Turn Signal Auto Cancel

Post by jayhawker » Fri May 17, 2019 9:10 pm



My friends 1500 has a problem with the turn signal not auto canceling after it has sat all winter. It worked fine when it was put away in the late fall. Any Ideas on what may be the solution?

One of the things the auto-cancel depends on is the speed pulses from the speedometer. Is the speedometer working? If so, does the cruise control work? If so, that rules out the speed pulse generator, unless there's a bad connection between the pulses to the cancel unit.

Check on those and report back.

That will be on my list to check on tomorrow. The speedometer works but haven't checked the cruise control

The Cruise control comes on but will not set so looks like the problem lies in the pulse generator, what is the next step?

This is not conclusive the speedo pulses aren't working. I'd first confirm all your cruise cancel switches are working, the front brake lever and clutch lever switches are frequently suspect. Try pushing outward on both the brake and clutch to see if you can get the cruise to set. Or you can check the switches with an ohmmeter.

If still no cruise, we'll dig into the speedo pulses.

Thanks for you input as this is all new for me, I will check the brake and clutch switches to make sure they are open when they are not engaged. Will report back when I have more information.

The switches all appear to be functioning correctly. It seems we must go deeper into this mystery, what is the next step?

Here's the measurements you need to take, especially the speed pulse, as it will cause both the turn signal cancel and the cruise control to not work.


You can also measure the speed sensor pulse at the cruise control connector, that's under the seat - you won't have to take plastic off to get to it that way....

I finally had the time between storms to do the test for the Self-Cancelling Turn Signal System
Here are the results:
Battery voltage white/GRN switch on 12V
Turn Signal On___Pink (Turn Signal Switch R or L) had continuity (Pushed) no continuity
Turn Signal off ___Lt Grn/White (Turn Signal Switch R or L) no continuity (Pushed) had continuity
Speed pulse from speed sensor____white/BLK Switch On _had steady 10V all the time no pulse while rotating wheel
Cancel output BLU/BLK Switch on connector connected 0 volts when flashing 12V when off

Can you set the cruise control when in gear 4 or 5?
Because the same speed pulse signal goes there too.

OP stated in earlier tests cruise isn't working either, we are pretty sure the speed sensor is kaput at this point.

"Speed pulse from speed sensor____white/BLK Switch On _had steady 10V all the time no pulse while rotating wheel"

There's another device that uses the speed pulse, the factory AM/FM/Cassette stereo is supposed to auto-adjust the volume with increased speed, does that work?

Only other possibility is a bad connection somewhere in the speed sensor wiring....

Now to figure out exactly where the speed sensor is, and how to fix it.

Here's what I could find on the speed sensor, looks like the instrument cluster has to come out....




Looks like the speed sensor is still available..... Item #27 below...

From my understanding from my friend whose bike it is that ants had gotten up into the instrument panel sometime and perhaps they are the cause of the problem with the speed sensor or the speedometer. I suspected they might be the problem but wasn't sure where the speed sensor was, but at any rate looks like I'll have to tear into the panel to find out. It is learn as you go experience for me and I appreciate all the advice.

Here's some more manual pages that are referenced in getting the instrument cluster out - you may need them.... :D

Thanks, Didn't realize it was so involved but have come to understand that there is nothing easy about working on a Goldwing.

What year 1500? There were changes to the system.

It is a 1994 GL 1500A

In 94 the cruise control gets it's pulses from the engine speed.

Now that puts another twist to this mystery. Perhaps the man who owns the bike has made a mistake about the year. He bought it used so who knows perhaps I should run the VIN to know for sure what year I'm dealing with.

I believe the split is between 92 - 93. I know I have a 92 and it has the older system. Supposedly by using the engine speed and gear switch, it makes for a more stable cruise control. It also makes it easy to get the cruise control to set higher speeds, by swapping the gear switch leads so the cruise thinks it's in 4th when it's in 5th.

After looking over the 94 wiring diagram, it seems that the turn cancel unit gets it's speed signal from the speedometer, via the LCD unit. So you probably have two problems, not one. The cruise has a boatload of switches that cancel it, so I would start checking there. There is a good step by step guide for that, and the way the switches are wired you can verify a whole group of them at once.

As to the turn signal issue. Just go through the wiring diagram and trace out the signals. They pass through a handful of connectors, so plenty of places for corrosion to work it's evil magic.

Correct but, it still uses speed pulses too.

I saw that. Do you know what it does with them since it is not using that to measure speed?
Cancel the cruise control if you set it while doing a wheelie? :?

Speed memory for the "resume" button if you shift between 4th and 5th. If it relied strictly on the engine pulses, and you were cruising along at 4000 RPM in 4th, shifted to 5th and hit resume, it'd floorboard the throttle trying to get you up to 4000 RPM and 90 MPH! :lol:

It knows what gear you are in via the gear position switch.

The explanation given in the ETM is below. However, since we know that we can manipulate the upper set limit by swapping the gear 4 and 5 inputs, the only function of the wheel speed input seems to be providing the lower set speed for the cruise control unit.

Thanks for that info. Yes, it's obvious that the bit about max speed doesn't apply, or maybe it only checks that if it gets a fifth gear signal.
Since I have the older type, I will just have to slow the pulse frequency if I ever want to increase the max cruise speed.

So I guess it really would keep you from using the cruise control while doing a wheelie. :twisted:
