ESP, BAS, SRS, ABS and ck engine lights in display
 

2003 Mercedes S500L W220 Base
My rear L/H speed sensor seems to have an open circuit ,causing ESP,BAS, SRS< ABS and ck engine light to appear in display and stopped working and are throwing codes and warning lights in display. Does anyone know where I might find a wiring diagram so I can try and troubleshoot the open circuit? Code is C1102-016. L6/3 (LH rear speed sensor). Also get codes P1861, P20CC-8, P20CA-8, which says no S.Sensor signal from ESP module 47-5. Also mentioned ESP and P0500 N47-5 (ESP control module)
I have changed stop light switch, 2 L/H rear speed sensors, ESP and Pump assy. Unhooked battery overnight. Checked all fuses and relays (good)
Any help or ideas would be appreciated. My SDS scanner is in for repair. I was Unable to program or code in the used pump/ESP module before SDS went down. Maybe coding and reprograming isn't required. There was no change after installing. This assy came out of a 2004 S430, mine is a 2003 S500.

Thanks for your time
