I drove my rt sm5 with trailer from Tucson AZ to Chattanooga TN. Somewhere along the trip I lost the lights to my trailer. I also lost the reverse as I could not activate the button on the bike. When we brought it to the can am dealership here in Chattanooga this is what they said--Tech found trailer module wires crushed and the module appears to have shorted out. Tech unplugged the trailer module and attached as stock, unit then went into reverse. everything appears to be working without the trailer module connected.-- So now we cannot use the trailer because if we plug it in, it shortens out the reverse and the bike then does not have reverse. The tech stated a $500.00 cost to repair this issue. If we can do this ourselves, we certainly will. THe tech said module cost is $216.50 and labor cost $255.00. Help Spyder Lovers
