• There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software.

Jumped Start, now Air Suspension is Dead

Hello All,

First post here with an unusual problem. I left the key on my 2012 RT-S SE-5 for 4+ hours before I turned off. The battery did not die. The next day, I turned the key on and booted all normal. Hit the starter button, the engine turned over once, weakly, not enough to start, then the computer browned out and rebooted. I attempted to start again with the same result. Engine turns over once, weakly, not enough to start, the system browns out and reboots back to the normal LCD start screen.
Ok, fine, so the battery is weak and Can Am clearly imposes a relay or solenoid that opens automatically if the battery falls below some voltage threshold.
Pull out the charger, put the charger on Start mode, bam... Can Am fires right up. Go out for a ride as normal and the air suspension is dead. Sitting at the bottom with zero psi. The LCD screen initially shows the normal adjustment range and you can move the setting up and down. But the compressor never runs and the normal "sounds" you hear when the air suspension does work are absent. After a couple of minutes, the LCD changes to the dreaded Orange MANUAL screen.

Reviewing many other posts the topic of malfunctioning air suspension does not show anything that relates to my condition. The ACS bolt is installed. I tried all the other ideas including taking the key out and moving away from the machine a long distance for 40+ minutes. Nothing works. The fuses are good. I cannot find the relay to check that it was not damaged by the jump, but this is highly unlikely. If someone can show me where the relay is, I can check it.

Anyone have any clue why a jump start would wipe out the Air Suspension? Worked normally before jump, does not work after the jump. Clearly a strong indicator. I did read some posts about the calibration of the ACS becoming corrupt. I suppose the brown-out power condition of a weak battery could cause this, but I would hope Can Am was smart enough to design the system to survive a weak battery, which will happen "routinely" to all the Can Ams out there, without degrading the machine!

Oh, one last note, NO, i did not reverse polarity the jump start...

Thanks,
Mark

Is it possible that the system restricts non essential functions until the battery has been restored to a certain level? It may also be part of a battery saving feature like many cars have if you leave lights on, etc.
i do not know if that is the case but it is a thought. I suggest charge the battery completely and see if the problem goes away.
 
Might not help you at all, but possibly worth a try - put some air in the rear suspension manually, from an external compressor or pump....


Shortly after I got my RT, I played with the rear air suspension a little & emptied all the air out of it, only to find that the compressor & the automatic levelling wouldn't work afterwards. :opps: At least it didn't work until I manually put about 30 psi into it, then everything worked fine again! :clap:


That was almost 12 months & about 8,000 miles ago, haven't had any problems since. So it might be worth you seeing if adding air manually helps in your case. :thumbup:
