why would my eps and abs and bas lights be on at same time?

Just my luck I made this $1200+ repair last month @ MB of LB -- parts required were the Shifter, Pin, and Lock. Removel and replacement are made inside the car. It did not look hard for a DIY, I was going to do it myself; however, I was not sure the shifter replacement was the answer. And I would not have not been prepared/aware of the lock and the pin replace. Hope you can diy and save - good luck
