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!

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?
