General Information

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 detected, the system activates a Malfunction Indicator Light (MIL) on the dashboard, 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.

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

See the following DTC breakdown for a visual explanation of how the codes are structured.

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.

Getting Started

Power on your code reader by connecting to vehicle power before using any applications.

Power Connection Method
Vehicle Power Connection

1. Locate the vehicle’s DLC
2. With ignition ON, connect code reader to DLC
3. Device will auto-power on

Application Overview
Upon startup, you’ll see these preloaded applications:

• OBDII/EOBD – Shows OBDII screen for nine OBD system tests
• Live Data – Shows screen of real-time sensor readings and ECU parameter
• I/M Readiness – Shows screen of emissions readings and drive cycle status
• DTC Lookup – Shows screen for diagnostic trouble code lookup
• Battery – Shows screen that tests and displays voltage of vehicle battery
• Settings – Shows screen for access to modify your settings

OBDII EOBD

When selecting OBDII/EOBD from the home screen, the code reader will:

1. Establish communication with your vehicle’s ECU (takes a few seconds).
2. Display the system status,
   • then automatically enter the diagnostic menu with the following test options:

Available Tests

• Read Codes
• Erase Codes
• Oxygen Sensors
• EVAP
• View Freeze Frame
• I/M Readiness
• Vehicle Info
• Data Stream
• Real—Time CIT Ve

Read Codes

This function allows you to check stored fault codes in the vehicle’s control modules.

To read codes from a vehicle:

1. Select I Read Codes” from the diagnostic menu using the arrow keys, then press 0K.
2. The tool will display all detected codes along with their descriptions.

Erase Codes
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 I Erase Codes” from the diagnostic 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.

Oxygen Sensors

• Oxygen Sensors Test opens a screen of tests available for checking the integrity of the oxygen sensors.
• Making a selection displays all of the pertinent O2S parameters for the specific test.

EVAP (Mode 8)

• EVAP (Evaporative Emission Control System) is an automotive system designed to prevent fuel vapor from escaping into the atmosphere, thereby reducing air pollution.

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.

View Freeze Frame

The View Freeze Frame function provides a snapshot of critical vehicle parameters (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 View Freeze Frame Data:

1. Select View Freeze Frame from the diagnostic menu
2. Scroll through recorded parameters using UP/DOWN button
3. View detailed condition readings for each parameter

Note: If no data is available, the display will show “No freeze frame data stored”.

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-related 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 – 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.

NOTE:

• To check I/M Readiness status, ensure the ignition is ON (engine OFF)
• Monitor availability varies by vehicle specifications.

To retrieve I/M Readiness Status data:

1. Select the “I/M Readiness” from the diagnostic menu or select it from the main menu and the following screen displays:
2. Select the desired test, and then it will show as below:

Vehicle Info

• This function retrieves the Vehicle ID Number, Calibration ID (identifying control module software versions), Calibration Verification Numbers (CVNs) and Vehicle Protocol, 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.

Data Stream

• This function allows real-time monitoring of vehicle sensor data and system parameters (PIDs) from the ECU.

CAUTION

• Always park the vehicle before using the code reader
• When recording live data during driving, ensure two occupants are present – one to drive and one to operate the device

NOTE: Vehicle communication speeds and supported PIDs vary by make/model/year. Some parameters may not be available on all vehicles.

Real-Time Curve
This function displays key real-time parameters such as vehicle speed, calculated load value, coolant temperature, and engine RPM in a graphical format.

Live Data (Data Stream)

• This standalone function provides quick access to real-time vehicle data, allowing you to monitor sensor values and system parameters (PIDs) directly from the ECU without navigating through the full OBDII/EOBD menu.
• See 4.8 Data Stream for more detailed information.

I/M Readiness

This standalone function provides the same emissions readiness monitoring as the full OBDII/EOBD menu, letting you check your vehicle’s emissions system status without navigating through multiple screens. See 4.6 I/M Readiness for more detailed information.

DTC Lookup

This function provides instant access to the built-in diagnostic trouble code database, containing both SAE standard and manufacturer-specific code definitions.

To Search for DTC Definitions:

1. Select DTC Lookup from the main menu
2. Enter the code using:
   • UP to navigate character positions
   • DOWN to change digit values
   • OK to confirm
3. View the code definition
   • Note:
     • For manufacturer-specific codes (P1xxx/C1xxx/B1xxx/U1xxx), select the vehicle make
     • If no definition is found, consult the vehicle service manual

Battery

This function provides real-time battery voltage monitoring.
