1 Introduction

Thank you for purchasing the ELM-USB diagnostic interface and OBDTester software. ELM-USB interface and OBDTester software are powerful and professional tools for automotive diagnosis. Please read carefully this User Manual before using the product.

We hope you'll find our products useful. In case you have any questions, problems or feedback please contact as at support@secons.com.

1.1 OBD-II diagnostics

On-board diagnostics - OBD-II are standards related to vehicles diagnostics and reporting capability related to emission system (engine, gearbox, etc.). It's available on vehicles manufactured since 1996 in USA and since 2000 in Europe. These standards are mandatory in European Union since 2001 for petrol engines and since 2003 for diesel engines. These standards are often referred to as EOBD.

OBD-II standard makes possible to read diagnostic trouble codes, control units (ECU) state, sensor values, perform tests, etc.

Standards included in OBD-II and supported by OBDTester software are ISO-9141, SAE J1962, SAE J1850, ISO-14230 (KWP-2000) and ISO-15765 (CAN-BUS).

1.2 OBD-II connector

The OBD-II specification defines standardized hardware interface— female 16-pin (2x8) J1962 connector. The OBD-II connector is required to be within 2 feet of the steering wheel (unless an exemption is applied for by the manufacturer, in which case it is somewhere within reach of the driver).

Shape of connector is shown on the right hand side picture. OBDTester allows to display location of connector in vehicles.

Example list of vehicles supported by OBDTester is at http://www.obdtester.com/carinfo/.

The ELM-USB cable which is part of the product is used to interface between the OBD-II connector in the vehicle and the computer.

1.3 Supported OBD-II protocols

ELM-USB and OBDTester support all of 5 OBD-II protocols - SAE J1850 PWM, SAE J1850 VPW, ISO9141-2, ISO14230-4 (KWP2000), and since 2003 also ISO 15765-4/SAE J2480.

Note: Some products advertise support for 9 or even more protocols. This is because they mistakenly count protocol variants as separate communication protocols. If you add 4 variants of CAN-BUS to our list, you are on 9.

1.4 Supported OBD-II modes

Full OBD2 mode support (Mode 1 to Mode 10/0xA):

• Mode 1: Measured values, readiness code, OBD2 status

• Mode 2: Freeze frame

• Mode 3: Fault codes

• Mode 4: Fault codes clearing

• Mode 5: Oxygen (lambda) sensor tests

• Mode 6: Non-continuously monitored tests

• Mode 7: Fault codes

• Mode 8: On-board devices controlling

• Mode 9: Vehicle information (VIN code, part number, etc).

• Mode 10/0xA: Fault codes

1.5 Functions

• OBD-II state and readiness codes

• Identification

• Vehicle manufacturer specific DTC codes support

• Printing of DTC

• Measured values

• Graphical and textual measured values

• Log if values in format compatible with VCDS VagScope

• Oxygen sensor tests

• Measurement of non-continuous values

• Measurement of engine torque

• Actuators tests

• OBD-II connector (DLC) location image database

• OBDTester is optimized for use on Netbooks such as Asus eee

• Program runs on multiple x86 platforms (Microsoft® Windows®, GNU/Linux, ...)

3 First steps

1. Connect the ELM-USB to your computer. LED indicator should light green.

2. Connect ELM-USB to OBD-II connector in the vehicle. If you cannot find location of the OBD-II connector, you can use OBDTester location image database, available under Lookup OBD-II location from main menu:

3. Set-up OBDTester application

Select Settings from OBDTester main menu and configure ELM-USB port. After click Refresh button OBDTester should find port to which is ELM-USB connected. Choose these port. Click Test Interface to make sure everything is OK, you should see fulfilled Serial number and License status box.

If you've purchased OBDTester PROFESSIONAL license, please click on Activate license button to open activation window and update your license. You have to save settings (or Apply button)by clicking on Save button before activation process.
