Hi folks,

Started getting the "Suspension" warning. Bought a (another) scanner that can "see" suspension issues (ICarsoft ) and found out what the code was...C0575!

Watched too many videos and read a bunch of threads, and I started believing I needed the control module. Then I saw one YouTube vid' where the guy did do the module replacement but still had the code; it was his transducer (solenoid). The rears have their transducer integrated internally but the fronts snap on the top of the strut.

So the code drove me to the transducer on top of the front shock/strut. Found a number on top of the connector (PBT-GF30 DELPHI) and that took me nowhere. Finally found on eBay, a gent selling "2004-14 GMC Cadillac Chevrolet Mag Ride Shock Adapter Connector Strut Top" with a part number of 62952473185. I searched that number too - his is the only listing. At $26, I bought two. https://www.ebay.com/itm/256328974812. They're a different color but they have that same useless number on the top and form/fit.

It seems to have fixed the problem. So if the code says, "C0575 Left Front solenoid circuit malfunction" and you're getting voltage at the connector (~ 2.35 VDC), just replace the solenoid.

Hope this helps!

 

Change (1) - found a part number and multiple listings for same: 13586171

 

Open Kimono time: First, I had replaced all four struts/shocks in July; to include the pump. Rears were very worn out.

Started getting the Suspension warning two months later. I've changed the connector on top of the strut, the wire connector that goes to the strut, and the control module (got a used one off eBay and plugged it in - didn't have to reprogram it). I put back in the original air pump and have traced the entire wire loom (no wear spots). I ohmed out the two wires to the connector (under the spare tire in the rear), cleaned the connector (several times), and still got the intermittent warning. I put my original control module back in.

I think control module only scans the suspension on start up. I never saw the warning come on whilst driving.

FINALLY, replaced the front strut (again) and that's seemed to have fixed it...so far.

Hope this helps,

One month later, still working well.

God bless!
