Lcd screen, cruise control and air controls not working

Postby Burban02 » Tue Jan 13, 2015 8:18 pm



1999 GL1500-
The lcd screen is backlit but the time and radio doesn't show up...nothing. Also th cruise control does nothing and the air ride controls don't work. Bike runs great. No sputtering or starting issues like I've seen in other posts. Just trying to figure out where to start. I Have looked around and some people suggest the ecm? Seems that was more of an ignition problem though. Any ideas ?

The LCD is not just for display only but plays a role in operating those systems, repair/replace LCD to functionality first.
This is what I do
Local and need repair help with your 1500, Valkyrie or ST please PM

I don't have the schematic handy but...the display board needs power to operate.
Start at the basics.Probe the fuses.

Definitely the first thing to do is check your fuse box for any blown fuses. Did this just start happening recently?

I just recently acquired this bike but previous owner said it had been this way for some time. I will check fuses tonight. Lcd lighta up which makes me think it has power? Just doesn't display anything.

The back lighting for the LCD operates independent of the LCD, so you may have back lighting but no display. Like the others have said check the fuses, fuse #10 is the AUX fuse.

The dash lighting (which includes the LCD backlight) is completely separate from the drivers that run the LCD (which are contained primarily inside the radio).

Hi all.
I have also problem with my CC.
I have checked all inputs (switches) and the only one that do not meet the specs is the speed-pulses.
I have a 1989 GL1500 and the schematic states on page 21-9 that it schuold swing between 0-10V.
I only get 0-5.3V. Does anyone got the schematic for the LCD-unit so i can get in there and fix this?
Tha selfcanceling of the turnsignals work OK and uses the same pulses as i understand. Is the CC less sensitive to the pulses and nedd the full voltage swing?
Help me out on this.
Bste regards from a snowy Sweden.
George

I would ignore all the previous owner may have said other than the above.
You have no air, you have no cruise, because your LCD panel displays nothing, you can ignore the air and cruise not working, and the pulse voltage for now. As said before the backlighting is just a backlight, no different to the other instrument backlighting.
It seems to me you need to go straight to the problem, the LCD panel. There are 2 logical reasons to have no display at all, however unlikely.
The LCD panel is not connected
The LCD panel is dead
For all you know someone could have replaced the LCD panel and not plugged something back in, and did not find out until it was back together, or it did not work before it was fitted.

If it were a headlight not working, you would go straight to the bulb, well............ Unfortunately having a LCD panel to pop in is a bit more difficult.
Hopefully you will find a loose or unplugged connector. If everything is plugged in both inside and outside the instrument panel, you need a panel to plug in, or get your panel tested. The only way I have known this done is plugging it into a Wing.
You could ask if someone has a delaminated or bleeding panel you could try.
I would be tempted to try another radio unit, but for me that would be as hard as getting hold of a LCD panel. If I was going to start on it I would remove the instrument panel anyway, and replace ALL the warning light bulbs, regardless of if they work or not.
I would hope it is a loose panel plug, that costs zilch to plug back in.
If at first you don't succeed, hide the evidence.

Hi George. What exactly is the problem. will it not turn on, will it turn on but will not set??

Have you checked both actuator switches and safety switches
Front brake cruise cancel
Clutch cancel
Throttle cancel
Rear brake cruise cancel
4th gear switch
5th gear switch
Cruise on switch
Cruise set switch
Cruise on warning light bulb
Cruise set warning light bulb

Did you perform the checks using the 22 pin cruise connector under the seat

Hi Big Blue.

Hi George. What exactly is the problem. will it not turn on, will it turn on but will not set??

Will "Turn on" ie. Cruise on lamp is lit. Will not "set".

Have you checked both actuator switches and safety switches
Front brake cruise cancel OK
Clutch cancel OK
Throttle cancel OK
Rear brake cruise cancel OK
4th gear switch OK
5th gear switch OK
Cruise on switch OK
Cruise set switch OK
Cruise on warning light bulb OK
Cruise set warning light bulb OK

Did you perform the checks using the 22 pin cruise connector under the seat
Yes.

So, as i said, only speedpulses are not OK.

Seems you know as much as I do at least George,
Your air pump does not work, do you get a pressure display on the panel.
Have you done the constant 12v test at the speed sensor
did you get 8 flicks t the sensor per wheel full rotation.
is the cable ok
Have you checked the cruise filter.
Have you checked relays 5 and 6
Have you checked the solenoid valves
I have no doubt you are now thinking what I am thinking, pipes and control unit.

I have tested 3 or 4 speed sensors and never had to replace one, although I have a spare I took out of a good unit I took the LCD panel from..
You know as well as I it is supposed to flick between 2v and up to 10v, does that mean anything up to 10v, I do not know, and I cannot remember for the life of me seeing the multimeter needle going across less than half way, I cannot remember seeing the voltage dropped to 0 either,

I do not know if the voltage pulse at the speed sensor is different on post 1993 wings (0-5v) with the camshaft speed pulse going to the cruise unit via the ECU, a plug may have poor connection,

way before I have got to this stage the fault has been found, I replaced 2 badly delaminated LCD panels, that cured both air and cruise fault.

Without evidence to back me up I would say that if your speedo is accurate, and the indicators self cancel, I would say the sensor is ok,

there is the cruise actuator by the alternator
Clutching at straws here now.
