16 RT-L showing Limp Mode, Parking brake warning, and check engine light! Why?

Sorry this thread seems never ending. . .
Today I cheated and removed the muffler to get at the axle nut easier.
I'm guessing some engineer got a bonus for deciding to use extra tough thread locker on the muffler hanger bolt. I cleaned off most of the BRP crap and just added some blue locktite when putting it back together. It was much easier with the muffler off and when backing off the left adjuster a little, I cheated. Put a 6" 5/8 bolt into the hollow axle and tapped it with a dead-blow hammer. Rolled the wheel over a few times and it moved about 1 1/2 credit card off the flange. Technical measurement here. Dropped the rear wheel to the table and then tightened the axle nut. I'm getting too old for 160 ft lbs of torque. Hope to get at least one more short ride in before the snow flies.
Certainly appreciate the help on this forum.

I would be carful pounding on a bolt inside of the hollow axle, you wouldn't want to egg the shaft! Just a thought!! I just put a box end wrench over the nut a tap the other end.
