that are not continu-

ously monitored for Non-CAN vehicles. And for CAN vehicles, it receives

test data for emission-related powertrain components and systems that

are and are not continuously monitored. It is vehicle manufacturer who is

responsible for assigning test and component IDs.

NOTE：

Test results do not necessarily indicate a faulty component or system.

To request On-board Monitor Test (Mode 6) results:

(1) Use the UP/DOWN key to highlight On-board Monitor Test(Mode

6) from OBDII/EOBD menu and press the OK key.

4.9 EVAP System Test (Mode 8)

The EVAP System Test (Mode 8) allows the code reader to control opera-

tion of vehicle components, tests of systems.

EVAP(Evaporative Emission Control System) is an automotive system

designed to prevent fuel vapor from escaping into the atmosphere, there-

by reducing air pollution.

Its main functions include:

(1) Preventing Fuel Vapor Leakage: The EVAP system captures and stores

fuel vapor to avoid its escape into the environment while the vehicle is in

operation or parked.

(2) Storing Vapor: The system uses a fuel vapor canister to store vapors,

minimizing their impact on the environment.

(3) Recycling Vapor: When the engine is running, the system directs the

stored vapor back to the combustion chamber via an electromagnetic

valve for re-burning, enhancing fuel efficiency.

(4) Monitoring for Leaks: The EVAP system is equipped with sensors that

monitor pressure changes in real-time to detect any leaks within the

system, ensuring its integrity.

OBDII/EOBD VD30 Pro Code Reader

(5) Improving Fuel Efficiency: By effectively capturing and reusing fuel

vapor, the EVAP system contributes to improved fuel economy and

reduced fuel consumption.

NOTE：

• Some manufactures do not allow tools to control vehicle systems.

• The manufacturer sets the criteria to automatically stop test. Refer to

appropriate vehicle service manual before using this function.

4.10 I/M Readiness

I/M Readiness, or Inspection and Maintenance Readiness, refers to the

status of a vehicle's on-board diagnostic (OBD) system's readiness to

perform emissions testing. It indicates whether the various emissions-re-

lated systems on the vehicle are operating properly and have completed

their self-diagnostic checks. This is crucial for passing state emissions

inspections, as some monitors must be "ready" for the vehicle to be

compliant.

Monitor Status:

• OK - Test completed successfully

• INC (Incomplete) - Test not yet finished (needs more driving)

• N/A (Not Applicable) - This monitor is not required/supported for your

specific vehicle

There are two types of I/M Readiness tests:

• Since DTCs Cleared - shows the status of monitors since the last time

diagnostic trouble codes (DTCs) were cleared.

• This Drive Cycle - shows the status of monitors since the beginning of

the current driving cycle.

The code reader supports these standard OBDII monitor abbreviations

and full names:
