C0853Active Damping Control Rear Right
- Generic OBD-II code · Chassis
- Can trigger limp mode
- How the car detects it
- C0853 is undocumented in public sources; no carmaker's list, bulletin or manual mentions it. The title is about the adjustable damper at the right rear. Such dampers only work as well as the inputs behind them: the control unit takes in body and wheel motion from accelerometers and sets each valve accordingly. BMW reprogrammed the variable damper control of X6 (F16) cars built in late 2014 because tolerance spread in the wheel accelerometers made it shut electronic damping off and leave the car on a conventional setting. For the actuator itself, GM's 2011 Saab models (9-5, 9-4X) use C0590 for this corner, and Stellantis uses C15C8 and C15C9 on the Ram 1500 from 2024. A failed rear right channel makes the car ride on fixed damping and shows a suspension warning.
