Air Suspension Ground strap/ground wire locations

[TommyTwoRams]

Hi everyone, just wondering if anyone has ever looked for or found a schematic that gives the locations for the ground straps on a 4th or 5th gen Ram 1500. I’m having intermittent issues with my AS and after screwing with it I’m starting to think I have a ground problem. I’ve scoured the ‘ol info highway with not much luck. Aside from pulling the passenger seat and center console to get at the air suspension module, I’ve been all over the system with no luck. Any info on this GD air setup would help

I'm in the same boat as you. Had "service air suspension", "service trailer brake" messages and traction control light on the dash all pop up at startup yesterday, can't find a bad fuse anywhere. Suspect it's a ground issue. Did you ever find it?

There's a ground on the frame near the air compressor module and by the filler neck. Those are the only two I can recall. Probably a few more up front if I had to guess

If your cruise is also not working when this happens try this. Remove and clean your rear speed sensors. Try to vacuum loose dust from the port. Rust dust causes the magnet to not sense properly. There is a spot in the tip of the sensor that debris can get into. This solved the multiple codes for me. Shortly after the Suspension compressor had its own issues thought, but their was only a single code. Be careful removing the sensor they can brake. New ones a cheap on Amazon.
