    Add Brake Fluid (DOT 4)

    Turn bike off and remove key for 2- 3 minutes, let computer reset itself and maybe it will restart properly.

    That would be the first thing i would try.

    Maybe some others have some additional advice.

    don't forget to remove the key and walk away for a few minutes so it will reset. Good luck.

    Default Let's see..!!

    U0126 is DPS failure. Dynamic power steering. SAS steering angle sensor mounted in the dps indicates the angle of the bars to the VCM. If you had an alignment done and the sas was not corrected this could be the problem even if you changed it it needs to be centered by buds. This unit (dps) uses the most electrical power needs good connections.
    C006C communication on CAN BUS unreliable again connections and buds..(hope you never power washed this machine)
    C0049 brake fluid level...check level the slightest drop a teaspoon will set this off. The sensor switches for the fluid level, pedal, tail brake lights etc can affect this.
    Dealer should be able to find the problems but if it is not at the dealership and no certified mechanic for spyders is available can be tricky. There are after market type buds but unreliable at best. I'm sure they have removed the key taken it away from the unit, reset the computer with buds or disconnected the battery if not you need to so the computers can reset and clear the codes...good luck and if you can let us know what you find...

    If you tried the key walk and disconnecting the battery as well as trying with buds you still have not solved the problem. That means it is still an active code. They will have to test the parts involved according to the shop manual if no help there time to call brp tech support...

    You will have to check with brp cause without buds and a trained tech I don't know how you can clear those codes. You can order a shop manual online and it will show you how to test components. Wish it were easier.

    How did you import the vehicle, without having a dealer?
    These are a technologically sophisticated vehicle that really needs access to the BUDS system that dealers have.
    Good Luck!

    Default ERRRRRRORS

    I had a situation last year where as all kinds of error codes and "LIMP MODE" warnings started happening at startup and while riding. Rebooting helped a bit was not a solution. Service dept. suspected the multi display to be the fault but when they ordered and installed a replacement the problem still occurred. Final outcome...rear wheel speed sensor was defective.
