Every modern Suzuki Bike (since 2003 or even earlier) has a so called Dealer Mode. The Dealer Mode can be enabled by connecting the B/W (Black/White) and W/R (White/Red) Cables at the Suzuki SDS-Plug (white female Connector with black rubber cap) at your Bike near the driver seat.
The Dealer Mode might be helpfull to get the FI Errorcode the ECM detects.
The SDS-Plug at modern Bikes are female 6-Pin (or 4-Pin with older Models) Connector with a black rubber cap.
It's available at easternbeaver.com under Sumitomo MT Sealed Series as Sumitomo „6P090WP-MT Male“ for $4.95 (04.2013).
