NOTE: SINCE I'VE HAD REPORTS THAT THE THUMBNAILS DON'T WORK AT FULL SIZE, THE FOLLOWING IS WHAT I HAVE FOUND THAT WORKS ON MY COMPUTER.


IF THE PICTURE THUMBNAILS DON'T WANT TO LOAD FULL SIZE THE FIRST TIME YOU TRY, LET THE PAGE SIT OPEN FOR A FEW MINUTES TO ALLOW IT TO COMPLETE LOADING AND TRY AGAIN.

IF YOU START CLICKING THROUGH THE SERIES USING THE ''NEXT'' AND ''PREVIOUS'' TABS, THE FULL SIZE PICTURES START TO APPEAR.
---------------
Dealer mode is the operating state where you can access trouble codes that will be present when the 'FI' light is flashing or when you want to check and adjust the 'Throttle Position Sensor' on the main throttle shaft.

Since there was a question in another thread, about how to do this, it might be a good time to show where and how to go about entering that part of bike operation for the C50

To find the 'Dealer Mode' connector, the right side cover needs to be removed. There is one fastener on the top of the cover - just under the edge of the seat.

It is much easier to remove the bolt and the cover if the seat is off the bike but it is not essential.

When the cover is removed, here is what you will see. [DC01]

NOTE... TO FIND THE PHOTO REFERENCE NUMBER, HOVER YOUR CURSER OVER THE PICTURES.

Reach in over top of the ECM to find a dangling connector with a rubber cover as shown in second picture…. [DC1]
Remove the cover and you will find 4 connections used in the 6 place connector. [DC2][DC3][DC5]

The two that are side by side at one end, are the ones you need to use. The colors shown are good for my bike….. [DC4]

You ‘can’ jumper them in spite of the warning NOT to do it in the service manual.

Just be sure that you don’t short the jumper to the frame OR ANYTHING ELSE….

Some use a paper clip. If you do this, use some tape to cover the middle section of the wire so there is only enough bare to make contact inside the 2 connector terminals and it can't short out if it falls against the frame.

The best thing is to make your own switched jumper with a small on/off switch like I did while I was waiting for the Suzuki one….. only about $20.00. -- [DC6,7,8]

To check your 'Throttle Position Sensor' adjustment you will need to have the engine at operating temperature and the Idle speed set within the specified range.

Once that is done.....

Shut off engine.
Connect the mode switch (key off)
Start engine
Move mode switch to ‘on’.
Wait a couple of seconds for the display to switch from ‘odometer’ to ‘TPS readout’.


You will see a ‘DASH’ infront of a lower case “c” with 2 zeros after it……

-c00 [DC9]


The 'dash' is the indicator for your 'Throttle Position Sensor'

The '00' is where the trouble code will be showing IF the number is anything but
'00'

If the ‘DASH’ is even with the top of the “c” the adjustment is correct.-- [DC9]


Even with the bottom of the “c” or with the top of the zero’s there’s a problem……

The throttle position sensor is found on the bottom shaft of the throttle body on the right hand side.

I've found that you need to remove the tank, or at least lift it and also remove or move the air filter housing out of the way because it is likely that you will find it easier to access the lock screw from under the top frame rail instead of trying to work your way down past the secondary throttle position sensor.




I know that this likely won't answer all the questions but feel free to ask the ones that occur to you.... I just won't guarantee that I will know the answers.....

Awesome write up! Thank you very much.
I noticed in the second picture on the right side of the pic you have 1 or 2 rubber lines just dangling there. They are just to the right of the frame downtube.
Are those vent tubes, or do they need to be hooked to something?

I think that this is the picture to which you refer....

The two that are circled are unused ground wires that are attached to a connector fastened with the frame end of the battery ground on the engine block with the two wires indicated by the arrows. They are for future circuit expansion when needed......

Good eye!!! :biglaugh:

NOTICE!!

After opening this page, the pictures in the opening post take awhile to load so if you find that the pictures don't show full size when you click on them, leave the page open for a few minutes and try again.

Thanks for looking!!
