Help p2158 u0121
2009 Mercedes c300 4matic sport
After driving in heavy rains the next day my check engine Abs Esp and brake lights all illuminated on the dashboard. Also as I’m driving with lights on my cluster goes insane needles drop displaying 0 gas 0 temp 0 speed 0rpms than it’ll start working again. Also get a srs malfunction that comes and goes. I checked all my fuses they seem fine. Checked my battery it’s 12.5 and when car is started 13.5-14.0 so that means battery and alternator is good. I took off all my tires to see if any visable damage to wires or sensors( didn’t see anything wrong). My brake pads still have life left and I also unplugged and replugged my abs module . I have a generic scanner from my old car I got codes p2158 speed sensor”b” and u0121 LOST CONNECTION WITH ABS MODULE. I tired all suggestions I could find online was wondering if anyone knows how to fix this problem. I ordered a icarsoft mb v2.0 that can hopefully tell me what the problem is in detail. But for the meanwhile it’s driving me crazy and I need some help. Thanks forums in advance
so my brake light is on( parking brake isn’t engaged and my brake pads are good) abs light on traction !light on and check engine light and random srs malfunction
