I don't think a standard OBD reader is going to show a PSM fault. The default on the PSM is on, the button turn it off and both the switch light and the light on the dash come on. It could be a bad switch. loose wire, etc. etc.

Checking fuses is the easiest thing you could do. I would start there.

Push the other side of the oval button. Maybe you are pushing the wrong side of the button? Just a guess.

Light will glow and PSM OFF orange light on the dash will also be glowing.


With PSM off you should easily be able to break the rear end free and do a donut on an icy or wet surface.

With PSM on, you'll feel it. PSM takes some of the fun out of driving, but is very very good for safety. I leave it on unless I want to snow drift, or autocross, or slide a corner for fun.

I've tried both sides of the switch. And I wasn't aware I could do donuts in a C4s

one of the few awd that can do donuts because of the viscous coupling.

Well I checked the fuses and all were good. I removed the switch and it appears to be working with a multimeter connected but I'm not sure which connections are supposed to get voltage on them. Next time I'm at the dealership I'll have them check it out.

Ok so PSM works. It actually rained for once today and I went out and got on it and the dash light started flashing. Just can't turn it off I guess.

Guess you weren't driving hard after all Still wonder why the switch doesn't lite up...
