How to use Suzuki Motorcycle scanner to reset fault codes

I bought a second-hand Suzuki GSR600 K6 Motorcycles last year. Last Monday when I switched from a neural a wired sound from the engine is coming and then the F1 red light illuminated.

I was intended to go a MOTO Triumph Motorcycle diagnostic tool, but it is a little pricey. So I have got myself a rather cheap one special designed for Suzuki motorcycles. I found myself a little tutorial guide on OBDexpress webpage on how to use the Suzuki motorcycle diagnostic tool.

1. Have the ignition key in OFF position.

2. Connect the Suzuki motorcycle diagnostic OBD tool connector to the diagnostic plug of the motorcycle, and connect the USB plug to my Dell 630 Windows XP laptop.

3. Start the OBD tool application.

4. Select neutral, turn ignition On and switch the engine stop switch to RUN position.

5. Remove the seat and behind the battery area and I should find a white 6 pin connector (likely with a black rubber boot on it)

6. Press the "Connect" button. The engine parameters must be shown on the screen.

7. Start the engine to inspect parameters with the engine running.

Then the screen displayed two error codes, C28 and C29 faults codes. I got some clues on google and figured out that F1 light on Suzuki motors is equivalent to a "Check engine light" on vehicles. C28 refers to when no actuator control signal is supplied from the ECM or communication signal does not reach ECM or operation voltage does not reach STVA motor and C29 related to the secondary throttle position sensor. The sensor should produce following voltage "0.15sensor voltage <4.85V". Without the above value, C29 is indicated.

I select "Clear fault code" and then the tool started to reset the error codes. Soon the voltage is back to normal and the F1 light turn off. Note that when you turn the key off, the memory is erased so if you have an intermittent fault you should not turn the key off until you pull the codes.
