2004 Wing Audio Advance Problem

[FRR]

I know this isn't strictly a trike issue but here goes...I've noticed that my audio advance is not working and hasn't worked since I triked my Wing last Fall. I have it set on high, the symbol is showing up on the screen but it does not get louder as the bike speed increases. My tech said it is not tied to the speedo and certainly not the rear. He said it may be tied to the trannny. Has anyone had this problem or ideas about how this can be dealt with?

I'd be happy to supply additional details if requested. Thanks in advance to anyone and everyone.

This is a copy and paste from my '06 manual. Looks like you'll need a service manual and some spark chasing.... Hope you find an easy fix.

Not to be insulting but did you set the AVC for both the head set and the speakers. They are different function.

AVC (Auto Volume Control) does not work at all
1. Speedometer Inspection
Check that the speedometer functions properly.
Does the speedometer function properly?
NO – Check the speedometer (page 21-23 of Service Manual).
YES – GO TO STEP 2.
2. Speed Pulse Signal Line Inspection
Check the speed pulse signal line (page 18-18).
Is there specified pulse voltage?
NO – Open or short circuit in White/black wire between the combination meter and audio unit.
YES – • Loose or poor related connection.
• Faulty audio unit.

Thank you for your response. Yes, I did check both headset and speakers. I have no idea where I find the Speed Pulse Line.. What kind of voltage does it require?

I've found (at least for me) troubleshooting long distance is just too confusing. As I mentioned before a service manual is needed. Maybe you can find someone close to borrow one from.

I have the manual for every bike I have ever owned... Just can't see not buying one PDQ. In fact I have one for the 2013 GL 1800 I will buy when I sell my '06.

Hope you can get it fixed soon!!

It looks as though the problem is that the back wheel ,(which is how you test it), is now longer there. At least that is how you test it. Looks like I'm sunk. Wonder if anyone else has had their AVC just go out because of age, or because of triking, or any other reason.

After I did this post I happen to think..... Non ABS bikes have ACV but no signal of any sort going to the speed or audio system so I just can not see your lack of rear wheel being the cause.




I don't think the rear wheel has anything to do with it but I might be wrong. I looked in my service manual and the pulses coming from the ABS are not called speed pulses. If your speedometer is working OK then I expect part one of the following is OK. As I recall there are two things to check.....

AVC (Auto Volume Control) does not work at all

1. Speedometer Inspection
Check that the speedometer functions properly.

NO – Check the speedometer (page 21-23 of Service Manual).
YES – GO TO STEP 2.
2. Speed Pulse Signal Line Inspection

Is there specified pulse voltage?
NO – Open or short circuit in White/black wire between the combination meter and audio unit.
YES – • Loose or poor related connection.
• Faulty audio unit.

Step One (page 21-32 of service manual)

Speedometer does not operate
1. Check that the tachometer, coolant temperature
gauge and fuel gauge operate properly.
• If they do not function, check the power
source line and sensor ground line
(page 21-18).
• If they function properly, go to step 2.
2. Check that the engine control module (ECM)
stores failure code 11 (page 6-11).
• If the ECM stores failure code 11, perform the
troubleshooting on page 6-20.
• If the ECM does not store failure codes, go to
step 3.
3. Remove the combination meter (page 21-18).
Place the motorcycle on its center stand, shift the
transmission into neutral and turn the ignition
switch to ON.
Measure the voltage between the White/black
wire terminal (+) of the combination meter 40P
gray connector and ground (–).
There should be 0 V to 5 V pulse voltage while
slowly turning the rear wheel by hand.
• If the pulse voltage appears, replace the
meter/gauge assembly (page 21-21).
• If the pulse voltage does not appear, check
for:
– open circuit in the White/black wire
between the combination meter and vehicle
speed sensor
– loose or poor contact in the related connectors

Step Two (page 18-18 of ETM)

SPEED PULSE SIGNAL LINE
Remove the top shelter (page 3-16 of Service
Manual).
Place the motorcycle on its center stand, then shift
the transmission into neutral.
Turn the ignition switch to ON.
Measure the voltage between the No. 19 White/
black wire terminal (+) of the audio unit connector B
(gray) and ground (–).
There should be 0 V to 5 V pulse voltage while
slowly turning the rear wheel by hand.

Again I hope you get it fixed soon... AVC is not necessary but sure adds to the enjoyment level.

Thanks again. I talked with the tech as CSC and he said he has never heard of this issue. I realize I need to slowly turn the back wheel to properly check some of this, but remember, I have 2 and he suggested doing both. I'm afraid this will end up being way above my knowledge level and I'll probably just have to live with it.

I will miss that AVC for sure. I've even posted another thread to see if anyone has ever had this experience besides me.

Ohhhh so that's what that AVC thingy is for. Learn something new everyday.
