I recently replaced my 13’ Escalades entire suspension back in mid december with OEM parts. It would periodically throw a “service suspension “ DIC message for right front shock open circuit “. It did this before the repairs (same code). After the repairs sometimes a week could go by without an error sometimes it would do throw it for a couple days. Just recently it’s been every time I start the trunk, scanning it always yields “right front shock open circuit “ DTC, it also had a module failure DTC on the list. I’ve tried reconnecting the shock plugs and that didn’t seem too do much, my spidy-sense is leaning towards a possible broken wire or faulty module? Does anyone know if there’s a way to test the shock or plug? I was thinking about swapping struts around? What’s your opinions on how to approach this? Are the suspension modules prone to failure?
Testing magneride strut?

My guess is that you have a wire failure, possibly close to the strut tower itself. If you wiggle the wire, do you get the DIC message?
I haven’t had much time to dig into it but that’s where I plan on looking first. Start peeling back some of the plastic wire loom and check it out. I’ll do a follow up post one I get into it
those front shock connectors are tricky, if you can pull it off by hand then it is not connected properly. it has to be connected with the lock tab open then close the lock tab.
if you have a tech2 you can monitor the shock live data while driving.
I have a bidirectional scanner that displays live suspension information.
I data logged it the other day and everything seemed to be working after clearing the DTC but always come back next ignition cycle. I don’t think I put the blue connector that connects to the strut in the same way you described, I’m thinking I lined it up and pushed it onto the strut. I’ll go run out and just try reconnecting it real quick before I put the kids down for a nap. Thanks for the advice!
I took the blue connector off and sprayed it was electrical cleaner and blew it out with air reconnected everything and same thing. I hooked my scanner up and took some screenshots of the live data
this is the connector I am talking about, it sits on top of the shock rod
the black piece is the locking tab, you pull that off then the spring can be released by pushing it in.
Yeah I took that off cleaned it and put it back on it was completely seated. I briefly check the wires leading to the strut and they’re wrapped in electrical tape. I’ll pull it in the garage this week and check it out a little closer. It’s a little strange that either front damper actuators reading any percentage.
might want to check and clean up the suspension module harness also it is in the back under the spare wheel area and gets exposed to the elements
My scan tool did have a module failure DTC but hasn’t returned after clearing. The “right front actuator open circuit” comes back instantly after clearing though. Id pull it in the shop but I just painted and cleared a set of platinum front and rear bumper covers. I was thinking that I’ll first trace the wires back as far as I can, ill clean the plug end on the module like you suggested, then possibly swapping the struts to see if one of the struts might be faulty. Otherwise I have a used module in my eBay cart
I just read that the by-pass resistance is 3.9 olms. I’m going to try that on my decade box instead swapping struts, that should be a quick test.

You could always, temporarily, add a resistor too the corner that’s triggering. You’d know right away if it was a strut, harness or module.
Yeah I plan on plugging my decade box into the harness after work, see if that changes anything. Funny thing is today it was fine. I did a service call this morning for a good customer of ours at his automotive shop. After getting his heating issue fixed I brought it up to him and he looked it up on his computer and it said the plugs that clip onto the strut often cause this issue and should be replaced. He gave me the part # it’s only 30$ bucks I think I’ll give that a shot.
the same one I pictured?
Yes sir! Perhaps it was coincidental, but when I replaced the struts, I disconnected that connector from the harness. On the left strut, I kept the harness connected and only detached the connector from the strut.
can you post up the part number? I lost the bag mine was in and only have the connector, just in case someone else in the future needs the same thing, I seem to recall it being hard to identify.....
13586171 on eBay it was called “GM OEM CONNECTOR KIT” my local dealership had one on hand but was 10$ more than eBay from a dealership lol
ya that's what I thought, my dealer called it a "gm oem connector"
why no one list's it as a "shock connector" is beyond me, that's the only thing it connects to...........
