Problem in the rear suspension of GL1500

Have to restart what ? Vehicle ? Did you have the system check for code's ?
The four wheel air suspension system is comprised of the following components:

• Service switch
• Control module
• Two front height sensors
• One rear height sensor
• Compressor and drier assembly (includes vent solenoid)
• Air lines
• Front and rear air spring and shock absorber assemblies
• Four air spring solenoids
• Compressor relay
• Vehicle Dynamic Module (VDM) Diagnostic Trouble Code (DTC) Index NOTE: Repair all other DTCs before C1725 and C1726. Repair DTCs C1990 and C1991 last.

It is possible. If you want to find out look in the area where shock absorbers are mounted. If you see small plastic lines going to the shocks, then you have air suspension. GOOD LUCK FRIEND.

Check to to see if you have an air leak in the air lines from compressor to the shocks with a soapy solution in a spray bottle. If you do not fine a leak the shocks them selves may be leaking. One other thing to check is the air line that goes into the right saddle bag and check the valve core.

Would need to know what DTC'S - diagnostic trouble codes are stored in the module for the autoride suspension . Hooking up a professional type scan tool ,looking at input data to the module etc... Looking at a wiring diagram an testing electrical circuit's using a DMM - digital multi-meter . Reading how the system works ,what all involved in making the system work . This is how a professional Tech would go about diagnosing this .

The automatic level control (ALC) system maintains a desired rear suspension position under all types of towing, hauling and loading conditions. The following components are involved in the operation of the ALC system:
• Air line tubing--Pressurized air from the ALC compressor is pumped to each of the rear shocks via air line tubing.
• Air drier--Pressurized air from the compressor is run through a drier containing a moisture absorbing chemical preventing water accumulation in the rear shocks.
• Compressor--Supplies pressurized air to the rear shocks
• Compressor motor relay--The relay supplies battery positive voltage to the ALC compressor motor.
• Pressure sensor--The electronic suspension control module (ESCM) module provides a 5-volt reference and low reference to the ALC pressure sensor. The module receives the signal voltage that is relative to the air pressure applied to the rear shocks.
• ESCM--Controls the ALC system and electronic suspension control (ESC) system and detects failures in both. The module monitors inputs from the position sensors, and pressure sensor to determine when to raise and lower the vehicle to trim height as the vehicle is loaded or unloaded. The module limits pump activation to 255 seconds to prevent thermal damage.
• Exhaust valve--An electric solenoid activated by the ESCM to vent air pressure from the rear shocks.
• Left and right rear suspension position sensors--The module provides a 5-volt reference and low reference to all 4 of the body-to-wheel suspension position sensors. The sensors send the ESCM a signal voltage that is relative to the rear suspension ride height
• Left and right rear shock absorbers with internal air chambers and dampers--Dampens the rear suspension and maintains trim height depending on the air pressure applied.

1996 Goldwing is a 1200. Air suspension is set with a air hose. If it won't work you have a leak or a bad shock.

You either have a leaking air line , but more likely you have blown a rear shock seal. You can replace the seal yourself. The seals will cost about about $20 per shock and $7 for a bottle of rear shock oil. http://www.bikebandit.com/houseofmotorcycles/1993-honda-gl1500a-gold-wing-aspencade/o/m2359#sch24899

yes go online lots of honda people out there

In my opinion the air ride suspension is one of automobile's biggest mistakes. I see this a lot.

The first thing you must do is isolate the problem.

Jack up the back of the car and remove the rear wheels.

Now your shocks are visible. Inspect the rubber boots in the midsection of the shock, If this is worn or torn they will need to be replaced as they dry out once the integrity of the boot is jeopardized.

Next turn the key forward to turn in the compressor that you hear. And follow the thin black air lines that run into the side of the shock. A lot of times, especially on a vehicle this age, these lines will at some point rub on the frame or other item and have holes. Just listening for air leaks and running your fingers along the lines (feeling for bumps or holes) will give you a quick answer on this.

The only thing left in the system is the compressor itself, just remove the air lines from the shocks and as the compressor runs feel the end for air pressure. If you feel it the compressor is working.

Once you have isolated the issue your vehicle faces, feel free to come back and ask for assistance in replacing them. Be thourough and check everything though because 1 bad element will make future problems inevitable.

there are 2 ways of fixing that problem you can replace whats broken which is more than likely the air bags, which is expensive, or you can get an aftermarket set up with regular springs and do away with the air bag system completely it's not hard to convert it over just unplug the compressor jack up the car to lift the weight off of the suspension put a jack under the rear end housing and loosen the the shocks and lower the rearend housing remove the air bags put springs in their place jack up the rear end bolt shocks back up and your done.
