Service Suspension System C0660 2013 Chevy Suburban

If you have the code C0660 and all of your electrical components are good, it’s time to replace your ESC pump. The code is for the exhaust valve being shorted to ground. Please subscribe if this helps you at all. Thanks!

Very good! Do you have a video on the diagnostic tester you use? One preferable that can do Idle Air relearns. I have been in the market for the best aftermarket one for GMs used by a home mechanic. I found something that a mechanic LOVES but forgot the name. Don’t worry about sounding like a commercial. Most people watching are looking to you to do their own work.

I had a c0660 and c 0712 I replaced the the compressor again still nothing . I pull my alc relay I gave it power it clicks I also gave my relay pins power to run pump , pump runs. Am I looking at replacing the Alc control module at this point since my c0660 keeps coming back. Thanks any help is appreciated

What about the level sensors? Since the pump runs when commanded, there’s something that the computer is missing in order for it to be commanded on by the computer.

Keep us posted hope it works out for you!

@Bluecollarmechanics I'm thinking it's the alc computer module above the spare tire. I would think I'd get a code for level sensors. I'll tackle eventually and give an update

Any update for this. I’m having the same issue. Compressor runs when power put to it at the relay.

​@codylawless2643 I'm thinking it's the module under spare tire. I haven't messed with it. The warning comes snd goes
