The electronic connectors are for the self diagnosis terminal for the Fuel Injection (FI) system. It is used to retrieve fault codes stored in the Electronic Control Unit (ECU) memory relating to the FI system. The ECU notifies the rider of troubles in the FI system by lighting the FI light (LED) on the instrument panel whenever a FI or ignition component has a fault. When this connector is grounded in a particular sequence the FI light flashes a fault code indicating the item at fault or in another mode a previous fault that is stored in the ECU memory. The fault codes can also be cleared using this connector.
On my Kawasaki Ninja 650R, I have noticed that there are two electrical connectors under the seat that are not connected to anything?
