Dealer Mode and ECU Codes

This page contains instructions on how to enter the dealer mode.

You will want to put the bike into dealer mode if the "FI" Fault Indicator LED is lit and "FI" is flashing in the display under the speedo. Dealer mode will let you read off a fault code so you can trace the fault. The list of fault codes is lower down the page.

Dealer mode is also used to check the Throttle Position Position (TPS) too. The TPS setting is very important for an engine to run smoothly and fuel properly.

The dealer mode plug is on the left hand side of the bike at the back. You may have to remove the left hand side rear fairing to get to it the first time. I have mine inside the trunk area for easy access.

The White / Red trace and the Black / White trace are the cables we're interested in. Click for a larger picture.

You can use a bit of wire or simply a paper clip inserted into the plug. Short the White / Red trace to Black / White trace. Click for a larger picture.

The Black / White trace is a ground. It's not a problem using a bare paper clip, it doesn't matter if it accidentally contacts the frame etc.

Here's an image from the Workshop Manual. The wires aren't marked or labelled with anything, but the White / Red trace bridged to Black / White trace will put the ECU into dealer mode. (I added the image of the switch) Click for a larger image.

Here's my dash in normal mode displaying the coolant temperature. Click for a larger picture.

In dealer mode the display shows the TPS bar and "C" code. "C00" = no fault. Click for a larger picture.

The manual has more information on setting the TPS. You can download it from my page here!

Dealer Mode LED display. The Bar should be in the middle postion at ~1200rpm idle speed.

Dealer Mode LED display. The bar should be at the top at 1400rpm or more.
