Under the seat (on what would be the passenger side of a car) on the 650r there is some kind of connector (picture attached). I haven't taken the time to follow the wires completely yet, but does anyone know what this is? a random powered accesory outlet? if so where do we get the femail end for the plug? is it for a specific acessory? diagnostic port? I honestly have no idea..

Thanks!

this is just a guess, but it looks like a diag port. its not terminated to anything, it actually loks like there is a plug in it

Thats the dummy port. If you were to get a gear indicator, thats where you would plug it. Other than that, I don't know what other uses it has, but I believe it's connected to the ecu. That top part comes off and exposes the actual plug.

OK is your bike a learner bike (Restricted Bike)

That is a diog port but on models sold where learner bikes are to meet a strick standard of power to weight they use 2 things to do this. 1 is a little lug on the throtle plate to restrict how far you can twist your wrist and the 2nd is that plug. that plug does something with the ecu, its meant to make the bike cut out or something if the throttle is moved past the point of the lug.

My bike definitly isn't a leaner.. at least it isn't suposed to be lol

Are you saying that the rest of you on 650r's atleast 2010 650r's (09 should be the same) Don't have this conector?

It's the diagnostic connector. Grounding it flashes up the fault codes using the FI light, or you can get the same functionality with the diagnostic tool.

For the EU, where new full licence holders are restricted to 33 bhp, the throttle movement is restrictde mechanically and a plug in this port tells the ecu to alter the map accordingly. The OP probably has a dummy plug just to keep water out.

There are 2 connectors under the seat.

The loose single wire coloured orange/black is referred to in the Wiring Diagram as the Self Diagnosis Terminal and as the name implies forms part of the trouble shooting procedure for the Fuel Injection (FI) system. Briefly 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 other mounted connector has four wires coloured Light Blue/Black, Black/Yellow, Brown/White and Light Green/White (six wires on ABS models). Kawasaki refers to this plug as the Self Diagnosis System Connector and although no indication of its purpose appears anywhere in either the Ninja 650R (ER-6F) or the ER-6N Service Manual it would appear that this connector is used in conjunction with a dealer tool called the Kawasaki Diagnostic System (KDS).

The KDS 3.0 (until 2007 KDS 2.0) is a software program run from a computer in conjunction with cables and a adapter which are connected to the bike via the Self Diagnosis System Connector. The program can be used by the dealer to do the following:

1. Display ECU and model information.
2. Perform system diagnostics.
3. Display, save, and print service data.
4. Actuate individual injectors and other actuators.
5. Display, save, and print real-time sensor values.
6. Display and print graphs (real-time sensor values).
7. Erase stored service data.

On ABS models KDS 3.0 can be used to diagnose ABS faults and clear stored data in the ABS ECU. The KDS 3.0 unit can be purchased through your dealer or online and the kit comprises:

KDS 3.0 Adapter – (P/N 57001-1648) – Cost approx US$1,040.00
KDS 3.0 Software CD-ROM – (P/N 57001-1650) – Cost approx US$65.00
Comm. Cable 8-pin – (P/N 57001-1649) – Cost approx US$55.00
Comm. Cable 4-pin – (P/N 57001-1688) – Cost approx US$55.00
USB Cable – (P/N C57001-0017) – Cost approx US$20.00
KDS 3.0 User Manual – (P/N 99929-0154-02) - Cost approx US$9.00

In some countries a restriction on engine horsepower (33 hp) is required for new riders. Information is sketchy but the restrictor modification appears to be two parts, an electrical modification utilising the Self Diagnosis System Connector and a screw restricting full rotation of the pulley at the throttle body.

Another use of the Self Diagnosis System Connector appears to be in the fitment of the Gear Indicator accessory.

The plug doesn't act as a limiter. It tells the ecu to modify its mapping to suit the restricted throttle movement. THe main restriction is the screw on the TB.

Any Kawasaki dealer should be able to get one, or just use a bit of wire to link the two pins if someone will post which two it is - I can't remember.
