C32 Injector Signal #1 CODE

Hi,
I have searched this forum over the weekend to find a answer for a non starting 03 DL1000. I replaced the battery and now it will crank over but not start. It also shows the code C32 injector signal #1 when I put it in dealer mode.
I'm looking for a way to resolve this without taking it to a dealer.
Could it be a fuse?
A bad connections?

Thanks

Note: The owner is member here but is in france on a trip and I want to have it running for him when he gets back so I became a member of this forum.
I have visited many times because of the quality of info here, and I was going to buy a v strom some years ago.

C32 means
• Injector circuit open or short.
• Injector malfunction.
• ECM malfunction.
#1 means the problem is with the injector on the front cylinder.

Turn the ignition switch OFF.
Check the injector coupler for loose or poor contacts.
If OK, then measure the injector resistance.
Disconnect the TP sensor/injector coupler and measure
the resistance between lead wires.

Injector resistance: 12 - 18 Ohms at 20°C (68°F) Yellow/Red to Gray/White

If OK, then check the continuity between Y/R wire and ground.

It should be infinite Ohms Y/R to Ground

Pat- 2007 DL650A was ridden to all 48 contiguous states. I didn't quite make it to 17,000 miles on the 2012 DL650A.

Thanks for getting back on this.
I can’t get to it for a couple of days; I have Grandpa Duties but will report what I find.
I will have to get a manual for the bike to be sure of what I'm doing.
I had suspected a connection and messed with that but will probably have to remove some plastic.
Again thanks

Where is the best place to get a manual for this bike, 03 DL1000?
I have looked for the factory manual and also found a Haynes but, I'm not too impressed with Haynes in general, but maybe for this bike it is OK.
Any comments or help would be great.
Thanks

The factory manual is best. The FAQ and tech sections at V-Strom Riders International - Index are a big help too.

Well it is looking like it is a Injector Malfunction

• Check the injector coupler for loose or poor contacts.
If OK, then measure the injector resistance……OK• Disconnect the TP sensor/injector coupler and measure
the resistance between lead wires….OK 15.85 Ohms…(58°F)• Injector resistance: 12 - 18 Ohms at 20°C (68°F) Yellow/Red to Gray/White
• If OK, then check the continuity between Y/R wire and ground. Failed• It should be infinite Ohms Y/R to Ground
No continuity registers between Y/R and ground

No continuity is the same as infinite resistance. Your injector passed the tests.

Have to admit that I’m having a problem understanding the next step.
Checking for Gr/W, Gr/B, or Y/R wire open or shorted to ground, poor (5), (6) or (28) connection.


“AH Poo” I’m looking at a electric schematic for a 04 DL650.
Back up and punt…. OK

Plotting out a 03 DL1000 as I type, but still not sure that I know how to be testing for the above.
Is the battery in or out when I do the testing?

I assumed that I’m testing for continuity.

I did find that the PO had installed a Power Commander III.

Also the secondary throttle plates are gone.

Stick to Gr/W and Y/R. Gr/B is for the #2 injector. You are disconnecting the injector from the main harness so the battery is not involved. Based on your reported results, the injector passed the tests but that doesn't prove the injector is okay. It may be stuck mechanically but pass the electrical tests. One thing you can do is swap the injectors and see if the trouble code stays with #1 or moves to #2. If it stays, the problem is in the ECM or the wiring between the ECM and the #1 injector. If it moves to #2, the problem is in the injector.

It occurs to me the problem is more likely to be in the wiring to the front injector. The trouble code is detected electrically and the system may not even be able to detect a sticking injector. It's not impossible though. I'm only thinking about more likely v. less likely.
