I recently had an FI fault with my 2006 DL1000. I started to troubleshoot it and asked a few questions here:http://www.vstrom.info/Smf/index.php/topic,8810.0.html
I got fed up/busy and left it alone for a few days but now I'm back at it and have a few questions for the masses.
Some background first:
2006 DL1000, 63,000 kms (40,000 miles) on the odometer, secondaries out since around 10,000 kms (6,000 miles), K&N air filter installed around 3,000 kms (1,800 miles). I put Dale Walker Holeshot slip-ons and TFI box on it this spring, at about 50,000 kms (30,000 miles). The bike has had one major service at a dealer, valve adjustment, coolant change and spark plugs. It was done 2 years ago, around 27,000 kms (17,000 miles). I live in a northern climate so it gets put away in the winter. I do ride rain or shine so it has seen lots of wet weather.
So, about 1-1/2 weeks ago I am riding home. Its cold and rainy. I pull off the highway after a 2-1/2 hour ride and, as I stop at the bottom of the ramp, the red dashboard warning light comes on and the clock started alternating time/FI/time/FI. I have about 2.5 kms (1.5 miles) to home and the bike runs perfectly for the rest of the trip. I park the bike and, basically, forget about the fault. Last Monday, I'm getting ready to go for a ride. The bike starts fine, idles as normal and no warning light. After it warms up a bit, the warning light and FI error re-appear. I abort my ride and roll it back into the garage to start solving the problem. Jumper wire to put it in dealer mode and all I get is C00, no errors. Suit back up, get ready to go and, once again, as the bike warms the light comes on and the time/FI alternate. This time I have my spare key so I leave it running, pop the seat and jumper for dealer mode again. This time I am rewarded with a C28, meaning I have an STV (Secondary Throttle Valve) Actuator Circuit Malfunction. I take off the plastics and gas tank and find the following:
I looked in the throttle bodies and the secondary shafts were turning with no apparent obstruction.
I have checked continuity between the red STVA lead wire and ground...open circuit, okay per manaul.
I have checked STVA resistance...6 ohms, okay per manual (spec is 4.8 - 7.2 ohms).
Poked around and found the wires from the main harness to the STVA were slightly abraded. Have since taped them up.
After taping up the wires I put the airbox and gas tank back on so I could start it again. Bike starts and idles fine, as usual. Again, after a few minutes, the dash light and clock/FI begin again. I shut it down and walked away in frustration/disgust.
Today, I went out to keep digging. I rechecked the STV operation and found mine do not operate as per the manual when you first turn the key
Manual: half open - full close - full open - 75% open - half open (after 20 second delay).
Mine: half open - full open - 75% open - half open (after 20 second delay).
I appear to be missing the "full close" part of the process. The secondary throttle shafts seem to move in unison and with no jittering/binding that others have mentioned. I'm about to go out and check the contacts at the ECM but I thought I'd throw this out to see if anyone had any ideas.
