1995 s320 the ets, abs lights come on when I put the car into gear, the traction control light flashes and then the two warning lights come on. I can also hear some noise. at this time the power steering seems to be harder. can anyone help.

pull codes. possibly the abs pump or the switch on side of steering gear for speed sensitive steering. pull codes

switch on side of steering gear for speed sensitive steering

Is there a way to test this switch and how do I find it?

Thanks
