2. How To Use

2.1 Data Link Connector (DLC) Location

The DLC (Data Link Connector or Diagnostic Link Connector) is typically a 16-pin connector where diagnostic code readers interface with the vehicle's onboard computer. The DLC is usually located 12 inches from the center of the instrument panel (dash), under or around the driver's side for most vehicles. If the Data Link Connector is not located under the dashboard, a label should be there indicating its location. For some Asian and European vehicles, the DLC is located behind the ashtray, and the ashtray must be removed to access the connector. If the DLC cannot be found, refer to the vehicle's service manual for the location.

Note: Turn on the ignition of the vehicle. The voltage range of the device should be 9-18V, and the throttle should be in the closed position.

2.2 Application Overview

When the code reader boots up, the Home screen opens, displaying all loaded applications. The following applications are preloaded:

• Diagnostics: Leads to OBDII screens for all 9 generic OBD system tests.
• Lookup: Leads to screens for diagnostic trouble code lookup.
• Help: Provides device OBD function and system instructions.
• Setup: Leads to screens for adjusting default settings to meet user preferences.

Note: Not all function options are applicable to all vehicles. Available options may vary depending on the vehicle's year, model, and make. If an option is not applicable, "X" will be displayed. When connected to the vehicle, the reader automatically checks the status of the I/M monitor and provides a summary report.

1.1.1 Select "Diagnosis"

Click "OK" to enter system diagnosis, then click "OK" again to enter the diagnosis function list.

Diagnosis Function List:

1.1.2 Select "READ CODE"

Click "OK" to select vehicle type and view DTC diagnostic data.

Read Codes Screen:

Select Car Brand:

• FORD
• GM
• CHRYSLER
• BENZ
• BMW
• VW/AUDI

1.2 Select "ERASE CODES"

Clears fault codes.

Erase Codes Screen:

Note: The Erase Codes menu clears all current and stored DTCs from the control module, including temporary ECU information and freeze frame data. Ensure all systems are checked and serviced before clearing codes to avoid losing vital information.

1.3 Select "I/M READINESS"

Click "OK" to view the I/M data flow.

I/M Readiness Status:

I/M Readiness Status (This Drive Cycle):

NOTE:

• To review I/M Readiness status, ensure the ignition key is switched to ON with the engine off.
• Not all monitors are supported by all vehicles.

I/M Readiness is a function to check if all monitors are OK or N/A. The vehicle's computer tests the emission system during normal driving. After sufficient drive time, monitors indicate if the emission system is working correctly. Monitor status:

• OK - Vehicle driven enough to complete the monitor.
• INC (Incomplete) - Vehicle not driven enough to complete the monitor.
• N/A (Not Applicable) - Vehicle does not support that monitor.

There are two types of I/M Readiness tests:

• Since DTCs Cleared - shows monitor status since DTCs were last cleared.
• This Drive Cycle - shows monitor status since the start of the current drive cycle.

1.4 Select "DATA STREAM"

View all data streams. Click "OK" to view the graphics data flow.

Data Stream:

Tips: Use the BACK key to return to the diagnostic menu.

1.5 Select "FREEZE FRAME"

Click "OK" to view the freeze frame data stream.

Freeze Frame Data:

The Freeze Frame menu displays freeze frame data, a snapshot of critical vehicle operating conditions automatically recorded by the on-board computer at the time the DTC was set. It is useful for determining the cause of a fault.

1.6 Select "O2 SENSOR TEST"

Click "OK" to view O2 Sensor data Stream.

O2 Sensor Test:

OBD II regulations require certain vehicles to monitor and test oxygen (O2) sensors to isolate fuel and emissions related faults. The O2 Monitor Test function retrieves completed O2 sensors monitor test results. The O2 Monitor Test is not an on-demand test; O2 sensors are tested when engine operating conditions are within specified limits.

Tips: Different car models may have different numbers of oxygen sensors; check according to the required sensors.

1.7 Select "ON-BOARD MONITORING"

Click "OK" to view On-Board Monitor data streams.

On-Board Monitoring Data:

The On-Board Monitor Test function is useful after servicing or clearing a vehicle ECU's memory. It receives test results for emission-related powertrain components and systems that are not continuously monitored (Non-CAN vehicles) or are continuously monitored (CAN vehicles). The vehicle manufacturer is responsible for assigning test and component IDs.

1.8 Select "EVAP SYSTEM"

Click "OK" to view EVAP data streams.

Evap System Data:

NOTE:

• Some manufacturers do not allow tools to control vehicle systems.
• The manufacturer sets the criteria to automatically stop the test. Refer to the appropriate vehicle service manual before using this function.

2. Select "DTC LOOKUP"

Click "OK" to query fault code analysis.

DTC Lookup Screen:

A screen for DTC Lookup, showing a field to input a DTC (e.g., P0000) and instructions for inputting characters. Instructions indicate using arrow keys to change input and select position, then pressing [OK] to confirm.

3. Diagnostic Trouble Codes (DTCs)

OBDII Diagnostic Trouble Codes 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 serve as a guide to where a fault might be occurring. OBDII Diagnostic Trouble Codes consist of a five-digit alphanumeric code. The first character, a letter, identifies which control system sets the code. The second character, a number (0-3), indicates the code type. The remaining three characters, a hex character (0-9 or A-F), provide additional information on where the DTC originated and the operating conditions that caused it to set.

DTC Example Structure:

Example: P0201

• Systems: P=Powertrain, B=Body, C=Chassis, U=Network. Identifies what section of the system is malfunctioning.
• Code Type: 0 - Generic(SAE), 1 - Manufacturer Specific, 2 - Generic ('P' Codes) and Manufacturer Specific ('B', 'C', and 'U' Codes), 3 - Includes both Generic and Manufacturer Specific Codes.
• Sub-systems: Identifies the system where the problem is located. "P" Code systems are listed below. "B", "C", and "U" Code systems will vary. Examples include: 0 - Fuel and air metering; Auxiliary emission controls, 1 - Fuel and air metering, 2 - Fuel and air metering (injector circuit malfunction only), etc.
