psm off/abs lights come on after replacing rear struts
 

I just replaced my rear struts and now psm off/abs lights come on. They only come on after I start moving the car. I do think that I might have left some grease on the rotors. Could that be the issue? Or did I break some wiring?

I took both wheels off, sprayed caliper with brake cleaner, looked at the wiring, everything is looking good. psm off/abs lights still come on, any ideas?

Double check the speed sensors, they come from the same harness as the brake wear sensor and is typically disconnected when replacing struts. Maybe it didn't get reconnected or reinstalled properly. Or got damaged. It reads the teeth on the stub axle in front and main axle in back.

Be very careful with brake cleaner
 

It is fine for bare metal parts away from your car. Brake cleaner is a very very aggressive petroleum solvent. I would never spray brake cleaner at a caliper mounted on a car....the solvent can cause havoc with electrical cables and sensors. It is not beyond conception that it could attack the seals in your wheel bearings and shorten the life of CV Boots..
