My 2021 RT LTD threw C210A suspension codes from day 1.
Took it back and the rear leveling linkage was indeed not connected.
They replaced the bolt and checked everything out.
Threw C210A codes on the way home. Took it out to the canyons two up, no codes. One up on the freeway started throwing C210A codes again.
Took it back again. This time they replaced the leveling sensor and checked for leaks. They road tested it for miles, freeway and bumpy roads. Checked the mileage, they had indeed ridden it.
Picked it up yesterday with high hopes. Nope, threw C210A codes again on the way home as soon as I got up to freeway speeds (75).
I think I've figured it out. The bike has to be doing about 70 mph or more and has to have my 240 lb lardy ass on it, or two up. One up it throws codes in 5 or 6 miles, two up in 3 miles.
Thinking about it, the tech must weigh about 150 lbs. So the reason they cannot reproduce it is possibly because they are half my age and hence 2/3 my weight. Well that's my theory.
It goes back next week. Now if it isn't the linkage, the sensor, not an air leak, that leaves the compressor, or calibration. I suppose it could be electronic gremlins but as it throws a code for me in 5 miles and not for them in 30 miles suggests something analogue and not digital.
Even after it has thrown the codes, it rides fine, I suspect it is just not centering correctly for self leveling.
They will be delighted when I call them tomorrow, the poor old tech is going to cry for sure. He's a good guy and seems to know his stuff, it's just one those hard problems where it happens for me but not for them. You can see the optimism in his face every time he hands it back to me. Every time I take it back it's like I'm kicking a puppy. Sigh.
