"Service Active Dampening System" - how to diagnosis?

8099 Views 9 Replies 6 Participants Last post by  Kelly_AM
The Service Active Dampening System message popped up on my dash (2015 Hellcat Challenger). I'm done the reading and tried these suggestions
  • Looked for broken or rubbed through wiring. (Didn’t find any and the tires are stock size)
  • Looked for leaking shocks. Didn’t see any.
  • Check fuse 48, it's good (bugger is hiding in the trunk)
  • disconnected the battery for an hour and reconnected.
  • Checked for DTC using the dash menu – nothing listed. Same for a basic scan tool.
Can anyone point me in a direction? Are there any cheap scan tools to will read the Active Damping system codes?

Thanks. I'll try reconnecting the wiring harnesses..

Yes, stock tires and rims. I had read that wider tires would often rub the wiring.
So I scanned the car and I have a code U0139. "Lost communication with active damping control module."

It looks like this. Any idea where it is?
