On the "Tools" menu there is an item for "Test Interface", this allows the basic interface communications to be tested. 

Note: The following only applies to the Denso USB / LOG BOX v3 Interfaces.

To Test Flashing Mode 

1. Ensure the interface is NOT plugged into an ECU.

2. Put a jumper wire from pin 3 to pin 7 on the interface.

The plug pin out above is the 8 pin Molex plug on the Interface.

3. Connect the USB cable from the Interface to the computer.

4. Move the mode switch on the interface to the right hand side position to the Read / Write mode. 

    Note: The v3 interface may not show the Red led until Test interface has started.

5. Open the Woolich Racing Tuned Software, go to "Tools" then to "Test Interface".

6. Click Test Interface.

Use a  multimeter in a DC voltage setting to perform the following tests.

1. Connect the USB cable from the Interface to the computer.

2. Move the mode switch on the interface to the right hand side position to the Read / Write mode.

3. Open the Woolich Racing Tuned Software.

4. Select and open a Bin file that uses a Denso Interface.

5. Click Read or Write ECU and measure the voltage between pin 4 and pin 8 on the interface, this should be 4.5-5v when in flashing mode (Red LED on)

6. Click Read or Write ECU and Measure the voltage between pin 1 and pin 8 on the interface, this should be 4.5-5v when in flashing mode (Red LED on).
