I'm getting tried of canceling the service suspension light so I want to get this figured out. I have Bilstein shocks and struts on all for corners now, I also installed the resistors on all 4 corners where the magnarides were plugged in. After about a year the light came back. I replaced one resistor and tested/swapped the other three with new ones but I still have the light. I'm thinking it's a level sensor now. Truck is a 2015 Denali. Does anyone know if Shocksims still sells the 8 piece kit or is it just the OBD kit? I have an email into them but hoping to get some more testing in this week. Is there an app I can diagnose the suspension system with to see what the truck is reading? Maybe do a relearn. A GM version of AlphaOBD. I have enough resistors to wire into the level sensors but I have not seen anyone say how to wire the three wires. Anyone know where to get the info from? Level sensors are cheap enough but I just don't know which one it could be. Anyway to test them? Also, I don't particularly care for our dealerships here and getting them to do odd things like a relearn is like pulling teeth.

Not that it matters now but I just had the DIC message appear at 69000 miles. Reported to NHTSA, also filed a complaint about the transmission harsh shifts just because I was there and the are violent enough for me to warrant a legitimate report. Sig line 2015 Sierra Denali 1 Wheel bearing at 40000 miles Sharkfin leak 1 month outside cutoff date 8 speed opened up 3 times, still shifts like crap but cannot duplicate Condensor and discharge line leak Radiator replaced 2nd set of brakes Vacuum pump now needs replaced

2015 Denali I would like to add AA but want to keep factory nav for resale purposes. Also my wife just purchased a Highlander because of Toyotas nav system and their next exit list on the highway. I would like to have the AA/ACP function but with an Nav app like Toyota's. Any ideas?
