Service Active Dampening System msg, but wiring is fine

NeverEnough · 2022-04-29T15:12:06-0400

Got this message when I cane out of the store today. Got home and looked at the the usual suspect wiring & nothing is broken or rubbed through.

No codes, just the error message. Disconnected the battery for a while & still there. Fiddles with all the wiring, unplugged things and no change.

What else could it be, bad shock(s)? The car rode perfectly fine before this randomly popped up when I started the car after getting out of the store. Now the usual ride from hell with this message on there...

Strange..... I have a rear shock in bad shape and no codes or msg.....
Something similar happen to my truck, after a wash with hi preassure water, but the message dissapear next day.......

Disconnected the battery overnight and that didn't solve the thing. Took it out for a drive today to see if I could find any leaks as far as the shocks are concerned and found none. My guess is it's likely at least one bad shock. Guess I'll have to call the dealer on Monday.

Active Dampening Suspension module is in the left rear trunk wall, behind the trunk liner. Could unplug and replug that in.

Is everything OEM from wheels, shocks, ride height etc?

Wheels are not factory. Rest is. The wheels have been on the car for a while, though

Possibly the TPMS sensors going out. Service Active Suspension issue.

If there was an issue with the TPMS wouldn't they not read properly, though? No problems with seeing tire pressures and not getting any TPMS lights on the dash

That does make sense.

Perhaps the following:

frayed lines (less likely)
active suspension bad fuse
active suspension bad module (15-18 Dodge Challenger Hellcat Active Suspension Damping Module 68305564AB | eBay)

It's not the fuse as I checked that & the lines are not broken

Is it riding fine or does it seem like it is rock hard?
Do you have the Dodge module or an aftermarket suspension module in place?

It's rock hard.
Factory module

Factory module

Mine did that. The rock hard is apparently NO voltage to the shocks at all. Mine did that with an aftermarket module. I know I am not using a trickle charger again. Something about the way a trickle charger works can make the software take a hike. Strange but true. Good luck, look at the module.

How did you determine it was a trickle charger? I've used trickle chargers for years on lots of cars including this one and never had a problem.

How did you resolve your issue then?

The charger was the only thing done to the car in six months. Easy logic. They also agreed that several others identified and had the same problem this past winter. The issue is resolved by resetting or reflashing the software.

I also have used trickle chargers on the car for years. But not any longer. I’ll just use a big charger once a month.

I charge my battery time to time, but always disconect it, do you charge it connected to the car??

Yes. Thanks. I want to keep the power on.

Took the car into dealer today and the cause of the service active dampening system message is...a bad shock. Shock goes out less than 33k miles? Unreal. No, the car does not have a warranty anymore so this is out of pocket for me.
