AudioVox Cruise Tutorial ( CCS-100 ) - ST1100\ST1300

When I bought my 2004 ST1300, the Audiovox CC was not working so I tied up the wires and told myself it was for another time. The bike is at rest for three weeks so I decided to upgrade the headlamps and move the lights off the forks to the mirror area but that is for another post. I had all the plastic off and I looked at the CC and decided it was time.

Having experience in electro-mechanical assembly, I am meticulous in looming and routing wires in a tidy, flowing manner. In redoing the previous owner's attempt I was surprised to see poor soldering and crimp techniques, the mating of large gauge wire to small gauge, and wire taps too close to connectors.

Anyway, I separated the wire bundle and created three sub-harnesses: a harness out of the servo, a harness out of the control panel and one that ties the both together. All +12 volt signal wires have connectors installed and I went through a relay. I used a quick disconnect adapter set instead of the Y-harness to clean up the coil area. I tucked the noise suppressor on the blue wire in between the frame and coil. Next comes the electrical tests. In looking at the pictures does anyone have any opinion in what I did ?

Updated thumbnails of the install. Added schematic with kind permission from Dan Bergmen (www.bergmenengineering.com)

After looming and rerouting the wires, I test rode. Pressed "on,” green light lit up, push "set" and CC did not take.

Per the schematic troubleshooting guide, with ignition on, all switches operate as stated. Purple wire did not ground so I added a relay per the schematic. With the ignition on, continuity is now present when brake is released, verified w/ ohmmeter.

I tried setting the dip-switches two ways and both don’t work:
*1st: 1 on, 2 off, 3 off, 4 on, 5 off, 6 off, 7 on (as shown in the picture)
*2nd: 1 on, 2 off, 3 on, 4 off, 5 off, 6 off, 7 off

When CC is on, red LED on circuit board lights up when "set,” "res,” and "brake" is applied. With engine at idle, LED slowly blinks and speeds up with acceleration.

Is this still electrical or mechanical? The cable appears to be routed correctly with no binding. There is vacuum at the servo port but have no idea what constitutes enough vacuum. No vacuum canister was installed but did notice a large amount of hose used and coiled underneath the air-box.

Since everything appears to operate normal, could it be the motherboard? Diaphragm in the servo? Replace or repair the servo?

I really would like to make the CC work but I'm not going to spend much more time on this. Any thoughts would be helpful.

For those of you who are curious on what is inside the Audiovox. Pretty simple set up.

The diaphragm looked good, no cracks or tears. It appears to be of good material, one that will last through temperature and time. Will test to verify it is air tight

Will energize the solenoids to see if they operate. After everything I have done I am convinced it is something in the servo that is not working. Board seems to be fine with no damaged or burnt components.

After re-verifying point-to-point wiring was OK, +12VDC signals was measured to the board connector, the diaphragm and chamber held vacuum, and the board showed no evidence of damage; energizing the solenoids indicated the vac solenoid was stuck. After several hits with 12VDC, it loosened itself up. A drop of light machine oil in each port, connect it back to the bike, lock the throttle at 3000 RPM, hit on and set, voila!, all valves actuated. This could work. Re-assemble the servo, reset dip switches to the default mode, hook everything up, test ride and... it's alive! The CC works; on, set, accelerate, coast, off when brake is applied, resume; it's all there. Yea!!! Sometimes it takes digging deeper to solve the problem.

Here is what I learned during this process:

• Be careful disassembling the servo, tabs are easily broken off, especially the diaphragm chamber. I used five small metal tabs to take the top off. Go slow.
• When mating the the lower and upper servo halves, place the three small o-rings into the solenoid ports and not to the chamber tubes. It makes for effortless seating and the tabs click together easier. Once again be careful and work slowly, you don't want to break any of those tabs.
• Take your time in routing the wires and don't be afraid to cut the excess off. Routing the harness out of harms way pays off big. Loom your wires to prevent exposed wires.
• 
  When looming and using the cowl stay (frame) as a routing & anchor point, it is best to assemble the inner cowling. I had to re-position the wiring slightly and to the inside so it could slip past and meet with the main outer cowl. The convoluted tubing adds protection but also adds bulk.
• 
  After all the plastic was on, I noticed the vent opening where the mirror meets the fairing and thought of all the dust, grime, water, and insect ingress that could potentially wreak havoc to the electrical connections and servo so I chose to block it off. A plastic folder bought at Staples provided the right thickness and was trimmed and placed between mirror and fairing.

Well that's it. Fabricate a bracket and it's time to ride; I want to test the CC on its staying power on a long trip.

Bracketing done, project finished!

I brought the bike up to 75mph and with the modest slopes and valleys of our North TeXas highway system, the speed has held remarkably steady. When, with future maintenance, it is required to remove the airbox I will look at adding a vacuum canister but for now I am incredibly happy that the unit functions at it should.

Ride safe.

This is an excellent article, thanks Paul!

It's good to know that the unit can be opened up.  Jim Neagle, STOC #8083, used Paul's pictures and description to fix his AudioVox which had stopped engaging.  Just a bit of oil on the sticking vacuum solenoid was all that it took!  Saved Jim from buying a whole new unit.
