C0852 code meaning
Active Damping Control Rear Left
What C0852 means
Nothing public ties C0852 to a manufacturer; it is absent from every public list and index. The title covers the adjustable rear left damper. Some modern units use two valves per damper, one for compression and one for rebound. Stellantis does so on the 2024-26 Ram 1500 and Dodge Charger and logs the rear left pair as C15C6 and C15C7; its bulletin S2623000031 warns that these faults can only be diagnosed while active, so a module should not be replaced for stored entries, and tap tests on harness and pin fit come first. GM's older single-valve layout on the 2011 Saab 9-4X calls the same corner C0585. Rear dampers sit low and close to road spray, so plugs and cables there suffer most. Electronic damping is switched off until the fault clears.

What to do next
- Note C0852 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
